Why does so much philosophy seem so unscientific?

For example, Spinoza and Berkeley's Metaphysics and Epistemology just seem like people making claims and following those claims logically, but without any evidence. The ideas of substance and of God and modes just seem like an arbitrary way of organizing things without any proof.

Spinoza fucking loved contemporary sciences and heavily advocated for people to study them. The issue is that you're ignoring their historical place. The sciences were totally bound up with the rest of philosophical investigation, which included things like God. Things like "substance" were just ways of discussing things that exist, and even today there are people who defend the Aristotelian metaphysics from which all this language comes from. The modern "scientific" point of view that you're taking from granted was actually something that slowly developed from the work of these very philosophers. There is no way that we have Kant without Descartes and Spinoza.

There's nothing unscientific about it. You're just looking at the people who built the world that you live in from the point of view of already living in it instead of building it.
