Recently finished Leibniz' Monadology. It sucked. It was nice though, because right after finishing it, I read Julien Jean Offray de La Mettrie's L'Homme Machine, in which he said as much about Leibniz' idea of monads as well. He said it was incoherent, which is exactly how I felt. As for La Mettrie, I really enjoyed it. I didn't expect to enjoy reading an 18th century materialist philosopher, but he managed to hook me. In short, La Mettrie argued that all things are caused materially and at one point alludes to the theory that is now common in cognitive neuroscience: that things mental arise from brain states. La Mettrie admits that this seems at some level to be incompatible with material functionality, but holds out hope that it will be figured out one day. I will probably go back and revisit it, but La Mettrie's concept of Natural Law pretty much resembles Darwin's Theory of Evolution in terms of species propagation. In some sense, this makes La Mettrie an amoralist, because he doesn't take any morality seriously unless it concerns survival of some sort. Pretty fascinating stuff to say the least.
Right now I'm reading two books. Gerauld de Cordemoy's Discours physique de la parole and Alice Dreger's Galileo's Middle Finger: Heretics, Activists, and One Scholar's Search for Justice.
