The cause of such references.       §6. These Suppositions, the Mind is very apt tacitly to make
concerning its own Ideas. But yet if we will examine it, we shall find
it is chiefly, if not only concerning its abstract complex Ideas. For
the natural tendency of the Mind being towards Knowledge; and
finding that, if it should proceed by, and dwell upon only particular
Things, its Progress would be very slow, and its Work endless:
Therefore to shorten its way to Knowledge, and make each

Perception the more comprehensive; the first Thing it does, as
the Foundation of the easier enlarging its Knowledge, either by
Contemplation of the things themselves, that it would know; or
conference with others about them, is to bind them into Bundles,
and rank them so into sorts, that what Knowledge it gets of any of
them, it may thereby with assurance extend to all of that sort; and
so advance by larger steps in that, which is its great Business,
Knowledge. This, as I have elsewhere shewed, is the Reason, why
we collect Things under comprehensive Ideas, with Names annexed
to them into Genera and Species; i.e. into kinds, and sorts.
