And yet there is a sure method of distinguishing true intuition, true representation, from that which is inferior to it: the spiritual fact from the mechanical, passive, natural fact. Every true intuition or representation is also _expression._ That which does not objectify itself in expression is not intuition or representation, but sensation and mere natural fact. The spirit only intuites in making, forming, expressing. He who separates intuition from expression never succeeds in reuniting them. Intuitive activity _possesses intuitions to the extent that it expresses them._ Should this proposition sound paradoxical, that is partly because, as a general rule, a too restricted meaning is given to the word "expression." It is generally restricted to what are called verbal expressions alone. But there exist also non-verbal expressions, such as those of line, colour and sound, and to all of these must be extended our affirmation, which embraces therefore every sort of manifestation of the man, as orator, musician, painter, or anything else. But be it pictorial, or verbal, or musical, or in whatever other form it appear, to no intuition can expression in one of its forms be wanting; it is, in fact, an inseparable part of intuition. How can we really possess an intuition of a geometrical figure, unless we possess so accurate an image of it as to be able to trace it immediately upon paper or on the blackboard? How can we really have an intuition of the contour of a region, for example of the island of Sicily, if we are not able to draw it as it is in all its meanderings? Every one can experience the internal illumination which follows upon his success in formulating to himself his impressions and feelings, but only so far as he is able to formulate them. Feelings or impressions, then, pass by means of words from the obscure region of the soul into the clarity of the contemplative spirit. It is impossible to distinguish intuition from expression in this cognitive process. The one appears with the other at the same instant, because they are not two, but one.
