En el Corazón de Cada Hombre Descansa una Bestia Salvaje
It is a fact, then, that in the heart of every man there lies a wild beast which only waits for an opportunity to storm and rage, in its desire to inflict pain on others, or, if they stand in his way, to kill them. It is this which is the source of all the lust of war and battle. In trying to tame and to some extent hold it in check, the intelligence, its appointed keeper, has always enough to do. People may, if they please, call it the radical evil of human nature—a name which will at least serve those with whom a word stands for an explanation. I say, however, that it is the will to live, which, more and more embittered by the constant sufferings of existence, seeks to alleviate its own torment by causing torment in others. But in this way a man gradually develops in himself real cruelty and malice. The observation may also be added that as, according to Kant, matter subsists only through the antagonism of the powers of expansion and contraction, so human society subsists only by the antagonism of hatred, or anger, and fear. For there is a moment in the life of all of us when the malignity of our nature might perhaps make us murderers, if it were not accompanied by a due admixture of fear to keep it within bounds; and this fear, again, would make a man the sport and laughing stock of every boy, if anger were not lying ready in him, and keeping watch.
