Why should rich people pay more taxes?


In the United States, I believe rich people should pay more taxes because there are too many neglected public services. This post is a follow up for an earlier post I did on reason. For this post I tried to weave together a web of concepts to support my position. There are 34 quotes divided into 8 sections:

A. Raising taxes on rich people will not hurt economic growth (4)
B. Rich people have accumulated an unprecedented amount of wealth (4)
C. Government finance must be audited to ensure transparency (3)
D. We should invest in building a strong middle class (5)
E. We should support our most vulnerable citizens (4)
F. Single-payer healthcare is the best solution (5)
G. We should accelerate innovation in critical technologies (4)
H. Public foreign aid is the best foreign policy (5)

A. Raising taxes on rich people will not hurt economic growth


Thomas Hungerford (economist)
1. "The results of the analysis suggest that changes over the past 65 years in the top marginal tax rate and the top capital gains tax rate do not appear correlated with economic growth [in the United States]. The reduction in the top tax rates appears to be uncorrelated with saving, investment, and productivity growth. The top tax rates appear to have little or no relation to the size of the economic pie." (Taxes and the Economy: An Economic Analysis of the Top Tax Rates Since 1945, 2012)

Gwynn Guilford (journalist)
2. "Cutting taxes on America's rich isn't going to encourage them to invest more - they already have plenty to spend and aren't spending it. Worse, by shifting wealth from middle class families to the moneyed few - a group that is able to consume far less than the working masses - this sort of policy suppresses consumption, which in turn discourages investment in productive businesses." (Almost everything Republicans get wrong about the economy started with a cocktail napkin in 1974, 2017)

Alana Semuels (journalist):
3. "[In the United States] between 1935 and 1982, the top tax rate did not dip below 70 percent. Part of this was due to a belief among those in charge that government had a role in combating extreme wealth." (Is the U.S. Due for Radically Raising Taxes for the Rich? 2016)

Thomas Hungerford (economist)
4. "The top marginal rate in the 1950s was over 90 percent and the real GDP growth rate averaged 4.2 percent and the real per capita GDP increased annually by 2.4 percent in the 1950s." (Taxes and the Economy: An Economic Analysis of the Top Tax Rates Since 1945, 2012)

B. Rich people have accumulated an unprecedented amount of wealth


Bernie Sanders (1941-now, politician):
5. "How many times have you heard the refrain, 'America is broke'? Baloney... in reality, we are the richest country in the world, and we are richer than at any other time in history. The U.S. has a record-breaking $88 trillion in total wealth... " (Our Revolution, 2016)

Bernie Sanders (1941-now, politician):
6. "In 1979, the top one-tenth of 1 percent owned about 7 percent of the wealth in this country. Now it owns 22 percent." (Our Revolution, 2016)

John Kenneth Galbraith (1908-2006, economist):

Simone Campbell (1945-now, lawyer):
8. "Hard-working people are trying their best, but those who hold on to capital are not sharing the wealth, and there is the problem." (Interviewed by Al Sharpton on Media Matters for America, 2014)

C. Government finance must be audited to ensure transparency


Henry George (1839-1897, economist)
9. "To prevent government from being corrupt and tyrannous, its organization and methods should be as simple as possible... and in all its parts it should be kept as close to the people as directly within their control as may be." (Social Problems, 1883)

Louis Brandeis (1856-1941, lawyer)
10. "Publicity is justly commended as a remedy for social and industrial disease. Sunlight is said to be the best of disinfectants; electric light the most efficient policeman." (Other People's Money - And How Bankers Use It, 1914)

James Madison (1751-1836, 4th President of the United States)
11. "If men were angels, no government would be necessary. If angels were to govern men, neither external nor internal controls on government would be necessary." (Federalist No. 51, 1788)

D. We should invest in building a strong middle class


Barack Obama (1961-now, 44th President of the United States):
12. "We don't just want everyone to share in America's success, we want everyone to contribute to our success." (State of the Union Address, 2015)

Barack Obama (1961-now, 44th President of the United States):
13. "In a global economy, a country's greatest resource is its people. So by investing in you, this nation can open the door for far more prosperity - because unlocking a nation's potential depends on empowering all its people, especially it's young people." (Yangon University Speech, 2012)

Bernie Sanders (1941-now, politician):
14. "According to a 2007 report by the Federal Revere Bank of Minneapolis, 'The most efficient means to boost the productivity of the workforce 15 to 20 years down the road is to invest in today's youngest children.'" (Our Revolution, 2016)

Bernie Sanders (1941-now, politician):

E. We should support our most vulnerable citizens


Bernie Sanders (1941-now, politician):

Bernie Sanders (1941-now, politician):
18. "When people become old, they often become frail and sick. They are unable to work and earn an income. In a civilized society, the older generation - the people who raised us - are entitled, and allowed, to live out their remaining years in dignity and security." (Our Revolution, 2016)

Hillary Clinton (1947-now, politician):
19. "Look at the budget that was just proposed in Washington. It is an attack of unimaginable cruelty on the most vulnerable among us, the youngest, the oldest, the poorest, and hard working people who need a little help to gain or hang on to a decent middle class life." (Wellesley commencement speech, 2017)

Bernie Sanders (1941-now, politician):
20. "Study after study has shown that without stable housing it is much harder for working people to hold down jobs and get the health care they need, and children are put at a profound disadvantage in terms of intellectual and emotional development and school performance... Decent-quality affordable housing should be a right of all Americans." (Our Revolution, 2016)

F. Single-payer healthcare is the best solution


Bernie Sanders (1941-now, politician):

G. We should accelerate innovation in critical technologies


Bernie Sanders (1941-now, politician):
26. "This is the stuff we do so well when challenged as a nation, whether by putting a man on the moon, eradicating diseases, or developing the Internet. The U.S. can and must dedicate our engineering know-how to a clean energy revolution, in our universities, in our national energy labs, and in businesses and communities all across the country." (Our Revolution, 2016)

Bill Gates (1955-now, businessman):

What is science? (2nd attempt)


In an earlier post, I tried to define the word 'science', but I now disagree with my previous definition. Here is my previous definition:
Science is the systematic analysis of reality
I believe this definition is too broad to accurately capture the concept of 'science'. There are many types of systematic analyses that do not qualify as science. For example, a telephone bill statement which has many statistics, allows you to systematically analyze your telephone usage, but intuitively we know this is not science. Another example is systematically analyzing baseball player statistics, but intuitively we also know this not science. Here is my new definition:
Science is knowledge established through controlled experiments and verification
When people talk about science, I believe this is what they are talking about. This definition does not create a strict boundary between science and non-science because in my opinion the word 'controlled' is subjective. For some experiments, controlling every variable is impossible.

Is economics a science? For the most part I believe the answer is no. I think the closest thing we have to controlled experiments in economics is quasi-experimental analyses which look at real world events that resemble controlled experiments. But the problem with these analyses is that are there's always too many confounding variables that could distort results. In the real world, every economic event is affected by countless factors. I can't imagine how a researcher can be sure that every potential confounding variables is controlled even with statistical techniques.

The rest of this post is a collection of definitions of science from philosophers and dictionaries.

Definitions of science from philosophers


Karl Popper (1902-1994)
1. "...statements or systems of statements, in order to be ranked as scientific, must be capable of conflicting with possible, or conceivable observations." (Conjectures and refutations. The growth of scientific knowledge, 1962)

Thomas Kuhn (1902-1996)
2. "...the role in scientific research of what I have since called 'paradigms'. These I take to be universally recognized scientific achievements that for a time provide model problems and solutions for a community of practitioners." (The Structure of Scientific Revolutions, 1962)

Paul Feyerabend (1924-1994)
3. "...the separation of science and non-science is not only artificial but also detrimental to the advancement of knowledge. If we want to understand nature, if we want to master our physical surroundings, then we must use all ideas, all methods, and not just a small selection of them." (Against method, 1975)


Larry Laudan (1941-now)
4. "...there is no demarcation line between science and non-science, or between science and pseudo-science, which would win assent from a majority of philosophers. Nor is there one which should win acceptance from philosophers or anyone else." (The Demise of the Demarcation Problem, 1983)


Paul Thagard (1950-now):
5. "A theory of disciplines which purports to be scientific is pseudoscientific if and only if it has been less progressive than alternative theories over a long period of time and faces many unsolved problems; but the community of practitioners makes little attempt to develop the theory towards solutions of the problems, shows no concern for attempts to evaluate the theory in the relation to others and is selective in considering confirmation and disconfirmation." (Quoted in Science Education by John Gilbert)

William Cecil Dampier (1867-1952)
6. "[Science is] ordered knowledge of phenomena and of the relations between them." (Wikipedia)

Marshall Clagett (1916-2005)
7. "[Science is] first the orderly and systematic comprehension, description and/or explanation of natural phenomena and secondly, the mathematical and logical tools necessary for the undertaking." (Wikipedia)

David Pingree (1933-2005)
8. "Science is a systematic explanation of perceived or imaginary phenomena or else is based on such an explanation. Mathematics finds a place in science only as one of the symbolical languages in which scientific explanations may be expressed." (Wikipedia)

B. The right combination of concepts fit together to infer a proposition (3)
C. It's impossible to 100% prove or disprove a proposition (4)
D. Controlled experiments are the best evidence (4)
E. Disagreements are impossible to resolve when people are not being clear about the proposition and the evidence they are using (4)

A. Sensory experience is the source of all evidence

2. "All our knowledge falls within the bounds of experience." (Critique of Pure Reason, 1781)

Democritus (460-370 BC, philosopher):
3. We know nothing accurately in reality, but [only] as it changes according to the bodily condition, and the constitution of those things that flow upon [the body] and impinge upon it." (Wikiquote)

B. The right combination of concepts fit together to infer a proposition


Rene Descartes (1596-1650, philosopher):
4. "Each problem that I solved became a rule, which served afterwards to solve other problems." (Discourse on Method, 1637)

5. "Verification in science is not, however, of single statements but of the entire system or a sub-system of statements." (The Unity of Science, 1934)

Ludwig Wittgenstein (1889-1951, philosopher):
6. "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)

C. It's impossible to 100% prove or disprove a proposition


Rene Descartes (1596-1650, philosopher):
7. "In order to seek truth, it is necessary once in the course of our life, to doubt, as far as possible, of all things." (Principles of Philosophy, 1644)

10. "I weigh the one miracle against the other; and according to the superiority, which I discover, I pronounce my decision and always reject the greater miracle." (An Enquiry Concerning Human Understanding, 1748)

D. Controlled experiments are the best evidence


Rudolf Carnap (1891-1970, philosopher):
11. "One of the principal tasks of the logical analysis of a given proposition is to find out the method of verification for that proposition." (Philosophy and Logical Syntax, 1935)

Claude Bernard (1813-1878, physiologist):
14. "Indeed, proof that a given condition always precedes or accompanies a phenomenon does not warrant concluding with certainty that a given condition is the immediate cause of that phenomenon. It must still be still established that when this condition is removed the phenomenon will no longer appear." (Introduction a l'Etude de la Medecine Experimental, 1865)

E. Disagreements are impossible to resolve when people are not clear about the proposition and the evidence they are using

What is art?


What is art? This is not an easy question. In our daily lives, sometimes it's difficult to differentiate what is art from non-art. How much of the human experience is art? Here is my definition:
Art is a creation that has aesthetic qualities or surreal qualities or portrays real world objects and phenomena
This is not a precise definition because the words 'aesthetic' and 'surreal' are subjective. Aesthetics has to do with the appreciation of beauty. Surreal has to do with the unreal and bizarre. I believe these three types of art (aesthetic, surreal and portrayal) create an accurate definition for the word 'art'. This definition does not apply to the craft interpretation for the word 'art' (for example, the art of investing).

The rest of this post is a collection of definitions of art from dictionaries.

6. "The idea that in order to get clear about the meaning of a general term one had to find the common element in all its applications has shackled philosophical investigation; for it has not only led to no result, but also made the philosopher dismiss as irrelevant the concrete cases, which alone could have helped him understand the usage of the general term."

What is science?

 

(Update: I have revised my definition of science in a more recent post. In this post, I explain the flaws with the definition provided below)

What is science? This is a very hard question. Many philosophers have tried to establish their own criteria to separate science from non-science. The problem with the word 'science' is everyone has their own internal idea of what this word should mean. Here is my definition:
Science is the systematic analysis of reality
This is not a precise definition because the word 'systematic' is subjective. One could even argue that all language and sentence structure is systematic therefore any statement could be considered scientific. Therefore, I believe drawing a strict boundary is impossible between science and knowledge. But I still think it's important to place meaning to the word 'science' because it articulates a particular type of knowledge. The concept of science is a real thing and deserves its own word.

Many people think that science has to do with proven facts. I disagree with this for two reasons. First, the word 'fact' creates too of high of a standard for what science is. I philosophically believe there are no proven facts (except the cogito). For example, you cannot be 100% be sure that the sun will come up tomorrow because there could be a supernova or black swan event. Second, science is more of a process than a finished product. By limiting science to only facts, a person in lab testing unproven theories is not doing science. Instead, we should think of science as trying to paint a detailed picture of reality.

Where does astrology fit into my definition? Astrology does not qualify as science because it is incompatible with much of the existing evidence we already know about reality. As long as an endeavor is oriented toward explaining reality in a systematic manner, I believe it qualifies as a science.

The rest of this post is a collection of definitions of science from philosophers and dictionaries. I agree most with the definitions provided by Paul Feyerabend and Larry Laudan.

Definitions of science from philosophers


Karl Popper (1902-1994)
1. "...statements or systems of statements, in order to be ranked as scientific, must be capable of conflicting with possible, or conceivable observations." (Conjectures and refutations. The growth of scientific knowledge, 1962)

Thomas Kuhn (1902-1996)
2. "...the role in scientific research of what I have since called 'paradigms'. These I take to be universally recognized scientific achievements that for a time provide model problems and solutions for a community of practitioners." (The Structure of Scientific Revolutions, 1962)

Paul Feyerabend (1924-1994)
3. "...the separation of science and non-science is not only artificial but also detrimental to the advancement of knowledge. If we want to understand nature, if we want to master our physical surroundings, then we must use all ideas, all methods, and not just a small selection of them." (Against method, 1975)


Larry Laudan (1941-now)
4. "...there is no demarcation line between science and non-science, or between science and pseudo-science, which would win assent from a majority of philosophers. Nor is there one which should win acceptance from philosophers or anyone else." (The Demise of the Demarcation Problem, 1983)


Paul Thagard (1950-now):
5. "A theory of disciplines which purports to be scientific is pseudoscientific if and only if it has been less progressive than alternative theories over a long period of time and faces many unsolved problems; but the community of practitioners makes little attempt to develop the theory towards solutions of the problems, shows no concern for attempts to evaluate the theory in the relation to others and is selective in considering confirmation and disconfirmation." (Quoted in Science Education by John Gilbert)

William Cecil Dampier (1867-1952)
6. "[Science is] ordered knowledge of phenomena and of the relations between them." (Wikipedia)

Marshall Clagett (1916-2005)
7. "[Science is] first the orderly and systematic comprehension, description and/or explanation of natural phenomena and secondly, the mathematical and logical tools necessary for the undertaking." (Wikipedia)

David Pingree (1933-2005)
8. "Science is a systematic explanation of perceived or imaginary phenomena or else is based on such an explanation. Mathematics finds a place in science only as one of the symbolical languages in which scientific explanations may be expressed." (Wikipedia)

E. Language is the foundation of knowledge (9)
F. Nature is the perfect model (7)
