Made voluntarily.       §2. 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 it self: but when it has once got these simple Ideas, it is not
confined barely to Observation, and what offers it self 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.
