2. Made voluntarily.
In this faculty of repeating and joining together its ideas, the mind has great power in varying
and multiplying the objects of its thoughts, infinitely beyond what sensation or reflection furnished it with: but all
this still confined to those simple ideas which it received from those two sources, and which are the ultimate
materials of all its compositions. For simple ideas are all from things themselves, and of these the mind can have
no more, nor other than what are suggested to it. It can have no other ideas of sensible qualities than what come
from without by the senses; nor any ideas of other kind of operations of a thinking substance, than what it finds in
itself But when it has once got these simple ideas, it is not confined barely to observation, and what offers itself
from without; it can, by its own power, put together those ideas it has, and make new complex ones, which it
never received so united.
