presume to explain the possibility of things, but he is satisfied with giving a solid basis to the knowledge that makes us understand the possibility of experience. And as experience would be equally impossible without this autonomy in the mind, and without the absolute unity of the mind, it lays down these two conceptions as two conditions of experience equally necessary without troubling itself any more to reconcile them. Moreover, this immanence of two fundamental impulses does not in any degree contradict the absolute unity of the mind, as soon as the mind itself,- its selfhood-is distinguished from these two motors. No doubt, these two impulses exist and act in it, but itself is neither matter nor form, nor the sensuous nor reason, and this is a point that does not seem always to have occurred to those who only look upon the mind as itself acting when its acts are in harmony with reason, and who declare it passive when its acts contradict reason.
Arrived at its development, each of these two fundamental impulsions tends of necessity and by its nature to satisfy itself; but precisely because each of them has a necessary tendency, and both nevertheless have an opposite tendency, this twofold constraint mutually destroys itself, and the will preserves an entire freedom between them both. It is therefore the will that conducts itself like a power-as the basis of reality-with respect to both these impulses; but neither of them can by itself act as a power with respect to the other. A violent man, by his positive tendency to justice, which never fails in him, is turned away from injustice; nor can a temptation of pleasure, however strong, make a strong character violate its principles. There is in man no other power than his will; and death alone, which destroys man, or some privation of self-consciousness, is the only thing that can rob man of his internal freedom.
An external necessity determines our condition, our existence in time, by means of the sensuous. The latter is quite involuntary, and directly it is produced in us, we are necessarily passive. In the same manner an internal necessity awakens our personality in connection with sensations, and by its antagonism with them; for consciousness cannot depend on the will, which presupposes it. This primitive manifestation of personality is no more a merit to us than its privation is a defect in us. Reason can only be required in a being who is self-conscious, for reason is an absolute consecutiveness and universality of consciousness; before this is the case, he is not a man, nor can any act of humanity be expected from him. The metaphysician can no more explain the limitation imposed by sensation on a free and autonomous mind than the natural philosopher can understand the infinite, which is revealed in consciousness in connection with these limits. Neither abstraction nor experience can bring us back to the source whence issue our ideas of necessity and of universality; this source is concealed in its origin in time from the observer, and its super-sensuous origin from the researches of the metaphysician. But, to sum up in a few words, consciousness is there, and, together, with its immutable unity, the law of all that is for man is established, as well as of all that is to be by man, for his understanding and his activity. The ideas of truth and of right present themselves inevitable, incorruptible, immeasurable, even in the age of sensuousness; and without our being able to say why or how, we see eternity in time, the necessary following the contingent. It is thus that, without any share on the part of the subject, the sensation and self-consciousness arise, and the origin of both is beyond our volition, as it is out of the sphere of our knowledge.
But as soon as these two faculties have passed into action, and man has verified by experience, through the medium of sensation, a determinate existence, and through the medium of consciousness, its absolute existence, the two fundamental impulses exert their influence directly their object is given. The sensuous impulse is awakened with the experience of life-with the beginning of the individual; the rational impulsion with the experience of law- with the beginning of his personality; and it is only when these two inclinations have come into existence that the human type is realised. Up to that time, everything takes place in man according to the law of necessity; but now the hand of nature lets him go, and it is for him to keep upright humanity which nature places as a germ in his heart. And thus we see that directly the two opposite and fundamental impulses exercise their influence in him, both lose their constraint, and the autonomy of two necessities gives birth to freedom.
Letter XX.
That freedom is an active and not a passive principle results from its very conception; but that liberty itself should be an effect of nature (taking this word in its widest sense), and not the work of man, and therefore that it can be favoured or thwarted by natural means, is the necessary consequence of that which precedes. It begins only when man is complete, and when these two fundamental impulsions have been developed. It will then be wanting whilst he is incomplete, and while one of these impulsions is excluded, and it will be re-established by all that gives back to man his integrity.
Thus it is possible, both with regard to the entire species as to the individual, to remark the moment when man is yet incomplete, and when one of the two exclusions acts solely in him. We know that man commences by life simply, to end by form; that he is more of an individual than a person, and that he starts from the limited or finite to approach the infinite. The sensuous impulsion comes into play therefore before the rational impulsion, because sensation precedes consciousness; and in this priority of sensuous impulsion we find the key of the history of the whole of human liberty.
There is a moment, in fact, when the instinct of life, not yet opposed to the instinct of form, acts as nature and as necessity; when the sensuous is a power because man has not begun; for even in man there can be no other power than his will. But when man shall have attained to the power of thought, reason, on the contrary, will be a power, and moral or logical necessity will take the place of physical necessity. Sensuous power must then be annihilated before the law which must govern it can be established. It is not enough that something shall begin which as yet was not; previously something must end which had begun. Man cannot pass immediately from sensuousness to thought. He must step backwards, for it is only when one determination is suppressed that the contrary determination can take place. Consequently, in order to exchange passive against active liberty, a passive determination against an active, he must be momentarily free from all determination, and must traverse a state of pure determinability. He has then to return in some degree to that state of pure negative indetermination in which he was before his senses were affected by anything. But this state was absolutely empty of all contents, and now the question is to reconcile an equal determination and a determinability equally without limit, with the greatest possible fullness, because from this situation something positive must immediately follow. The determination which man received by sensation must be preserved, because he should not lose the reality; but at the same time, in so far as finite, it should be suppressed, because a determinability without limit would take place. The problem consists then in annihilating the determination of the mode of existence, and yet at the same time in preserving it, which is only possible in one way: in opposing to it another. The two sides of a balance are in equilibrium when empty; they are also in equilibrium when their contents are of equal weight.
Thus, to pass from sensation to thought, the soul traverses a medium position, in which sensibility and reason are at the same time active, and thus they mutually destroy their determinant power, and by their antagonism produce a negation. This medium situation in which the soul is neither physically nor morally constrained, and yet is in both ways active, merits essentially the name of a free situation; and if we call the state of sensuous determination physical, and the state of rational determination logical or moral, that state of real and active determination should be called the aesthetic.
Letter XXI.
I have remarked in the beginning of the foregoing letter that there is a twofold condition of determinableness and a twofold condition of determination. And now I can clear up this proposition.
The mind can be determined-is determinable-only in as far as it is not determined; it is, however, determinable also, in as far as it is not exclusively determined; that is, if it is not confined in its determination. The former is only a want of determination- it is without limits, because it is without reality; but the latter, the aesthetic determinableness, has no limits, because it unites all reality.
The mind is determined, inasmuch as it is only limited; but it is also determined because it limits itself of its own absolute capacity. It is situated in the former position when it feels, in the second when it thinks. Accordingly the aesthetic constitution is in relation to determinableness what thought is in relation to determination. The latter is a negative from internal infinite completeness, the former a limitation from internal infinite power. Feeling and thought come into contact in one single point, the mind is determined in both conditions, the man becomes something and exists-either as individual or person-by exclusion; in other cases these two faculties stand infinitely apart. Just in the same manner, the aesthetic determinableness comes in contact with the mere want of
