There are, first of all, two kinds of authors: those who write for the subject’s sake, and those who write for writing’s sake. While the one have had thoughts or experiences which seem to them worth communicating, the others want money; and so they write, for money. Their thinking is part of the business of writing. They may be recognized by the way in which they spin out their thoughts to the greatest possible length; then, too, by the very nature of their thoughts, which are only half-true, perverse, forced, vacillating; again, by the aversion they generally show to saying anything straight out, so that they may seem other than they are. Hence their writing is deficient in clearness and definiteness, and it is not long before they betray that their only object in writing at all is to cover paper. This sometimes happens with the best authors; now and then, for example, with Lessing in his Dramaturgie, and even in many of Jean Paul’s romances. As soon as the reader perceives this, let him throw the book away; for time is precious. The truth is that when an author begins to write for the sake of covering paper, he is cheating the reader; because he writes under the pretext that he has something to say.

The author has dwelt, especially in the theoretical part, upon general questions which are side-issues in respect to the theme that he has treated. But this will not seem a digression to those who remember that, strictly speaking, there are no particular philosophical sciences, standing by themselves. Philosophy is unity, and when we treat of Æsthetic or of Logic or of Ethics, we treat always of the whole of philosophy, although illustrating for didactic purposes only one side of that inseparable unity. In like manner, owing to this intimate connexion of all the parts of philosophy, the uncertainty and misunderstanding as to the æsthetic activity, the representative and productive imagination, this firstborn of the spiritual activities, mainstay of the others, generates everywhere else misunderstandings, uncertainties and errors: in Psychology as in Logic, in History as in the Philosophy of Practice. If language is the first spiritual manifestation, and if the æsthetic form is language itself, taken in all its true scientific extension, it is hopeless to try to understand clearly the later and more complicated phases of the life of the spirit, when their first and simplest moment is ill known, mutilated and disfigured. From the explanation of the æsthetic activity is also to be expected the correction of several concepts and the solution of certain philosophic problems which generally seem to be almost desperate. Such is precisely the spirit animating the present work. And if the present attempt and the historical illustrations which accompany it may be of use in winning friends to these studies, by levelling obstacles and indicating paths to be followed; if this happen, especially here in Italy, whose æsthetic traditions (as has been demonstrated in its place) are very noble, the author will consider that he has gained his end, and one of his keenest desires will have been satisfied.
