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, between the problem of contraries. (Are these 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 aesthetic activity in particular, and one of the most obscure and disputed concepts of Aesthetic which arises at this point: the concept of the _Beautiful_. [Sidenote] _The Beautiful as the value of expression, or expression and nothing more._ Aesthetic, intellectual, economic, and ethical values and disvalues are variously denominated in current speech: _beautiful, true, good, useful, just_, and so on--these words designate the free development of spiritual activity, action, scientific research, artistic production, when they are successful; _ugly, false, bad, useless, unbecoming, unjust, inexact_ designate embarrassed activity, the product of which is a failure. In linguistic usage, these denominations are being continually shifted from one order of facts to another, and from this to that. _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_. Many philosophers, especially aestheticians, have lost their heads in their pursuit of these most varied uses: they have entered an inextricable and impervious verbal labyrinth. For this reason it has hitherto seemed convenient studiously to avoid the use of the word beautiful to indicate successful expression. But after all the explanations that have been given, and all danger of misunderstanding being now dissipated, and since, on the other hand, we cannot fail to recognize that the prevailing tendency, alike in current speech and in philosophy, is to limit the meaning of the vocable _beautiful_ altogether to the aesthetic value, we may define beauty as _successful expression_, or better, as _expression_ and nothing more, because expression, when it is not successful, is not expression.
