The same will be the case in the investigation that we have begun of the practical form of the spirit and of the problems to which it gives rise. This concept of feeling has been mingled with them all, and propositions have been formed, of which we shall indicate the true significance in the proper places. Beginning at once and limiting ourselves solely to the question of the existence of a peculiar practical form, it is easy to understand why it has so often been maintained against the intellectual and theoretical exclusivists, that the will consists, not of knowledge, but of feeling; that the principle of action, far from being an intellectual principle, is sentimental emotion; that in order to produce a volition, reason, ideas, and facts perceived do not suffice, but that it is necessary that all these things be transformed into feelings, which must take possession of the soul; that the base of life lived, that is, of practical life, is not thought, but feeling, and so on. With these formulæ was recognized the peculiarity of the practical activity. The theory of feeling in respect of the practical represents progress as compared with the intellectualistic theory, because the appearance of indeterminateness is progress as compared with bad determinateness, and contains in itself the new and more complete determinateness.
Negation of feeling.
But in this very way of ours of understanding the value of these formulæ, is implied their resolute negation, when they tend to persist, after having accomplished their function, and to maintain side by side with the theory of the practical a third general form of the spirit, namely feeling. No spiritual fact or manifestation of activity can be adduced, which, examined without superficiality, is not reducible to an act of fancy, intellect and perception, that is, of theory (when it is not at once revealed as an abstraction or as a merely psychological class of these acts); or to an act of utilitarian or ethical volition (when it is not here too a psychological class, variously designated as aspirations, passions, affections, and the like). Let him who will search his spirit and attempt to indicate one single act, differing from the above, as something new and original and deserving of the special denomination of feeling.
Its deductive exclusion.
This constatation of fact (we repeat the warning) is but the first step in the complete philosophical demonstration, which demands that we show not only that a third form does not exist, but that it cannot exist. This demonstration will be given further on, and will coincide with that of the demonstration of the necessity of the two forms, theoretical and practical; a duality that is unity and a unity that is duality. Recognizing the legitimacy of the demand for a philosophical deduction of the forms of the spirit, and therefore of a deductive exclusion of those that are spurious and wrongly adopted, it seems that if it be somewhat delayed, such a mode of exclusion will also yield clearer results.
