Explanation of quotes by person posts

Beginning in March 2017, I started to make quote blog posts that were each focused on an individual person. A list of these posts can be found at this link. The goal of each post was to find my favorite quotes for each person and organize them into a clear structure. In this regard, I attempted to make a rough outline of their important contributions and principles.

I tried my hardest to not misrepresent anybody and I sincerely apologize if I took anybody out of context. If I was unfamiliar with the person's work, I tried to limit the quotes to general philosophy unspecific to that person. It's also important to say that all these posts are a work in progress. As I learn more about a person's work, I try to go back and edit the post with the improved understanding.

The other purpose of these posts is to add to a list of philosophy quotes at this link. I find it useful to have these quotes organized and available especially when I recombine the quotes such as here, here and here.

I should also mention that these posts were largely created using Wikiquote.org. I have the largest gratitude for Wikiquote because without this website, all of these posts would have been much harder to create. Special thanks to the editors who add material to Wikiquote.

The rest of this post is two seemingly contradicting quotes from Friedrich Nietzsche that epitomize what I'm trying to do with the the person posts: to avoid misrepresentation while finding the most valuable insights.
"The worst readers - The worst readers are those who proceed like plundering soldiers: they pick up a few things they can use, soil and confuse the rest, and blaspheme the whole." (Mixed Opinions and Maxims, 1879)
"Philosophers' error - The philosopher supposes that the value of his philosophy lies in the whole, in the structure; but posterity finds its value in the stone which he used for building, and which is used many more times after that for building - better. Thus it finds the value in the fact that the structure can be destroyed and nevertheless retain value as building material." (Mixed Opinions and Maxims, 1879)

This post is a collection of quotes about beliefs. There are 12 quotes divided into 5 sections.

A. Something accepted as true is a belief (3)
B. Every belief is a representation of reality (1)
C. In life, an individual forms a web of beliefs (2)
D. Ideally, every belief should be in congruence with all other beliefs (4)
E. People agree on most aspects of reality (2)

A. Something accepted as true is a belief


David Hume (1711-1776, philosopher):
1. "In our reasonings concerning matter of fact, there are all imaginable degrees of assurance, from the highest certainty to the lowest species of moral evidence. A wise man, therefore proportions his beliefs to the evidence." (An Enquiry Concerning Human Understanding, 1748)

Rene Descartes (1596-1650, philosopher):
2. "The aim of our studies must be the direction of our mind so that it may form solid and true judgments on whatever matters arise." (Rules for the Direction of the Mind, 1628)

Gottlob Frege (1848-1925, philosopher):
3. "A judgement for me is not the mere grasping of a thought, but the admission of its truth." (On Sense and Reference, 1892)

B. Every belief is a representation of reality


Plato (427 BC- , philosopher):
4. "All that is said by us can only be imitation and representation." (Critas)

C. In life, an individual forms a web of beliefs


Ludwig Wittgenstein (1889-1951, philosopher):
5. "What I hold fast to is not one proposition but a nest of propositions." (On Certainty, 1969 posthumous)

Ludwig Wittgenstein (1889-1951, philosopher):
6. "The child learns to believe a host of things, i.e. it learns to act according to those beliefs. Bit by bit there forms a system of what is believed, and in that system, some things stand unshakably fast and some are more or less liable to shift. What stands fast does so, not because it is intrinsically obvious or convincing; it is rather held fast by what lies around it." (On Certainty, 1969 posthumous)

D. Ideally, every belief should be in congruence with all other beliefs


Otto Neurath (1882-1945, philosopher):
7. “Every new statement is to be confronted with existing ones, already brought to a state of harmony between themselves. A statement will be considered correct if it can be joined to them." (Soziologie im Physikalismus, 1931)

Bertrand Russell (1872-1970, philosopher)
8. “Reason is a harmonising, controlling force rather than a creative one." (Our Knowledge of the External World, 1914)

Willard van Orman Quine (1908-2000, philosopher):
9. "Implication is thus the very texture of our web of belief, and logic is the theory that traces it." (The Web of Belief, 1970)

Richard von Mises (1883-1953, mathematician):
10. “No contradiction exists, if the events are correctly interpreted." (Probability, Statistics and Truth, 1957)

E. People agree on most aspects of reality


William James (1842-1910, philosopher):
11. "The most violent revolutions in an individual's belief leave most of his old order standing. Time and space, cause and effect, nature and history, and one's own biography remain untouched." (What Pragmatism Means. Lectures at the Lowell Institute and Columbia University, 1931)

G. E. Moore (1873-1958, philosopher):
12. “I can prove now, for instance that two human hands exist. How? By holding up my two hands and saying, as I make a certain gesture with the right hand, 'here is one hand' and adding, as I make a certain gesture with the left, 'and here is the another'." (Proof of an External World, 1939)

Are humans contributing to global warming?

I believe that humans are contributing to global warming. This post is a collection of reasons and quotes to support my belief. There are 7 quotes divided into 3 sections.

A. Industrial human activities release greenhouse gases into the atmosphere
B. The amount of greenhouse gases in the atmosphere affect the temperature on Earth
C. The temperature on Earth is increasing faster now than any other time in human history

A. Industrial human activities release greenhouse gases into the atmosphere


Intergovernmental Panel on Climate Change:
1. "Anthropogenic greenhouse gas emissions have increased since the pre-industrial era, driven largely by economic and population growth, and are now higher than ever. This has led to atmospheric concentrations of carbon dioxide, methane and nitrous oxide that are unprecedented in at least the last 800,000 years." (Climate Change 2014 Synthesis Report Summary for Policymakers)

David Attenborough:
2. "When I was a boy in the 1930s, the carbon dioxide level was still below 300 parts per million. This year it reached 382, the highest figure for hundreds of thousands of years." (Climate change is the major challenge facing the world, The Independent, 2006)

Rebecca Lindsey:
3. "Based on air bubbles trapped in mile-thick ice cores and other paleoclimate evidence, we know that during the ice age cycles of the past million years or so, atmospheric carbon dioxide never exceeded 300 ppm. Before the Industrial Revolution started in the mid-1700s, atmospheric carbon dioxide was 280 ppm or less." (Climate Change: Atmospheric Carbon Dioxide, 2024)

B. The amount of greenhouse gases in the atmosphere affect the temperature on Earth


Intergovernmental Panel on Climate Change:
4. "Without the natural greenhouse effect, the average temperature at Earth's surface would be below the freezing point of water. Thus, Earth's natural greenhouse effect makes life as we know it possible." (IPCC Fourth Assessment Report: Climate Change 2007, FAQ 1.3 What is the Greenhouse Effect?)

U.S. Energy Information Administration:
5. "When sunlight strikes the Earth's surface, some of it radiates back toward space as infrared radiation (heat). Greenhouse gases absorb this infrared radiation and trap its heat in the atmosphere, creating a greenhouse effect that results in global warming and climate change." (Energy and the environment explained, Greenhouse gases, June 2014)

C. The temperature of Earth is increasing faster now than any other time in human history


Barack Obama:
6. "2014 was the planet's warmest year on record. Now, one year doesn't make a trend, but this does: 14 of the 15 warmest years on record have all fallen in the first 15 years of this century." (State of the Union Address, 2015)

World Meteorological Organization, United Nations:
7. "The global average temperature in 2022 is estimated to be about 1.15 (1.02 to 1.28) °C above the 1850-1900 average." (Eight warmest years on record witness upsurge in climate change impacts, 2022)

Leonardo da Vinci (1452-1519, artist):
10.

(Quoted by The Notebooks of Leonardo da Vinci by Rudolf Flesch)

Michel Foucault (1926-1984, philosopher):

George Henry Lewes (1817-1878, literary critic):
17. "...it is in the selection of the characteristic details that the artistic power is manifested." (The Principles of Success in Literature, 1865)

H. Reality if full of potential concepts

Quotes about economics

This post is some of my quotes about economics. There are 12 quotes listed below.

Econ Factbook


1. "Econfactbook.org is a economic data website that attempts to bring greater transparency to the world economy... The format of Econ Factbook is designed to eliminate excess statistics and only display the structure of an economy. By focusing on the structure, I believe it can help people better understand an economy." (Transparency and the world economy, 2018)

2. "I hope that someday every city and state in the world could have their own page using the same format. Currently economic data about localities is very difficult to find on the internet and I believe centralizing this data in a clear format would be useful." (Transparency and the world economy, 2018)

3. "The format of Econ Factbook is based on the circular flow of income model. The format has a section for each of the five main economic sectors: households, companies, government, banks and the central bank. Each section has a few statistics to illustrate the condition of that sector. In addition to these sections, the format has a section for employment, industries and international accounts." (Transparency and the world economy, 2018)

Current events and academic economics


4. "My undergraduate economics education has been very useful to me and I learned great information. I'm happy to have learned many demand and supply graphs along with other mathematical theories. But as a whole, analysis of current events was not the focus. In order to know what was going on in the real world, I had to read The Economist and other publications outside of class." (Current events and academic economics, 2018)

5. "That's not to say that academic economists completely ignore current events; there are some examples of great current event analysis in economic journals. But as a whole, I believe that current events is of secondary importance within academic economics." (Current events and academic economics, 2018)

6. "Before the financial crisis, there should have been academic economists devoted to analyzing exotic financial products in the actual financial system. These economists would have published papers maybe as early as 2005 to ring the alarm about the widespread fraud subprime mortgage securities. Although this type of work would have been useful, it was largely absent." (Current events and academic economics, 2018)

7. "I believe economists would benefit from reading The Big Short by Michael Lewis. The book explains how hedge fund manager Michael Burry was able to predict the subprime mortgage financial crisis long before anyone else. On the other hand, academic economists were largely blind to the impending crisis." (How to predict a financial crisis, 2017)

Economic statements


8. "I believe the goal of economics is to make accurate representations of economic phenomena. I regard this is the purpose of any branch of knowledge." (Evaluating economic statements, 2017)

9. "When I think about economics, I divide the discipline into five types of statements. Here are the five types: what economic policy should be, historical economic phenomena, current economic phenomena, future economic phenomena, general economic phenomena." (Five types of economic statements, 2018)

10. "Building a DSGE model is cool, but it's only a statement. I believe it's more important to find evidence that supports or disputes an economic statement in order to determine its accuracy." (Evaluating economic statements, 2017)

Confounding variables


11. "There are real mechanical relationships in the social realm that accurately fit mathematical equations. Although I think such relationships exist, I'm more inclined to believe that the vast majority of social reality does not operate mechanistically. There are too many confounding variables in the social realm that can't be inserted into a mathematical equation." (Current events and academic economics, 2018)

12. "Applying the scientific method (i.e. controlled experiments) to social reality is a difficult task. Quasi-experimental methods are worth developing, but we should always be wary about unseen confounding variables. Despite these difficulties, I believe that there are real economic relationships that can be discovered using econometrics." (Current events and academic economics, 2018)

Quotes about knowledge and language

This post is some of my quotes about knowledge and language. There are 12 quotes below. An updated version of this post can be found at this link: Collection of quotes from Knowledge and Representation

Principles


1. "Principles constitute the outline of our knowledge. We can add to this list of principles and create dynamic systems. In this regard, principles help organize our thoughts into coherent structures." (What is a principle? 2018)

2. "I enjoy collecting quotes and organizing them into clear structures. To me, structured quotes usually stick in my mind stronger than continuous prose. Even when I write normally, I try keep my paragraphs short and clear." (Quotes and the organization of thoughts, 2018)

Reason


3. "It's important to know the reasons why you believe something and be able to point to pieces of evidence that support your argument. The benefit of this method is that it forces a person to be explicit about why they believe a certain thing." (What is an argument? 2018)

4. "The first step is to figure out what exactly is being debated. This would be to determine a statement that one side believes is true while the other believes is false. Surprisingly, this can be difficult in some cases but its a necessary pre-requite." (What is bias? 2018)

5. "The second step is for each side to provide a list of concise reasons why they hold their belief. Each side should be limited to about 5 reasons. Each reason should be clearly stated and consist of no more than a few sentences. This enables the structure of the belief to become transparent." (What is bias? 2018)

6. "Instead of arguing against a morphing argument, we can hold each side still and dissect each belief. In this regard, we can discover that some reasons are false or have a weak connection to the proposition." (What is bias? 2018)

Language


7. "I believe that language is formed through establishment rather than usage. For example, imagine that we have a a million different color shades and we want to give a word to each shade. In this situation, we could name every color a separate number. This process would establish many word-concept relationships. Although we wouldn't use every color shade, the meanings would still remain." (What is establishment? 2018)

8. "I believe that almost every word in the English language has multiple meanings... For example, the word 'for' could indicate a length of time or an occasion in a series. Another example, the word 'in' could mean that something is surrounded by something else or refer to a condition." (What is literal? 2018)

9. "Instead of trying to differentiate between objective and subjective statements, I think of statements existing along a continuum. I believe there are too many unseen misinterpretation traps to safely conclude that a statement is 100% objective (except for mathematics and logic symbols). As a resolution, I believe we should use the word 'objective' in a subjective manner." (What is objective? 2018)

10. "These examples show that being perfectly literal is somewhat of an elusive task. For most words, it's not clear what the primary meaning is. In this regard, we can only subjectively choose what we believe is most literal meaning." (What is literal? 2018)

Cogito


11. "I exist. Consciousness exists. Experience exists. A sense exists. A perception exists. Reality exists. Time exists... I believe that these seven propositions are necessary for any hallucination to happen. In this regard, even the most elaborate hallucination could not negate any of these propositions." (What is a fact? 2018)

12. "If the self didn't exist, there would be nobody to view the hallucination. If consciousness didn't exist, the hallucination wouldn't have been seen. If experience didn't exist, the hallucination wouldn't have been endured. If a senses didn't exist, there would be no way to access data about the hallucination. If a perception didn't exist, the hallucination wouldn't have been perceived. If reality didn't exist, there would be nothing. If time didn't exist, there would be no seconds to experience the hallucination." (What is a fact? 2018)

Top 32 words to define in philosophy

Photo license: CC BY 2.0

I believe that many of the disagreements in philosophy are caused by a divergence on the meaning of a word. To make things more difficult, if you look up the definition of a word in multiple dictionaries, you often won't find a clear consensus. For this reason, I believe that defining words is an important endeavor in philosophy.

The most famous example of this is the debate over the meaning of 'science', which is known as the 'demarcation problem'. Defining 'science' is particularly important because the word 'science' carries weight and significance. Many people regard science as the best method for establishing knowledge about reality. But if you ask the average person, 'What is the definition of science?' they probably won't provide a clear and satisfactory answer. For this reason, many philosophers have attempted to establish a clear meaning of 'science'.

The rest of this post is a ranking of what I believe are the 32 most important words to define in philosophy and I have provided my definition for each word. A longer list of definitions can be found at this link.

1. Philosophy: study of fundamental nature

7. Phenomenology: study of immediate perception
8. Experience: totality of past and present senses
9. Truth: 1. accurate representation of reality; 2. actual state of affairs
10. Religion: belief in or worship toward a divine supernatural power
11. Understanding: 1. condition of knowing the explanation of something; 2. condition of having competent knowledge in something
12. Consciousness: faculty that enables a being to be aware of experience
13. Reason: 1. process of forming conclusions using explicit reasons or premises; 2. something intended to support the accuracy of a proposition; 3. something that explains something else
14. Language: written or spoken symbols
15. Fact: 1. something known with absolute certainty; 2. something known with absolute certainty with the exception of hallucinations and extreme coincidences

Jean-Francois Lyotard (1924-1998) was a French philosopher best known for his analysis of knowledge distribution and postmodernism. Wikipedia says,
"His interdisciplinary discourse spans such topics as epistemology and communication, the human body, modern art and postmodern art, literature and critical theory, music, film, time and memory, space, the city and landscape, the sublime, and the relation between aesthetics and politics." (Wikipedia: Jean-Francois Lyotard, 7.1.21 UTC 20:05)
The rest of this post is some quotes from Lyotard.

Postmodernism


"I define postmodern as incredulity towards metanarratives." (The Postmodern Condition: A Report on Knowledge, 1977)

Knowledge as a commodity


"Knowledge is and will be produced in order to be sold, it is and will be consumed in order to be valorized in a new production..." (The Postmodern Condition: A Report on Knowledge, 1977)

Art and the sublime


"I shall call modern that art which... presents the fact that the unpresentable exists. To make visible that there is something which can be conceived and which can neither be seen nor made visible." (Goodreads.com)

"The sublime is not mere pleasure as taste is - it is a mixture of pleasure and pain... Confronted with objects that are too big according to their magnitude or too violent according to their power, the mind experiences its own limitations." (Peregrinations Law Form)

John Rawls and justice

John Rawls (1921-2002) was an American political philosopher best known for his analysis of justice and the 'original position' thought experiment. Economist Will Hutton said,
"This means society should build what Rawls calls an 'infrastructure of justice' that ensures everyone has access to key primary goods - some reasonable level of income and material wellbeing, opportunity and basic rights and liberties - which allow them to consider they have been given a proper chance to achieve full membership of society."
Writer Steven M. Smith said,
"Rawls is a philosopher for our time. His desire is to render both theoretically and practically legitimate and redistributivist polices of the prosperous North Atlantic welfare states." (The Philosopher of Our Times, The New York Sun, 2007)
The rest of this post is some quotes from Rawls.

Original position


"A just society is a society that if you knew everything about it, you'd be willing to enter it in a random place." (AZQuotes.com)

Justice


"The concept of justice I take to be defined, then, by the role of its principles in assigning rights and duties and in defining the appropriate division of social advantages." (A Theory of Justice, 1971)

"A conception of justice cannot be deduced from self evident premises or conditions on principles; instead, its justification is a matter of the mutual support of many considerations, of everything fitted together into one coherent view." (A Theory of Justice, 1971)

Equality


"This organizing idea is that of society as a fair system of social cooperation between free and equal persons viewed as fully cooperating members of society over a complete life." (Political Liberalism, 1993)

"In all sectors of society there should be roughly equal prospects of culture and achievement for everyone similarly motivated and endowed. The expectations of those with the same abilities and aspirations should not be affected by their social class." (A Theory of Justice, 1971)

Jacques Lacan and structuralism

Jacques Lacan (1901-1981) was a French psychoanalyst best known for his contributions to structuralism and the philosophy of language. Literary critic Norman Holland said,
"Lacan's most widely quoted maxim is, 'The unconscious is structured like a language' and like that sentence, Lacan's whole oeuvre rest on a certain idea of language. His proclaimed 'return to Freud' meant remedying Freud's failure to use 'modern' linguistics. 'Modern' linguistics for Lacan, however, means a turn-of-the-century linguistics - specifically, Ferdinand de Saussure's." (The Critical I, 1992)
The rest of this post is some quotes from Lacan.

Structuralism


"Meaning is produced not only by the relationship between the signifier and the signified but also, crucially, by the position of the signifiers in relation to other signifiers." (Goodreads.com)

"Nature provides - I must use the word - signifies, and these signifies organize human relation in a creative way, providing them with structures and shaping them." (The Four Fundamental Concepts of Psycho Analysis, 1978)

"For the signifier is a unit in its very uniqueness, being by nature symbol only of an absence." (AZQuotes.com)

Language


"The man who is born into existence deals first with language; this is a given. He is even caught in it before his birth." (Interview, 1957)

"I always speak the truth. Not the whole truth, because there's no way, to say it all. Saying it all is literally impossible: words fail. Yet it's through this very impossibility that the truth holds onto the real." (Goodreads.com)

"The real is what resists symbolization absolutely." (The Seminar of Jacques Lacan: Freud's Papers on Technique)

"As is known, it is in the realm of experience inaugurated by psychoanalysis that we may grasp along what imaginary lines the human organism, int he most intimate recesses of its being, manifests its capture in a symbolic dimension." (AZQuotes.com)

Subconscious


"The knowledge that there is a part of the psychic functions that are out of conscious reach, we did not need to wait for Freud to know this!" (AZQuotes.com)

"Discontinuity, then, is the essential form in which the unconscious first appears to us as a phenomenon - discontinuity, in which something is manifested as a vacillation." (The Four Fundamental Concepts of Psycho Analysis, 1978)

"The unconscious is structured like a language." (AZQuotes.com)

Desire


"...Desire, a function central to all human experience, is the desire for nothing nameable. And at the same time this desire lies at the origin of every variety of animation." (Goodreads.com)

Wolfgang Amadeus Mozart and melody

Wolfgang Amadeus Mozart (1756-1791) was an Austrian composer best known for his contributions to Classical period of music. Composer Carl Ditters von Dittersdorf said,
"Mozart is undoubtedly one of the greatest of original geniuses, and I have never known any other composer to posses such an amazing wealth of ideas. I wish he were not so spendthrift with them. He does not give the listener time to catch his breath, for no sooner is one inclined to reflect upon a beautiful inspiration then another appears ever more splendid, which drives away the first, and this continues on and on, so that in the end one is unable to retain any of these beauties in the memory." (Autobiography, 1799)
The rest of this post is some quotes from Mozart.

Music


"The music is not in the notes, but in the silence between." (Goodreads.com)

"I choose such notes that love one another." (AZQuotes.com)

"Melody is the essence of music." (Quoted in Reminiscences of Michael Kelly... by Henry Colbern)

"...the most necessary, most difficult and principal thing in music, that is time..." (Letter to Leopold Mozart)

"The best way to learn is through the powerful force of rhythm." (AZQuotes.com)

"The organ is in my eyes the king of all instruments." (Mozart's Letters)

Creation


"I am never happier than when I have something to compose, for that, after all, is my sole delight and passion." (AZQuotes.com)

"You know that I immerse myself in music, so to speak - that I think about it all day long - that I like experiments, studying, reflecting." (Goodreads.com)

"I pay no attention whatever to anybody's praise or blame. I simply follow my own feelings." (Goodreads.com)

"Neither a lofty degree of intelligence nor imagination nor both together go to the making of genius. Love, love, love, that is the soul of genius." (Goodreads.com)

"I really do not aim at any originality." (AZQuotes.com)

Religion


"God is ever before my eyes. I realize his omnipotence and I fear his anger; but I also recognize his compassion, and his tenderness towards his creatures." (AZQuotes.com)

Enrico Fermi and nuclear physics

Enrico Fermi (1901-1954) was an Italian physicist best known for creating the first nuclear reactor. Novelist C. P. Snow said,
"If Fermi had been born a few years earlier, one could well imagine him discovering Rutherford's atomic nucleus, and then developing Bohr's theory of the hydrogen atom. If this sounds like hyperbole, anything about Fermi is like to sound like hyperbole."
The rest of this post is some quotes form Fermi.

Nuclear weapons


"Such a weapon goes far beyond any military objective and enters the range of very great natural catastrophes... The fact that no limits exist to the destructiveness of this weapon makes its very existence and the knowledge of its construction a danger to humanity as a whole. It s necessarily an evil thing considered in any light." (Official General Advisory Committee report for the Atomic Energy Commission, 1949)

"Whatever Nature has in store for mankind, unpleasant as it may be, men must accept, for ignorance is never better than knowledge." (Goodreads.com)

"Actually there was no choice. Once basic knowledge is acquired, any attempt at preventing its fruition would be as futile as hoping to stop the earth from revolving around the sun." (Collected Papers of Enrico Fermi, 1939-1954)

"It is clear that the use of such a weapon cannot be justified on any ethical ground which gives a human being a certain individuality and dignity even if he happens to be a resident of an enemy country." (Goodreads.com)

Nuclear science


"Although the problem of transmuting chemical elements into each other is much older than a satisfactory definition of the very concept of chemical element, it is well known that the first and most important step towards its solution was made only nineteen years ago by the late Lord Rutherford, who started the method of the nuclear bombardments." (Nobel lecture, 1938)

Johann Sebastian Bach and God


Photo source: Wikimedia Commons, Elias Gottlob Hausmann

Johann Sebastian Bach (1685-1750) was a German composer best known for his contributions to Baroque music. Pianist Glenn Gould said,
"The prerequisite of contrapuntal art, more conspicuous in the work of Bach than in that of any other composer, is an ability to conceive a priori of melodic identities which when transposed, inverted, made retrograde, or transformed rhythmically will yet exhibit, in conjunction with the original subject matter, some entirely new but completely harmonious profile." (So You Want to Write A Fugue, 1963)
The rest of this post is some quotes from Bach.

Music and God


"Like all music, the figured bass should have no other end and aim than the glory of God and the recreation of the soul; where this is not kept in mind there is no true music, but only an infernal clamour and ranting." (Quoted in Bibel und Symbol in den Werken Bachs by Ludwig Prautzsch)

"I play the notes as they are written, but it is God who makes the music." (Goodreads.com)

"Music is an agreeable harmony for the honor of God and the permissible delights of the soul." (Goodreads.com)

"The final aim and reason of all music is nothing other than the glorification of God and the refreshment of the spirit." (Goodreads.com)

Meditation


"Ceaseless work, analysis, reflection, writing much, endless self-correction, that is my secret." (AZQuotes.com)

Wilhelm Rontgen and X-rays


Photo source: Wikimedia Commons, Nobel Foundation

Wilhelm Rontgen (1845-1923) was a German physicist best for producing and detecting electromagnetic radiation in a wavelength also known as X-rays. Weapons scientist Otto Glasser said,
"Rontgen was an experimental physicist of the old school and built most of his own equipment... It was Rontgen's custom, when beginning new investigations, to repeat important experiments made previously by others in the same field." (Wilhelm Conrad Rontgen and the Early History of the Roentgen Rays, 1934)
The biographical profile by the Nobel Foundation says,
"Rontgen retained the characteristic of a strikingly modest and reticent man... He was always shy of having an assistant, and preferred to work alone."
Below is one of Rontgen's first X-ray photographs of Albert von Kolliker's hand in 1896. Photo source: Wikimedia Commons


The rest of this of this post is some quotes from Rontgen.

Discovery of X-rays


"Having discovered the existence of a new kind of rays, I of course began to investigate what they would do... It soon appeared from the tests that the rays had penetrative power to a degree hitherto unknown. They penetrated paper, wood, and cloth with ease; and the thickness of the substance made no perceptible difference, within reasonable limits." (The New Marvel in Photography, 1896)

"In a few minutes there was no doubt about it. Rays were coming from the tube which had a luminescent effect upon the paper... It seemed a first a new kind of invisible light. It was clearly something new, something unrecorded." (The New Marvel in Photography, 1896)

"If the hand be held between the discharge-tube and the screen, the darker shadow of the bones is seen within the slightly dark shadow-image of the hand itself." (On a New Kind of Rays, 1895)

"I was working with a Crookes tube covered by a shield of black cardboard. A piece of barium platino-cyanide paper lay on the bench there. I had been passing a current through the tube, and I noticed a peculiar black line across the paper." (The New Marvel in Photography, 1896)

Edward Jenner and vaccinations


Photo source: Wikimedia Commons

Edward Jenner (1749-1823) was an English physician best known for creating the first smallpox vaccination. Wikipedia says,
"Jenner is often called 'the father of immunology' and his work is said to have 'saved more lives than the work of any other human'. In Jenner's time, smallpox killed around 10 percent of the population, with the number as high as 20 percent in towns and cities where infection spread more easily." (Wikipedia: Edward Jenner, 8.21.21 UTC 19:16)
The rest of this post is some quotes from Jenner.

Benefit to mankind


"While the vaccine discovery was progressive, the joy I felt at the prospect before me of being the instrument destined to take away from the world one of its greatest calamities [smallpox], blended with the fond hope of enjoying independence and domestic peace and happiness, was often so excessive that, in pursuing my favourite subject among the meadows, I have sometimes found myself in a kind of reverie." (Quoted in The Life of Dr. Jenner, 1827)

"I shall endeavor still further to prosecute this inquiry, an inquiry I trust not merely speculative, but of sufficient moment to inspire the pleasing hope of its becoming essentially beneficial to mankind." (AZQuotes.com)

"I hope that some day the practice of producing cowpox in human beings will spread over the world - when that day comes, there will be no more smallpox." (AZQuotes.com)

Disease


"The deviation of man from the state in which he was originally placed by nature seems to have proved to him a prolific source of diseases." (Goodreads.com)

Joseph Lister and antiseptics


Photo source: Wikimedia Commons, Weltrundschau zu Reclams Universum

Joseph Lister (1827-1912) was an English surgeon best known for his pioneering work in antiseptic surgery. Physician Clifford Allbutt said,
"Lister saw the vast importance of the discoveries of Pasteur. He saw it because he was watching on the heights, and he was watching there alone." (The Encyclopaedia Britannica, 1911)
Wikipedia says,
"Applying Louis Pasteur's advances in microbiology, Lister championed the use of carbolic acid as an antiseptic, so that it became the first widely used antiseptic in surgery." (Wikipedia: Joseph Lister, 8.21.21 UTC 12:37)
The rest of this post is some quotes from Lister.

Antiseptics


"Bearing in mind that it is from the vitality of the atmospheric particles that all the mischief arises, it appears that all that is requisite is to dress the wound with some material capable of killing these septic germs, provided that any substance can be found reliable for this purpose, yet not too potent as a caustic." (On a New Method of Treating Compound Fracture, 1867)

"But when it has been shown by the researches of Pasteur that the septic property of the atmosphere depended not on the oxygen, or any gaseous constituent, but on minute organisms suspended in it, which owed their energy to their vitality, it occurred to me that decomposition in the injured part might be avoided without excluding the air, by applying as a dressing some material capable of destroying the life of the floating particles. Upon this principle I have based a practice." (On the Antiseptic Principle in the Practice of Surgery, 1867)

Surgery


"If the love of surgery is a proof of a person's being adapted for it, then certainly I am fitted to be a surgeon; for thou can'st hardly conceive what a high degree of enjoyment I am from day to day experiencing in this bloody and butchering department of the healing art." (Letter to his father, 1853)

"It is our proud office to tend the fleshly tabernacle of the immortal spirit, and our path, rightly followed, will be guided by unfettered truth and love unfeigned." (AZQuotes.com)

Gregor Mendel and genetics


Photo source: Wikimedia Commons

Gregor Mendel (1822-1884) was a German biologist best known for his pioneering work on genetics. Biologist David P. Clark said,
"The birth of modern genetics was due to the discoveries of Gregor Mendel (1823-1884), an Augustinian monk who taught natural science to high school students in the town of Brno in Moravia. Mendel's greatest insight was to focus on discrete, clear-cut characters rather than measuring continuously variable properties, such as height or weight. Mendel used pea plants and studied characteristics such as whether the seeds were smooth or wrinkled, whether the flowers were red or white, and whether the pods were yellow or green, etc." (Molecular Biology, 2010)
The rest of this post is some quotes from Mendel.

Traits


"That no generally applicable law of the formulation and development of hybrids has yet been successfully formulated can hardly astonish anyone who is acquainted with the extent of the task and who can appreciate the difficulties with which experiments of this kind have to contend." (Experiments in plant-hybridisation, 1865)

"The striking regularity with which the same hybrid forms always reappeared whenever fertilisation took place between the same species induced further experiments to be undertaken..." (Experiments in plant-hybridisation, 1865)

"Experiments on ornamental plants undertaken in previous years had proven that, as a rule, hybrids do not represent the form exactly intermediate between the parental strains." (Experiments in plant-hybridisation, 1865)

"The course of development consists simply in this; that in each generation the two parental traits appear, separated and unchanged, and there is nothing to indicate that one of them has either inherited or taken over anything from the other." (Letter to Carl Nageli, 1867)

"In this generation, along with the dominating traits, the recessive ones also reappear, their individuality fully revealed, and they do so in the decisively expressed average proportion of 3:1, so that among each four plants of this generation three the dominating and one the recessive characteristic." (Experiments in plant-hybridisation, 1865)

William Harvey and the heart


Photo source: Wikimedia Commons, Daniel Mijtens

William Harvey (1587-1657) was an English physician best known for his analysis of blood circulation. Robert Willis says,
"Harvey was not content merely to gather knowledge; he digested and arranged it under the guidance of the faculties which compare and reason... Harvey appears to have possessed, in a remarkable degree, the power of persuading and conciliating those with whom he cam in contact.
Neuroscientist Robert Willis said,
"Few would have predicted that the discovery of the circulation of the blood woudl have hanged the way philosophers view the world, theologians conceive of God, or astronomers look at the starts, yet all of that happened." (The Fabric of Mind, 1985)
The rest of this post is some quotes from Harvey.

Heart


"This organ deserved to be styled the starting point of life and the sun of our microcosm just as much as the sun deserves to be styled the heart of the world. For it is by the heart's vigorous beat that the blood is moved, perfected activated, and protected from injury and coagulation. The heart is the tutelary deity of the body..." (De Motu Cordis, 1628)

"The blood in the animal body is impelled in a circle and is in a state of ceaseless motion... and that it is the sole and only end of the motion and contraction of the heart." (On the Motion of the Heart and Blood, 1628)

"I finally saw that the blood, forced by the action of the left ventricle into the arteries, was distributed to the body at large, and its several parts, in the same manner as it is sent through the lungs, impelled by the right ventricle into the pulmonary artery, and that it then passed through the veins and along the vena cava, and so round to the left ventricle in the manner already indicated." (Quoted in the Works of William Harvey)

Demonstration


"When in many dissections, carried out as opportunity offered upon living animals, I first addressed my mind to seeing how I could discover the function and offices of the heart's movement in animals through the use of my own eyes instead of through the books and writings of others." (De Motu Cordis, 1628)

"I profess both to learn and to teach anatomy not from books but from dissections; not from positions of philosophers but from the fabric of nature." (Dedication of Dr. Argent and Other Learned Physicians)

Epistemology


"There is no science which does not spring from pre-existing knowledge, and no certain and definite idea which has not derived its origin from the senses." (Quoted in The First Anatomical Disquisition on the Circulation of the Blood by Willis and Bowie)

"The studious and good and true, never suffer their minds to be warped by the passions of hatred and envy, which unfit men duly to weigh the arguments that are advanced in behalf of truth, or to appreciate the proposition that is even fairly demonstrated." (Dedication of Dr. Argent and Other Learned Physicians)

Alexander Graham Bell and the telephone


Photo source: Wikimedia Commons, Moffet Studio

Alexander Graham Bell (1847-1922) was a Scottish inventor and scientist best known for creating the first practical telephone. Wikipedia says,
"[Bell's] research on hearing and speech further led him to experiment with hearing devices which eventually culminated in Bell being award the first U.S. patent for the telephone in 1876... Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils and aeronautics." (Wikipedia: Alexander Graham Bell, 8.21.21 UTC 00:26)
The rest of this quote is some quotes from Bell.

Telegraphy


"Watson... if I can get a mechanism which will make a current of electricity vary in its intensity, as the air varies in density when a sound is passing through it, I can telegraph any sound, even the sound of speech." (AZQuotes.com)

"Grand telegraphic discovery today... Transmitted vocal sounds for the first time... With some further modification I hope we may be enabled to distinguish... the 'timbre' of the sound. Should this be so, conversation viva voce by telegraph will be a fait accompli." (AZQuotes.com)

"The day will come when the man at the telephone will be able to see the distant person to whom he is speaking." (AZQuotes.com)

Discovery


"When I have worked a long time on one thing, I make it a point to bring all the facts regarding it together before I retire." (Interview in How They Succeeded; Bell Telephone Talk, 1901)

"Concentrate all your thoughts upon the work at hand. The sun's rays do not burn until brought to a focus." (Interview in How They Succeeded; Bell Telephone Talk, 1901)

"You cannot force ideas. Successful ideas are the result of slow growth. Ideas do not reach perfection in a day no matter how much study is put upon them." (Interview in How They Succeeded; Bell Telephone Talk, 1901)
