This brief text assists students in understanding Peirce's philosophy and thinking so they can more fully engage in useful, intelligent class dialogue and improve their understanding of course content. Part of the Wadsworth Notes Series, (which will eventually consist of approximately 100 titles, each focusing on a single "thinker" from ancient times to the present), ON PEIRCE is written by a philosopher deeply versed in the philosophy of this key thinker. Like other books in the series, this concise book offers sufficient insight into the thinking of a notable philosopher, better enabling students to engage in reading and to discuss the material in class and on paper.
We gain knowledge, not merely by reasoning, but by learning from our mistakes. Knowledge, therefore, is to be had at the end of the journey, not the beginning. If we gain knowledge from learning from our mistakes, then we must never believe anything, that if we were mistaken, we would still believe it anyway. We must always check our beliefs with reality. The great enemy of science is religion, because when the choice comes to choose between reality and religion, many people choose religious dogma and discard reality.
