borrow money; or infers that people are friends from the
fact of their having common enemies.'" And then he goes on
to make these simple observations confused and perplexing by
reducing them to his logical formula.

"The derivation of the words will confirm this view.
{Eustochia} is a hitting the _mark_ successfully, a reaching
to the end, the rapid and, as it were, intuitive perception
of the truth. This is what Whewell means by saying, 'all
induction is a happy conjecture.' But when Aristotle says
that this faculty is not guided by reason ({aneu te gar
logou}), he does not mean to imply that it grows up
altogether independent of reason, any more than Whewell
means to say that all the discoveries in the inductive
sciences have been made by men taking 'shots' at them, as
boys at school do at hard passages in their Latin lessons.
On the contrary, no faculty is so absolutely the child of
reason as this faculty of happy guessing. It only attains to
perfection after the reason has been long and painfully
trained in the sphere in which the guesses are to be made.
What Aristotle does mean is, that when it has attained
perfection, we are not conscious of the share which reason
has in its operation--it is so rapid that by no analysis can
we detect the presence of reason in its action. Sir Isaac
Newton seeing the apple fall, and thence 'guessing' at the
law of gravitation, is a good instance of {eustochia}.

"{Anchinoia}, on the other hand, is a _nearness of mind_;
not a reaching to the end, but an apprehension of the best
means; not a perception of the truth, but a perception of
how the truth is to be supported. It is sometimes translated
'sagacity,' but readiness or presence of mind is better, as
sagacity rather involves the idea of consideration. In
matters purely intellectual it is ready wit. It is a sort of
shorter or more limited {eustochia}. It is more of a natural
gift than {eustochia}, because the latter is a far higher
and nobler faculty, and therefore more dependent for its
perfection on cultivation, as all our highest faculties are.
{Eustochia} is more akin to genius, {anchinoia} to practical
common sense."
