In the reception of simple Ideas, the Undertanding is for the most part passive.       §25. In this Part, the Understanding is meerly passive; and whether
or no, it will have these Beginnings, and as it were materials of
Knowledge, is not in its own Power. For the Objects of our Senses,
do, many of them, obtrude their particular Ideas upon our minds,
whether we will or no: And the Operations of our minds, will not
let us be without, at least some obscure Notions of them. No Man,
can be wholly ignorant of what he does, when he thinks. These
simple Ideas, when offered to the mind, the Understanding can no more
refuse to have, nor alter, when they are imprinted, nor blot them
out, and make new ones in it self, than a mirror can refuse, alter, or
obliterate the Images or Ideas, which, the Objects set before it, do
therein produce. As the Bodies that surround us, do diversly affect
our Organs, the mind is forced to receive the Impressions; and
cannot avoid the Perception of those Ideas that are annexed to them.
