We should see the will express itself here in the lowest grade as blind striving, an obscure, inarticulate impulse, far from susceptible of being directly known. It is the simplest and the weakest mode of its objectification. But it appears as this blind and unconscious striving in the whole of unorganised nature, in all those original forces of which it is the work of physics and chemistry to discover and to study the laws, and each of which manifests itself to us in millions of phenomena which are exactly similar and regular, and show no trace of individual character, but are mere multiplicity through space and time, _i.e._, through the _principium individuationis_, as a picture is multiplied through the facets of a glass. From grade to grade objectifying itself more distinctly, yet still completely without consciousness as an obscure striving force, the will acts in the vegetable kingdom also, in which the bond of its phenomena consists no longer properly of causes, but of stimuli; and, finally, also in the vegetative part of the animal phenomenon, in the production and maturing of the animal, and in sustaining its inner economy, in which the manifestation of will is still always necessarily determined by stimuli. The ever-ascending grades of the objectification of will bring us at last to the point at which the individual that expresses the Idea could no longer receive food for its assimilation through mere movement following upon stimuli. For such a stimulus must be waited for, but the food has now come to be of a more special and definite kind, and with the ever-increasing multiplicity of the individual phenomena, the crowd and confusion has become so great that they interfere with each other, and the chance of the individual that is moved merely by stimuli and must wait for its food would be too unfavourable. From the point, therefore, at which the animal has delivered itself from the egg or the womb in which it vegetated without consciousness, its food must be sought out and selected. For this purpose movement following upon motives, and therefore consciousness, becomes necessary, and consequently it appears as an agent, μηχανη, called in at this stage of the objectification of will for the conservation of the individual and the propagation of the species. It appears represented by the brain or a large ganglion, just as every other effort or determination of the will which objectifies itself is represented by an organ, that is to say, manifests itself for the idea as an organ.(36) But with this means of assistance, this μηχανη, the _world as idea_ comes into existence at a stroke, with all its forms, object and subject, time, space, multiplicity, and causality. The world now shows its second side. Till now _mere will_, it becomes also _idea_, object of the knowing subject. The will, which up to this point followed its tendency in the dark with unerring certainty, has at this grade kindled for itself a
