Spinoza's Ethics: I.A2: Knowing

This axiom seems like a companion to 1.A1 in the way of Spinoza's parallelism of the mind and the body. One key question is whether this parallelism is employing "a view from nowhere" or "a view from somewhere." The verb used here is "conceive" or concipi which typically signifies a "view from nowhere." It may be that this is irrelevant as an axiom because Spinoza is simply outlining the operation of logic rather than content as in the definitions. If so, it would make sense to use the "view from nowhere" verbs, but not be pointing to substance versus attributes.

Id quod per aliud not potest concipi, per se concipi debet.

Translated as,

That which cannot be conceived through another, must be conceived through itself.
