Thomas Reid was a Scottish philosopher in the 18th century who is known for his contributions to the fields of epistemology and moral philosophy. Some synonyms for his name include: Scottish philosopher, Reid of Kincardine, 18th-century philosopher, founder of Scottish common sense philosophy, and moral sense philosopher. Reid's ideas centered around the idea that our knowledge is based on our senses and observations, and that we have innate faculties that allow us to perceive the world accurately. He also believed that morality is based on our natural sentiments and feelings, rather than on abstract reasoning or utilitarian calculations. Reid's work has had a profound influence on subsequent philosophers, particularly in Scotland, and his ideas continue to be debated and discussed today.
