Lift is not a noun. Maybe the reference goes back to something Plato said through Socrates, or again, in set theory, A thing is a thing because it is a member of a class, meaning that definition determines class membership.

However, this is a fine point we don't often think about. We be rusty thinkers. I would think that a plane flys, because of available air, or material by which it may be lifted--but this would be wrong too, a definition includes not only material difference but form as well, air and velocity by which lift may be created. One is actually creating a solid through the use of velocity.

Lift is a noun and a verb. Check a dictionary.

Read Parminides, what happens to logic when you have the same name for different parts of speech. Is logic even possible. There are only three primitive categories of names, Names for things, and the names of a things two elements, or possible abstractions, form and material difference. Give any two, or all three the same name, and you are often speaking gibberish without knowing it.

That piece was meant to get the reader to start thinking about the principles of predication. A lift is not lift.
