A History of Philosophy

by Wilhelm Windelband

1898

Three tasks direct the author's work: to establish from available sources the circumstances in life, the mental development, and the doctrines of individual philosophers; to reconstruct from these facts the "genetic" process, so that the effect of these factors upon each philosopher's doctrine can be determined; to determine the overall value in the history of philosophy of the doctrines considering their origin.
