René Descartes — EEBO-TCP A35745, keyed from the English translation of 1649, the first.
The Discours de la méthode of 1637, in the English of 1649: the story of how Descartes came to doubt everything he had been taught and what he found he could not doubt. The fourth part is the first form of the argument of the Meditations — I think, therefore I am, and from the idea of a perfect being to the existence of God — and the fifth draws the line between the soul of man and the machinery of the beasts.
