GLOSSARY 47 
nature, or the adequation of the thing to the intellect and

vice-versa. 
Unity, Substantial: Unum per se That which is one by virtue

of its proper or intrinsic operation. It is opposed to unum

per accidens or one by accident. A substantial unity is one

by virtue of the operation by which it exists necessarily.

An accidental unity is one merely by conjunction as the

parts of an aggregate. Per se: brought into existence by

a proper act, but indicating a measure of dependence from

God.
