That which constitutes the painful delight of tragedy is cruelty; that which operates agreeably in so-called tragic sympathy, and at the basis even of everything sublime, up to the highest and most delicate thrills of metaphysics, obtains its sweetness solely from the intermingled ingredient of cruelty.

What the Roman enjoys in the arena, the Christian in the ecstasies of the cross, the Spaniard at the sight of the faggot and stake, or of the bull-fight, the present-day Japanese who presses his way to the tragedy, the workman of the Parisian suburbs who has a homesickness for bloody revolutions, the Wagnerienne who, with unhinged will, "undergoes" the performance of "Tristan and Isolde"-- what all these enjoy, and strive with mysterious ardour to drink in, is the philtre of the great Circe "cruelty." Here, to be sure, we must put aside entirely the blundering psychology of former times, which could only teach with regard to cruelty that it originated at the sight of the suffering of OTHERS: there is an abundant, super-abundant enjoyment even in one's own suffering, in causing one's own suffering--and wherever man has allowed himself to be persuaded to self-denial in the RELIGIOUS sense, or to self-mutilation, as among the Phoenicians and ascetics, or in general, to desensualisation, decarnalisation, and contrition, to Puritanical repentance-spasms, to vivisection of conscience and to Pascal-like SACRIFIZIA DELL' INTELLETO, he is secretly allured and impelled forwards by his cruelty, by the dangerous thrill of cruelty TOWARDS HIMSELF .-- Finally, let us consider that even the seeker of knowledge operates as an artist and glorifier of cruelty, in that he compels his spirit to perceive AGAINST its own inclination, and often enough against the wishes of his heart:--he forces it to say Nay, where he would like to affirm, love, and adore; indeed, every instance of taking a thing profoundly and fundamentally, is a violation, an intentional injuring of the fundamental will of the spirit, which instinctively aims at appearance and superficiality,--even in every desire for knowledge there is a drop of cruelty.

Perhaps what I have said here about a "fundamental will of the spirit" may not be understood without further details; I may be allowed a word of explanation .-- That imperious something which is popularly called "the spirit," wishes to be master internally and externally, and to feel itself master; it has the will of a multiplicity for a simplicity, a binding, taming, imperious, and essentially ruling will.
Its requirements and capacities here, are the same as those assigned by physiologists to everything that lives, grows, and multiplies.

The power of the spirit to appropriate foreign elements reveals itself in a strong tendency to assimilate the new to the old, to simplify the manifold, to overlook or repudiate the absolutely contradictory; just as it arbitrarily re-underlines, makes prominent, and falsifies for itself certain traits and lines in the foreign elements, in every portion of the "outside world." Its object thereby is the incorporation of new "experiences," the assortment of new things in the old arrangements--in short, growth; or more properly, the FEELING of growth, the feeling of increased power--is its object.

This same will has at its service an apparently opposed impulse of the spirit, a suddenly adopted preference of ignorance, of arbitrary shutting out, a closing of windows, an inner denial of this or that, a prohibition to approach, a sort of defensive attitude against much that is knowable, a contentment with obscurity, with the shutting-in horizon, an acceptance and approval of ignorance: as that which is all necessary according to the degree of its appropriating power, its "digestive power," to speak figuratively (and in fact "the spirit" resembles a stomach more than anything else).
