the assertion of an identity of being amounts to something more than a mere identity of connection; so that it appears likely that connection already involves something more than order. And indeed, identity of connection means not only the autonomy of corresponding series, but an isonomy, that is, an equality of principle between autonomous or independent series.

When Spinoza asserts that modes of different attributes have not only the same order, but also the came connection or concatenation, he means that the principles on which they depend are themselves equal.

[The points of a curve are not linked together (concatenantur) in the same way as those of a straight line.]

By his strict parallelism Spinoza refuses any analogy, any eminence, any kind of superiority of one series over another, and any ideal action that presupposes a preeminence: there is no more any superiority of soul over body, than of the attribute of Thought over that ofExtension.

identity seems to be based on what we choose or happen to ignore.
