In these actual meanings we do not have to mention why they are restricted. The accidental supposition of the term ' man ' in our proposition causes the term to denote not necessarily all men. And the accidental supposition of the term ' aerial being ' in our proposition, causes the term to denote not all aerial beings.
And it is what the (selected) individual men essentially are, and what the (selected) aerial beings as aerial essentially are, that counts with respect to the truth or falsity of our proposition.
