Ol and Val tackle the first half of Meditation 3

Exploring the second of Descartes' Meditations, during which the Rene pulls a fast one and uncovers the famous cogito as his rock of certainty - "I think therefore I am" - although not quite in those words, and in which he ransacks the corners ...

Ol, Val and their special guest, Eva, try out Descartes' spiritual exercise of radical doubt - in Meditation 1 - recount some odd dreams and show people how to try this all out at home.

Ol and Val try to make sense out of the first three parts of Descartes' Discourse on the Method, and wonder when Val will get his own valet for his road trip.
