14. Ideas of modes and relations are archetypes and cannot be adequate.
Thirdly, complex ideas of modes and
relations are originals, and archetypes; are not copies, nor made after the pattern of any real existence, to which
the mind intends them to be conformable, and exactly to answer. These being such collections of simple ideas that
the mind itself puts together, and such collections that each of them contains in it precisely all that the mind
intends that it should, they are archetypes and essences of modes that may exist; and so are designed only for, and
belong only to such modes as, when they do exist, have an exact conformity with those complex ideas. The ideas,
therefore, of modes and relations cannot but be adequate.
