Radical forms of philosophical skepticism deny that knowledge or rational belief is possible and urge us to suspend judgment on many or all controversial matters. In Reid's view, such common-sense beliefs are foundational and require no proof in order to be rationally justified.[14] Not long after Hume's death, the great German philosopher Immanuel Kant (1724–1804) argued that human moral awareness makes no sense unless we reject Hume's skeptical conclusions about the existence of God, the soul, free will, and an afterlife. ./cache/en-wikipedia-org-8883.html ./txt/en-wikipedia-org-8883.txt
