We will content ourselves with this definition of the two terms, without entering into the problem of the relation between value and disvalue, that is, the problem of contraries (that is to say, whether they are to be thought of dualistically, as two beings or two orders of beings, like Ormuzd and Ahriman, angels and devils, enemies to one another; or as a unity, which is also contrariety). This definition of the two terms will be sufficient for our purpose, which is to make clear the nature of æsthetic activity, and at this particular point one of the most obscure and disputed concepts of Æsthetic: the concept of the _Beautiful._ [Sidenote: _The Beautiful as the value of expression, or expression without qualification._] Æsthetic, intellectual, economic and ethical values and disvalues are variously denominated in current speech: _beautiful, true, good, useful, expedient, just, right_ and so on--thus designating the free development of spiritual activity, action, scientific research, artistic production, when they are successful; _ugly, false, bad, useless, inexpedient, unjust,_ wrong designating embarrassed activity, the product that is a failure. In linguistic usage, these denominations are being continually shifted from one order of facts to another. _Beautiful,_ for instance, is said not only of a successful expression, but also of a scientific truth, of an action successfully achieved, and of a moral action: thus we talk of an _intellectual beauty,_ of a _beautiful action,_ of a _moral beauty._ The attempt to keep up with these infinitely varying usages leads into a trackless labyrinth of verbalism in which many philosophers and students of art have lost their way. For this reason we have thought it best studiously to avoid the use of the word "beautiful" to indicate successful expression in its positive value. But after all the explanations that we have given, all danger of misunderstanding being now dissipated, and since on the other hand we cannot fail to recognize that the prevailing tendency, both in current speech and in philosophy, is to limit the meaning of the word "beautiful" precisely to the æsthetic value, it seems now both permissible and advisable to define beauty as _successful expression,_ or rather, as _expression_ and nothing more, because expression when it is not successful is not expression.
