The intellect, as a means for the preservation of the individual, develops its chief power in dissimulation; for it is by dissimulation that the feebler, and less robust individuals preserve themselves, since it has been denied them to fight the battle of existence with horns or the sharp teeth of beasts of prey. In man this art of dissimulation reaches its acme of perfection: in him deception, flattery, falsehood and fraud, slander, display, pretentiousness, disguise, cloaking convention, and acting to others and to himself in short, the continual fluttering to and fro around the _one_ flame--Vanity: all these things are so much the rule, and the law, that few things are more incomprehensible than the way in which an honest and pure impulse to truth could have arisen among men. They are deeply immersed in illusions and dream-fancies; their eyes glance only over the surface of things and see "forms"; their sensation nowhere leads to truth, but contents itself with receiving stimuli and, so to say, with playing hide-and-seek on the back of things. In addition to that, at night man allows his dreams to lie to him a whole life-time long, without his moral sense ever trying to prevent them; whereas men are said to exist who by the exercise of a strong will have overcome the habit of snoring. What indeed _does_ man know about himself? Oh! that he could but once see himself complete, placed as it were in an illuminated glass-case! Does not nature keep secret from him most things, even about his body, _e.g.,_ the convolutions of the intestines, the quick flow of the blood-currents, the intricate vibrations of the fibres, so as to banish and lock him up in proud, delusive knowledge? Nature threw away the key; and woe co the fateful curiosity which might be able for a moment to look out and down through a crevice in the chamber of consciousness, and discover that man, indifferent to his own ignorance, is resting on the pitiless, the greedy, the insatiable, the murderous, and, as it were, hanging in dreams on the back of a tiger. Whence, in the wide world, with this state of affairs, arises the impulse to truth?
