Scottish realism

Scottish Common Sense Realism, also known as the Scottish School of Common Sense, is a school of philosophy that originated in the ideas of Scottish philosophers Thomas Reid, Adam Ferguson, James Beattie, and Dugald Stewart during the 18th century Scottish Enlightenment. Reid emphasized man's innate ability to perceive common ideas and that this process is inherent in and interdependent with judgement. Common sense therefore, is the foundation of philosophical inquiry. Though best remembered for its opposition to the pervasive philosophy of David Hume, Scottish Common Sense philosophy is influential and evident in the works of Thomas Jefferson and late 18th century American politics.

The Scottish School of Common Sense was an epistemological philosophy that flourished in Scotland in the late 18th and early 19th centuries. Its roots can be found in responses to the writings of such philosophers as John Locke, George Berkeley and David Hume, and its most prominent members were Dugald Stewart, Thomas Reid and William Hamilton. Philosophically, Scottish Realism served as a rebuttal to scepticism while keeping with the influential teachings of Isaac Newton and Francis Bacon. While largely understated for many years, the influence it had on philosophers elsewhere in Europe, not to mention in the United States, is of a considerable magnitude.

One central concern of the school was to defend "common sense" against philosophical paradox and scepticism. It argued that common-sense beliefs govern the lives and thoughts even of those who avow non-commonsensical beliefs and that matters of common sense are inherent to the acquisition of knowledge. The qualities of its works were not generally consistent; Edward S. Reed writes, e.g., "[Whereas] Thomas Reid wished to use common sense to develop philosophical wisdom, much of this school simply wanted to use common sense to attack any form of intellectual change."
