Skeptic Skepticism

By attempting to discard everything that he had believed to be true, Descartes was left with out a foundation to base any future principles on. This dilemma lead him to the conclusion, "I think, therefore I am." After reading Descartes, I find myself skeptical of all knowledge. Due mostly to the fact that knowledge derives from human observation and thought. Perceptions and "truths" vary widely between individuals. The "facts" that are accepted as true are constantly changing as knowledge advances. Therefore, I can really only know that "I am," but I cannot know for certain about anything else.
