All that can be admitted is that sometimes we possess thoughts (concepts) in an intuitive form, or in an abbreviated or, better, peculiar expression, sufficient for us, but not sufficient to communicate it with ease to another or other definite individuals. Hence people say inaccurately, that we have the thought without the expression; whereas it should properly be said that we have, indeed, the expression, but in a form that is not easy of social communication. This, however, is a very variable and altogether relative fact. There are always people who catch our thought on the wing, and prefer it in this abbreviated form, and would be displeased with the greater development of it, necessary for other people. In other words, the thought considered abstractly and logically will be the same; but aesthetically we are dealing with two different intuition-expressions, into both of which enter different psychological elements. The same argument suffices to destroy, that is, to interpret correctly, the altogether empirical distinction between an _internal_ and an _external_ language. [Sidenote] _Art and science._ The most lofty manifestations, the summits of intellectual and of intuitive knowledge shining from afar, are called, as we know, Art and Science. Art and Science, then, are different and yet linked together; they meet on one side, which is the aesthetic side. Every scientific work is also a work of art. The aesthetic side may remain little noticed, when our mind is altogether taken up with the effort to understand the thought of the man of science, and to examine its truth. But it is no longer concealed, when we pass from the activity of understanding to that of contemplation, and behold that thought either developed before us, limpid, exact, well-shaped, without superfluous words, without lack of words, with appropriate rhythm and intonation; or confused, broken, embarrassed, tentative. Great thinkers are sometimes termed great writers, while other equally great thinkers remain more or less fragmentary writers, if indeed their fragments are scientifically to be compared with harmonious, coherent, and perfect works.
