In this classic work, Descartes first defines what is known for certain, and then builds on it to what can be known. He differed from the later empiricists in that he believed people are not born with their minds as a blank slate, or tabula rasa, but are born with certain innate knowledge, including the knowledge of the existence of God and of the difference between right and wrong. This book is presented in its original Latin text, followed by the English text.
Ren? Descartes, known as the Father of Modern Philosophy and inventor of Cartesian coordinates, was a seventeenth century French philosopher, mathematician, and writer. Descartes made significant contributions to the fields of philosophy and mathematics, and was a proponent of rationalism, believing strongly in fact and deductive reasoning. Working in both French and Latin, he wrote many mathematical and philosophical works including The World, Discourse on a Method, Meditations on First Philosophy, and Passions of the Soul. He is perhaps best known for originating the statement I think, therefore I am.
