Which, as I have showed in another place, are combinations of ideas, which the mind, by its free choice, puts together, without considering any connexion they have in nature.

And hence it is, that in all these sorts the ideas themselves are considered as the archetypes, and things no otherwise regarded, but as they are conformable to them.

So that we cannot but be infallibly certain, that all the knowledge we attain concerning these ideas is real, and reaches things themselves.

Because in all our thoughts, reasonings, and discourses of this kind, we intend things no further than as they are conformable to our ideas.

So that in these we cannot miss of a certain and undoubted reality.
