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
fulness, 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 th
