202 THE WORLD AS WILL. bk. ii.
other, which makes the maintenance of the whole of organised nature, or of the particular animal species, possible, and therefore presents itself to our judgment as the means to this end.
Inner teleology is connected with the scheme of our work in the following way. If, in accordance with what has been said, all variations of form in nature, and all multiplicity of individuals, belong not to the will itself, but merely to its objectivity and the form of this objectivity, it necessarily follows that the will is indivisible and is present as a whole in every manifestation, although the grades of its objectification, the (Platonic) Ideas, are very different from each other. We may, for the sake of simplicity, regard these different Ideas as in themselves individual and simple acts of the will, in which it expresses its nature more or less. Individuals, however, are again manifestations of the Ideas, thus of these acts, in time, space, and multiplicity. Now, in the lowest grades of objectivity, such an act (or an Idea) retains its unity in the manifestation ; while, in order to appear in higher grades, it requires a whole series of conditions and developments in time, which only collectively express its nature completely. Thus, for example the Idea that reveals itself in any general force of nature has always one single expression, although it presents itself differently according to the external relations that are present: otherwise its identity could not be proved, for this is done by abstracting the diversity that arises merely from external relations. In the same way the crystal has only one manifestation of life, crystallisation, which afterwards has its fully adequate and exhaustive expression in the rigid form, the corpse of that momentary life. The plant, however, does not express the Idea, whose phenomenon it is, at once and through a single manifestation, but in a succession of developments of its organs in time. The animal not only develops its organism in the same manner, in a succession of forms which are often very different
