Descartes: starting with doubt for a more complete formal presentation of this foundational experience, we must turn to the meditationes de prima philosophia ( meditations on first philosophy ) (1641), in which descartes offered to contemporary theologians his proofs of the existence of god and the immortality of the human soul. As a second proof of god's existence, descartes [1641a: 103f] utilised a form of the traditional ontological argument mackie [1982: 41–9] provides convincing objections against descartes's formulation, drawing on kant's analysis and the concept of existential quantification.
