      §22. Follow a Child from its Birth, and observe the alterations
that time makes, and you shall find, as the Mind by the Senses
comes more and more to be furnished with Ideas, it comes to be more
and more awake; thinks more, the more it has matter to think on.
After some time, it begins to know the Objects, which being most
familiar with it, have made lasting Impressions. Thus it comes,
by degrees, to know the Persons it daily converses with, and dis-
tinguish them from Strangers; which are Instances and Effects of
its coming to retain and distinguish the Ideas the Senses convey to
it: And so we may observe, how the Mind, by degrees, improves in
these, and advances to the Exercise of those other Faculties of En-
larging, Compounding, and Abstracting its Ideas, and of reasoning
about them, and reflecting upon all these, of which, I shall have
occasion to speak more hereafter.
Locke Hum II, 1, §22, p. 117
