Descartes

1596 – 1650 · Rationalists · The rationalists & empiricists · 3 works

One man decided that almost everything he believed had come to him secondhand (from teachers, from books, from his own unreliable eyes), and that none of it had ever been checked. So he resolved to tear the whole structure down to the ground, doubt everything it was possible to doubt, and see whether a single certainty was left standing in the rubble that he could build on. He found one. The rest of his life, and most of modern philosophy after him, is the attempt to rebuild a world on that one stone, and the discovery that the stone may not be big enough to hold the house.

Before
