The will to live, which forms the inmost core of every living being, exhibits itself most conspicuously in the higher order of animals, that is, the cleverer ones; and so in them the nature of the will may be seen and examined most clearly. For in the lower orders its activity is not so evident; it has a lower degree of objectivation; whereas, in the class which stands above the higher order of animals, that is, in men, reason enters in; and with reason comes discretion, and with discretion, the capacity of dissimulation, which throws a veil over the operations of the will. And in mankind, consequently, the will appears without its mask only in the affections and the passions. And this is the reason why passion, when it speaks, always wins credence, no matter what the passion may be; and rightly so. For the same reason the passions are the main theme of poets and the stalking horse of actors. The conspicuousness of the will in the lower order of animals explains the delight we take in dogs, apes, cats, etc.; it is the entirely naive way in which they express themselves that gives us so much pleasure.
The sight of any free animal going about its business undisturbed, seeking its food, or looking after its young, or mixing in the company of its kind, all the time being exactly what it ought to be and can be,—what a strange pleasure it gives us! Even if it is only a bird, I can watch it for a long time with delight; or a water rat or a hedgehog; or better still, a weasel, a deer, or a stag. The main reason why we take so much pleasure in looking at animals is that we like to see our own nature in such a simplified form. There is only one mendacious being in the world, and that is man. Every other is true and sincere, and makes no attempt to conceal what it is, expressing its feelings just as they are.
Many things are put down to the force of habit which are rather to be attributed to the constancy and immutability of original, innate character, according to which under like circumstances we always do the same thing: whether it happens for the first or the hundredth time, it is in virtue of the same necessity. Real force of habit, as a matter of fact, rests upon that indolent, passive disposition which seeks to relieve the intellect and the will of a fresh choice, and so makes us do what we did yesterday and have done a hundred times before, and of which we know that it will attain its object. But the truth of the matter lies deeper, and a more precise explanation of it can be given than appears at first sight. Bodies which may be moved by mechanical means only are subject to the power of inertia; and applied to bodies which may be acted on by motives, this power becomes the force of habit. The actions which we perform by mere habit come about, in fact, without any individual separate motive brought into play for the particular case: hence, in performing them, we really do not think about them. A motive was present only on the first few occasions on which the action happened, which has since become a habit: the secondary after-effect of this motive is the present habit, and it is sufficient to enable the action to continue: just as when a body had been set in motion by a push, it requires no more pushing in order to continue its motion; it will go on to all eternity, if it meets with no friction. It is the same in the case of animals: training is a habit which is forced upon them. The horse goes on drawing his cart quite contentedly, without having to be urged on: the motion is the continued effect of those strokes of the whip, which urged him on at first: by the law of inertia they have become perpetuated as habit. All this is really more than a mere parable: it is the underlying identity of the will at very different degrees of its objectivation, in virtue of which the same law of motion takes such different forms.
Vive muchos años is the ordinary greeting in Spain, and all over the earth it is quite customary to wish people a long life. It is presumably not a knowledge of life which directs such a wish; it is rather knowledge of what man is in his inmost nature, the will to live.
The wish which everyone has that he may be remembered after his death,—a wish which rises to the longing for posthumous glory in the case of those whose aims are high,—seems to me to spring from this clinging to life. When the time comes which cuts a man off from every possibility of real existence, he strives after a life which is still attainable, even though it be a shadowy and ideal one.
The deep grief we feel at the loss of a friend arises from the feeling that in every individual there is something which no words can express, something which is peculiarly his own and therefore irreparable. Omne individuum ineffabile.
