[The Eschaton]

I want to start a discussion about Spinoza. I had recently started reading Ethics and i found myself interested in his writings because the philosophy seems pretty coherent and in good agreement with a modern understanding of the world. I am confused because sometimes i dont follow his arguments very well. In fact sometimes i agree more with his conclusions than his arguments.

His philosophy in part I seems to imply all possible things must exist. It is sort of close to modern cosmology.

His philosophy if the mind i cant tell. Sometimes he seems very dualist but then he also seems very insistent on the embodied mind. Im pretty sure he thinks the mind and body are the same thing but he does also divide the world in two, thought and extension.

His idea of free will seems to be modern compatabalist?

I know some of physics, cosmology, and neuroscience but almost nothing about psychology. I think his philosophy fits very well with what i know of physics, cosmology and modern theory of the mind. Im not sure if his theory of ethics, and human motivation, desire and endeavor is in line with modern understanding.

Do you think Spinoza's arguments are logical, coherent, sound?

How does Spinoza's arguments agree or disagree with scientific understanding?
