Ethics

Spinoza's *Ethics* is the kind of book that reinforces comfortable myths about reason and its power. It's honest, rigorous work, but it doesn't fully commit to the moral courage of genuine philosophy. It's more like a mathematical proof than a challenge to how we see the world. In his definitions, Spinoza argues that substance is something that 'exists in itself' and is 'conceived through itself.' He then builds his entire system around this idea, using cold, logical rigor to argue that thinking and extended are one and the same substance. It's brilliant in its way, but it feels more like mathematics than philosophy. This is not a book that changes how you see the world—it doesn't have the moral courage of something like Nietzsche or even Machiavelli. But it is worth engaging with, if only to see how someone could actually believe in reason without flinching.
