Augggh! Descartes philosophy is crap! And very non-Catholic!
You’re right — but he wasn’t wrong about everything. He was right about the subjective nature of sensory perception , for example. One needn’t buy the whole loaf when a slice is enough.
Skepticism is common amounf young atheists: “Eff Ah cain’t poke et with a stick, et ain’t real” is their credo. Descartes took skepticism as far as it could go, and found himself face to face with the Almighty. While I do not subscribe to the philosophy of Descartes in toto, his status as a doubter who found God makes him an excellent example for modern-day doubters.
