Introduction

The six Latin meditations appeared in Paris in 1641, together with objections that Marin Mersenne had collected from scholars, among them Hobbes, Arnauld and Gassendi, and Descartes’s replies; the second edition (Amsterdam, 1642) added a seventh set. The text is written as a sequence of six days of meditation in the first person, which readers are invited to follow. Key steps include the evil deceiver in the first meditation, the piece of wax in the second, the proof of God from the idea of the infinite in the third and the real distinction between mind and body in the sixth. Arnauld’s objection that Descartes argues in a circle is known as the “Cartesian circle”.
