[Sidenote] _Intuitive knowledge._

Human knowledge has two forms: it is either intuitive knowledge or
logical knowledge; knowledge obtained through the imagination or
knowledge obtained through the intellect; knowledge of the individual or
knowledge of the universal; of individual things or of the relations
between them: it is, in fact, productive either of images or of
concepts.

In ordinary life, constant appeal is made to intuitive knowledge. It
is said to be impossible to give expression to certain truths; that
they are not demonstrable by syllogisms; that they must be learnt
intuitively. The politician finds fault with the abstract reasoner, who
is without a lively knowledge of actual conditions; the pedagogue
insists upon the necessity of developing the intuitive faculty in the
pupil before everything else; the critic in judging a work of art makes
it a point of honour to set aside theory and abstractions, and to judge
it by direct intuition; the practical man professes to live rather by
intuition than by reason.

But this ample acknowledgment, granted to intuitive knowledge in
ordinary life, does not meet with an equal and adequate acknowledgment
in the field of theory and of philosophy. There exists a very ancient
science of intellective knowledge, admitted by all without discussion,
namely, Logic; but a science of intuitive knowledge is timidly and with
difficulty admitted by but a few. Logical knowledge has appropriated the
lion's share; and if she does not quite slay and devour her companion,
yet yields to her with difficulty the humble little place of maidservant
or doorkeeper. What, it says, is intuitive knowledge without the light
of intellective knowledge? It is a servant without a master; and though
