Error of those who maintain the exclusive precedence of either.

The indubitability of this affirmation, which no force of sophistry can destroy, renders fallacious both the opposite theses, which have several times been variously proposed and maintained: the exclusive priority of the theoretic, and the exclusive priority of the practical.

Those who maintain them enter into so desperate a contest with reality, that in order to issue from it without too much dishonour, they are finally compelled to call in the aid of a third term, which is in turn either thought that is not thought, or will that is not will, or something grey that contains in itself thought and will, without being either the one or the other, nor the unity of that duality. On the one hand is postulated a Logos, a thought in se (one does not understand how this can ever think and be thought), and it is made to adopt the resolution (which one does not understand how it can ever adopt) of coming forth from itself and creating a nature, in order to be able to return finally to itself, by means of this alienation, and to be henceforth per se, that is to say, able to think and to will. The defect of this artificial construction, its mythological and religious origin, can be said to have been already revealed, in the comparison employed with reference to it by the author who maintained it (Hegel), to the effect that the Logos is God before the creation of the world: a God, that is to say, altogether unreal and absurd. On the other hand, the excogitation of a blind Will (Schelling, Schopenhauer) completely tallies with this Thought that does not think because it has not previously willed, and that does not truly will because it has not previously thought, and all of a sudden fashions for itself the instrument of knowledge, to succeed in surpassing itself in this alienation from itself, by means of liberation from willing obtained in the contemplation of the ideas and in asceticism. Here, too, we must repeat that the one error passes over and converts itself into the other, and this inevitable conversion causes the other secondary and hybrid forms of theory to have but slight interest, those in which the priority has been conceived as that of fancy, or feeling, or the unconscious, or the indifferentiated, and the like, all of which represent vain efforts to suppress one of the two fundamental forms of the spirit, or to derive them from a third, which consciousness does not reveal.

Problem of the unity of this duality.

This however does not mean that the demand to conceive the link of that duality, or the unity of the theoretical and the practical, manifested in all these erroneous attempts, is not legitimate. But in order to conceive this, it is necessary to insist above all upon the reality of this duality, of which is sought the connection and the unity.

Not the duality of opposites.

This connection cannot be the relation or synthesis of opposites. The theoretical is not the opposite of the practical, nor the practical the opposite of the theoretical: the opposite of the theoretical is error or the false, as the opposite of the practical is the volitional contradiction or evil. The theoretical, far from being negative, is positive, not less than the practical, and inversely. Neither form can therefore be in any way debased to a simple opposite. Opposition is intrinsic to the spirit and is to be found in each one of its forms: hence the general value of the spirit (activity against passivity, rationality and reality against irrationality and unreality, being against not-being) and that of its special forms (beautiful against ugly, true against false, useful against useless, good against evil). But precisely for this reason, it cannot constitute the character of one form in respect to the other: neither that of the true against the good, nor that of the beautiful against the useful, and so on.

Not duality of finite and infinite.

Nor can the connection be thought as are thought the subdivisions of the theoretic and the practical forms, or according to the relations of individual to universal, of finite to infinite, the first of which terms conditions the second, but is conditioned by it only in an implicit manner. Of the two theoretical forms (and we shall see further on that the forms of the practical are also two), the æsthetic precedes the logical and is autonomous: a song, a story, a statue, do not express any concept; but the philosophy that gives the concept, is at the same time fancy, expression, word: the prose of the philosopher is his song. The æsthetic form is the knowledge of the individual; the logical that of the universal, which is also individual. But this relation that arises within the theoretic, as within the practical form, cannot be transported to the relation of the two forms without logical incoherence: the subdivision, so to speak, is not the division. Thought is not the finite in respect of willing, which is the infinite; nor is the will the finite in respect of thought, which is the infinite. Thought and will are both of them at once finite and infinite, individual and universal. He who passes from action to thought, does not limit his own being by becoming finite; nor does he limit it by passing from thought to action; or better, in both cases he makes himself finite to attain to the infinite; poet to open to himself the way to the thought of the eternally true; man of action, that he may dedicate his work to the eternal good.
