P32: Insofar as men are subject to passions, they cannot be said to agree in nature.

Dem.: Things that are said to agree in nature are understood to agree in power (by IIIP7), but not in lack of power, or negation, and consequently (see IIIP3 S) not in passion either.

So insofar as men are subject to passions, they cannot be said to agree in nature, q.e.d.

Schol.: This matter is also evident through itself. If someone says that black and white agree only in this, that neither is red, he affirms absolutely that black and white agree in nothing. Similarly, if someone says that a stone and a man agree only in this, that each is finite, lacks power, does not exist from the necessity of its nature, or, finally, is indefinitely surpassed by the power of external causes, he affirms completely that a stone and a man do not agree in anything. For things that agree only in a negation, or in what they do not have, really agree in nothing.
