Thomas Reid (1710-1796) was a Scottish philosopher best known for his contributions to Scottish Enlightenment. Wikipedia says,
"Reid believed that common sense (in a special philosophical sense of sensus communis) is, or at least should be, at the foundation of all philosophical inquiry. He disagreed with Hume, who asserted that we can never know what an external world consists of as our knowledge is limited to ideas in the mind, and George Berkeley, who asserted that the external world is merely ideas in the mind."
