FAQ
Frequently Asked Questions

Think of 'Cartesian' as 'Artisan of the Cart' (Des-Cart-es). An artisan creates precise, deliberate works, just as Descartes created a precise, deliberate system of thought based on a grid (coordinates) of doubt.
Conceptual Metaphor
THOUGHT IS GEOMETRY / THE MIND IS A MACHINE (Cartesian philosophy often treats reasoning as a geometric proof and mental operations as mechanical).
