On the other hand, that the manifestation of a _will_ is as little bound up with life and organisation as with knowledge, and that therefore the unorganised has also a will, the manifestations of which are all its fundamental qualities, which cannot be further explained,—this is an essential point in my doctrine; although the trace of such a thought is far seldomer found in writers who have preceded me than that of the will in plants, where, however, it is still unconscious. In the forming of the crystal we see, as it were, a tendency towards an attempt at life, to which, however, it does not attain, because the fluidity of which, like a living thing, it is composed at the moment of that movement is not enclosed in a _skin_, as is always the case with the latter, and consequently it has neither vessels in which that movement could go on, nor does anything separate it from the external world. Therefore, rigidity at once seizes that momentary movement, of which only the trace remains as the crystal. The thought that the will, which constitutes the basis of our own nature, is also the same will which shows itself even in the lowest unorganised phenomena, on account of which the conformity to law of both phenomena shows a perfect analogy, lies at the foundation of Goethe’s “_Wahlverwandtschaften_,” as the title indeed indicates, although he himself was unconscious of this. Mechanics and astronomy specially show us how this will conducts itself so far as it appears at the lowest grade of its manifestation merely as gravity, rigidity, and inertia. Hydraulics shows us the same thing where rigidity is wanting and the fluid material is now unrestrainedly surrendered to its predominating passion, gravity. In this sense hydraulics may be conceived as a characteristic sketch of water, for it presents to us the manifestations of will to which water is moved by gravity; these always correspond exactly to the external influences, for in the case of all non‐individual existences there is no particular character in addition to the general one; thus they can easily be referred to fixed characteristics, which are called laws, and which are learned by experience of water. These laws accurately inform us how water will conduct itself under all different circumstances, on account of its gravity, the unconditioned mobility of its parts, and its want of elasticity. Hydrostatics teaches how it is brought to rest through gravity; hydrodynamics, how it is set in motion; and the latter has also to take account of hindrances which adhesion opposes to the will of water: the two together constitute hydraulics. In the same way Chemistry teaches us how the will conducts itself when the inner qualities of materials obtain free play by being brought into a fluid state, and there appears that wonderful attraction and repulsion, separating and combining, leaving go of one to seize upon another, from which every precipitation
