(1) The _Idealism_ of purposiveness (I always understand here by
this, objective purposiveness) is either that of the _casuality_ or
the _fatality_ of the determination of nature in the purposive form
of its products. The former principle treats of the reference of
matter to the physical basis of its form, viz. the laws of motion;
the second, its reference to the _hyperphysical_ basis of itself and
of the whole of nature. The system of _casuality_ that is ascribed to
_Epicurus_ or _Democritus_ is, taken literally, so plainly absurd
that it need not detain us. Opposed to this is the system of fatality,
of which _Spinoza_ is taken as the author, although it is much
older according to all appearance. This, as it appeals to something
supersensible to which our insight does not extend, is not so easy to
controvert; but that is because its concept of the original Being is
not possible to understand. But so much is clear, that on this theory
the purposive combination in the world must be taken as undesigned;
for although derived from an original Being, it is not derived from
its Understanding or from any design on its part, but rather from
the necessity of its nature and of the world-unity which emanates
therefrom. Consequently the Fatalism of purposiveness is at the same
time an Idealism.
(2) The _Realism_ of the purposiveness of nature is also either
physical or hyperphysical. The _former_ bases the purposes in nature,
by the analogy of a faculty acting with design, on the _life of matter_
(either its own or the life of an inner principle in it, a world-soul)
and is called _Hylozoism_. The _latter_ derives them from the original
ground of the universe, as from an intelligent Being (originally
living), who produces them with design, and is _Theism_.[112]
§ 73. _None of the above systems give what they pretend_
What do all these systems desire? They desire to explain our
teleological judgements about nature, and they go so to work therewith
that some deny their truth and, consequently, explain them as an
Idealism of Nature (represented as Art); others recognise them as true,
and promise to establish the possibility of a nature in accordance with
the Idea of final causes.
