far as it is considered in itself, without relation to the
object, has all the properties or intrinsic marks of a true idea.
Explanation.-I say intrinsic, in order to exclude that mark
which is extrinsic, namely, the agreement between the idea and
its object (ideatum).

DEFINITION V. Duration is the indefinite continuance of
existing.
Explanation.-I say indefinite, because it cannot be
determined through the existence itself of the existing thing, or
by its efficient cause, which necessarily gives the existence of
the thing, but does not take it away.

DEFINITION VI. Reality and perfection I use as synonymous terms.

DEFINITION VII. By particular things, I mean things which are
finite and have a conditioned existence ; but if several
individual things concur in one action, so as to be all
simultaneously the effect of one cause, I consider them all, so
far, as one particular thing.
