All philosophers have erred in this: they place the metaphysical, the indestructible, the eternal element in man in the _intellect_. It lies exclusively in the _will_, which is entirely different from the intellect, and alone is original. The intellect, as was most fully shown in the second book, is a secondary phenomenon, and conditioned by the brain, therefore beginning and ending with this. The will alone is that which conditions, the kernel of the whole phenomenon, consequently free from the forms of the phenomenon to which time belongs, thus also indestructible. Accordingly with death consciousness is certainly lost, but not that which produced and sustained consciousness; life is extinguished, but not the principle of life also, which manifested itself in it. Therefore a sure feeling informs every one that there is something in him which is absolutely imperishable and indestructible. Indeed the freshness and vividness of memories of the most distant time, of earliest childhood, bears witness to the fact that something in us does not pass away with time, does not grow old, but endures unchanged. But what this imperishable element is one could not make clear to oneself. It is not consciousness any more than it is the body upon which clearly consciousness depends. But it is just that which, when it appears in consciousness, presents itself as _will_. Beyond this immediate manifestation of it we certainly cannot go; because we cannot go beyond consciousness; therefore the question what that may be when it does not come within consciousness, _i.e._, what it is absolutely in itself, remains unanswerable. In the phenomenon, and by means of its forms, time and space, as _principium individuationis_, what presents itself is that the human individual perishes, while the human race, on the contrary, always remains and lives. But in the true being of things, which is free from these forms, this whole distinction between the individual and the race also disappears, and the two are immediately one. The whole will to live is in the individual, as it is in the race, and therefore the continuance of the species is merely the image of the indestructibility of the individual.
