Let me start with my conclusions: like most other philosophers of his era, Spinoza did not have well-developed views on consciousness and its place in the mind. Somewhat paradoxically, however, a basic tenet of his metaphysics generated a problem which might have been solved if he had thought more about those issues. So in the end, then, Spinoza did not have much to say about consciousness even though the coherency or at least the plausibility of his system demanded it.
