This chapter looks at Descartes' Meditations on First Philosophy as a guide to meditation on God. Descartes' Meditations on First Philosophy embodies a conception of philosophy that is deeply anti-scholastic and anti-analytic. From the perspective of the meditation on God, the purpose of the First Meditation is to introduce the meditative object. The meditator reflects on the actual or even just merely possible existence of this entity, this "supreme fountain of truth". The meditator perceives God as "a perfect being who is already wholly present though never wholly grasped by the human mind". Meditation on God will transform the meditator as it displays its infinite, ultimately fulfilling, object. If the Meditations are read as an essay engaged in refuting skepticism and securing the foundations of science, the quasi-mystical rapture at the end of the third Meditation is surely most surprising.
