Spinoza's parallelism embodies in many ways a deeply anti-Cartesian view. By keeping the causal chains of modes of extension somehow separate from the causal chains of modes of thought, Spinoza is guided by his overarching denial of any explanatory connections between the mental and the physical, i. e. of connections of the kind that Descartes, in his account of mind-body interaction, quite happily embraces. But precisely because Spinoza separates the causal chains in this way, there might be thought to be a crucial point of agreement between Descartes and Spinoza on the nature of mind-body relations.

I think that one who appreciates the fact that, if there are to be genuine causal connections, they must amount to conceptual connections, is Hume. Hume, of course, denies that there are conceptual connections among distinct things and so he is unable to come up with genuine cases of causation. But, in a way, Hume does accept the rationalist demand that, if there is to be genuine causation, it must amount to conceptual connection. Spinoza accepts this rationalist demand too. But, unlike Hume, he sees there as being genuine conceptual connections, i. e. causal connections, in the world.

For Spinoza, what it is for a body to be my body is simply that my mind represents that body. And, as we have seen, what it is for an idea to represent a body is for the idea to represent the body's place in a causal network, i. e. for the idea to be the explanation of the body in thought. This is another twofold use of the PSR. The mineness of my body must be explained, and it is explained in terms of the notion of representation and ultimately of explanation itself.
