descartes past masters took quite a bit of mental power to read but was very worth it. what stood out was how metaphysics and science were closely connected. i found it almost funny that he claimed to have done “nothing” for nine years but converse with people, but i'm sure it tremendously influenced his system of thought, specifically the demon concept. i honestly hope he's correct about everything. there are many other topics i wont be listing but explaining senses, terrestrial bodies, souls, and the structure of the universe to a seventeenth century audience seems unimaginable to me. it's also impressive that he was mindful of how the church would perceive his work while still pushing boundaries. although his descriptions can be obscure, i was still following most of what i read. the points in the book support my understanding of reality since i'm big on innate abilities already. all in all, i thoroughly enjoyed this one and mostly because i couldn't find anything problematic (as far as i can understand).
