rting in the least degree his physical
aim. The exigencies of nature with regard to him turn only upon what he
does--upon the substance of his acts; but the ends of nature in no degree
determine the way in which he acts, the form of his actions. On the
contrary, the exigencies of reason have rigorously the form of his
activity for its object. Thus, so much as it is necessary for the moral
destination of man, that he be purely moral, that he shows an absolute
personal activity, so much is he indifferent that his physical
destination be entirely physical, that he acts in a manner entirely
passive. Henceforth with regard to this last destination, it entirely
depends on him to fulfil it solely as a sensuous being and natural force
(as a force which acts only as it diminishes) or, at the same time, as
absolute force, as a rational being. To which of these does his dignity
best respond? Of this there can be no question. It is as disgraceful
and contemptible for him to do under sensuous impulsion that which he
ought to have determined merely by the motive of duty, as it is noble and
honorable for him to incline towards conformity with laws, harmony,
independence; there even where the vulgar man only satisfies a legitimate
want. In a word, in the domain of truth and morality, sensuousness must
have nothing to determine; but in the sphere of happiness, form may find
a place, and the instinct of play prevail.

Thus then, in the indifferent sphere of physical life, man ought to
already commence his moral life; his own proper activity ought already to
make way in passivity, and his rational liberty beyond the limits of
sense; he ought already to impose the law of his will upon his
inclinations; he ought--if you will permit me the expression--to carry
into the domain of matter the war against matter, in order to be
dispensed from combating this redoubtable enemy upon the sacred field of
liberty; he ought to learn to have nobler desires, not to be forced to
have sublime volitions. This is the fruit of aesthetic culture, which
submits to the laws of the beautiful, in which neither the laws of nature
nor those of reason suffer, which does not force the will of man, and
which by the form it gives to exterior life already opens internal life.

Accordingly three different moments or stages of development can be
distinguished, which the individual man, as well as the whole race, must
of necessity traverse in a deter
