Where the logician draws the line, where the premises stop which are the result of cognition--where judgment begins, there Art begins.

But more than this even the perception of the mind is judgment again, and consequently Art; and at last, even the perception by the senses as well.

In a word, if it is impossible to imagine a human being possessing merely the faculty of cognition, devoid of judgment or the reverse, so also Art and Science can never be completely separated from each other.

The more these subtle elements of light embody themselves in the outward forms of the world, so much the more separate appear their domains; and now once more, where the object is creation and production, there is the province of Art; where the object is investigation and knowledge Science holds sway .-- After all this it results of itself that it is more fitting to say Art of War than Science of War.
So much for this, because we cannot do without these conceptions.

But now we come forward with the assertion that War is neither an Art nor a Science in the real signification, and that it is just the setting out from that starting-point of ideas which has led to a wrong direction being taken, which has caused War to be put on a par with other arts and sciences, and has led to a number of erroneous analogies.
This has indeed been felt before now, and on that it was maintained that War is a handicraft; but there was more lost than gained by that, for a handicraft is only an inferior art, and as such is also subject to definite and rigid laws.
