Brutes compound but little.       §7. In this also, I suppose, Brutes come far short of Men. For
though they take in, and retain together several Combinations of
simple Ideas, as possibly the Shape, Smell, and Voice of his Master,
make up the complex Idea a Dog has of him; or rather are so many
distinct Marks whereby he knows him: yet, I do not think they do
of themselves ever compound them, and make complex Ideas. And
perhaps even where we think they have complex Ideas,’tis only one
simple one that directs them in the knowledge of several things,
which possibly they distinguish less by their Sight, than we
imagine. For I have been credibly informed, that a Bitch will nurse,
play with, and be fond of young Foxes, as much as, and in place of
her Puppies, if you can but get them once to suck her so long, that
her Milk may go through them. And those animals, which have a
numerous brood of young ones at once, appear not to have any
knowledge of their number; for though they are mightily concerned
for any of their Young, that are taken from them whilst they are in
sight or hearing, yet if one or two of them be stollen from them in
their absence, or without noise, they appear not to miss them; or to
have any sense, that their number is lessen’d.
