Truly, in none. All those concepts are without philosophical value. They are nothing but a series of classes, which can be bent in the most various ways and multiplied at pleasure, to which it is sought to reduce the infinite complications and shadings of the values and disvalues of life. Of those classes, there are some that have an especially positive significance, like the beautiful, the sublime, the majestic, the solemn, the serious, the weighty, the noble, the elevated; others have a significance especially negative, like the ugly, the horrible, the dreadful, the tremendous, the monstrous, the foolish, the extravagant; in others prevails a mixed significance, as is the case with the comic, the tender, the melancholy, the humorous, the tragi-comic. The complications are infinite, because the individuations are infinite; hence it is not possible to construct the concepts, save in the arbitrary and approximate manner of the natural sciences, whose duty it is to make as good a plan as possible of that reality which they cannot exhaust by enumeration, nor understand and surpass speculatively. And since _Psychology_ is the naturalistic discipline, which undertakes to construct types and plans of the spiritual processes of man (of which, in fact, it is always accentuating in our day the merely empirical and descriptive character), these concepts do not appertain to Aesthetic, nor, in general, to Philosophy. They must simply be handed over to Psychology. [Sidenote] _Impossibility of rigoristic definitions of them._
