R. Descartes

These are Descartes 'meditations' on metaphysics which, in my opinion, serve as a splendid example of how geometricians should be more careful when dabbling in metaphysics...if they dare do so at all. If you are a bible-pounder, you will want to read this book; it is chock-full of intransigent circular arguments that are a must have in any conservative Christian's arsenal against the horrors of atheism. It is an important text to read, but aside from the nearly tautological significance of 'cogito, ergo sum', is why I shy away from syllogistic logic. A warning to those lacking a penchant for genuflection towards anything remotely pope-ish, the "Letter of Dedication" may make you physically sick. Still...it's certainly one of those things you must read.
