Started reading Spinoza's Ethics 2 days ago, and it has gone well so far. However, even with its definition at the start of Book II, I struggle to understand Spinoza's use of singular things in propositions after prop. 8.
In most of the demonstrations he uses argumenation along the lines of "Singular things are not in god's essence as they are not infinite, and hence neither in the essence of his attributes (as they are also their own cause and have necessary existence). Therefore man doesn't have necessary existence being a singular thing" However, I don't quite understand how singular things can still be, aka. be in god.
My confusion: Since modes are affects of god's attributes they must exist and be infinite. However, can a mode of a mode, or affect of a mode that is infinite be finite since the mode isn't a direct link of substance/god? Is that how singular things come to be? But since god is all encompassing, why aren't these then in his essence, and then have to be necessarily infinite and existant? How can they be "outside" god if god is the only substance, aka. all that is?
Clearly I'm getting something wrong, so any help would be appreciated!
