1.
Of the Tree of Knowledge.—Probability, but no truth; the semblance of freedom, but no freedom—these are the two fruits by virtue of which the tree of knowledge cannot be confounded with the tree of life.
2.
The World's Reason.—That the world is not the abstract essence of an eternal reasonableness is sufficiently proved by the fact that that bit of the world which we know—I mean our human reason—is none too reasonable. And if this is not eternally and wholly wise and reasonable, the rest of the world will not be so either. Here the conclusion a minori ad majus, a parte ad totum holds good, and that with decisive force.
3.
“In the Beginning was.”—To glorify the origin—that is the metaphysical after-shoot which sprouts again at the contemplation of history, and absolutely makes us imagine that in the beginning of things lies all that is most valuable and essential.
4.
Standard for the Value of Truth.—The difficulty of climbing mountains is no gauge of their height. Yet in the case of science it is different!—we are told by certain persons who wish to be considered “the initiated,”—the difficulty in finding [pg 185] truth is to determine the value of truth! This insane morality originates in the idea that “truths” are really nothing more than gymnastic appliances, with which we have to exercise ourselves until we are thoroughly tired. It is a morality for the athletes and gymnasts of the intellect.
5.
Use of Words and Reality.—There exists a simulated contempt for all the things that mankind actually holds most important, for all everyday matters. For instance, we say “we only eat to live”—an abominable lie, like that which speaks of the procreation of children as the real purpose of all sexual pleasure. Conversely, the reverence for “the most important things” is hardly ever quite genuine. The priests and metaphysicians have indeed accustomed us to a hypocritically exaggerated use of words regarding these matters, but they have not altered the feeling that these most important things are not so important as those despised “everyday matters.” A fatal consequence of this twofold hypocrisy is that we never make these everyday matters (such as eating, housing, clothes, and intercourse) the object of a constant unprejudiced and universal reflection and revision, but, as such a process appears degrading, we divert from them our serious intellectual and artistic side. Hence in such matters habit and frivolity win an easy victory over the thoughtless, especially over inexperienced youth. On the other hand, our continual transgressions of the simplest laws of body and mind reduce us all, young [pg 186] and old, to a disgraceful state of dependence and servitude—I mean to that fundamentally superfluous dependence upon physicians, teachers and clergymen, whose dead-weight still lies heavy upon the whole of society.

Earthly Infirmities and their Main Cause.—If we look about us, we are always coming across men who have eaten eggs all their lives without observing that the oblong-shaped taste the best; who do not know that a thunder-storm is beneficial to the stomach; that perfumes are most fragrant in cold, clear air; that our sense of taste varies in different parts of our mouths; that every meal at which we talk well or listen well does harm to the digestion. If we are not satisfied with these examples of defective powers of observation, we shall concede all the more readily that the everyday matters are very imperfectly seen and rarely observed by the majority. Is this a matter of indifference?—Let us remember, after all, that from this defect are derived nearly all the bodily and spiritual infirmities of the individual. Ignorance of what is good and bad for us, in the arrangement of our mode of life, the division of our day, the selection of our friends and the time we devote to them, in business and leisure, commanding and obeying, our feeling for nature and for art, our eating, sleeping, and meditation; ignorance and lack of keen perceptions in the smallest and most ordinary details—this it is that makes the world “a vale of tears” for so many. Let us not say that here [pg 187] as everywhere the fault lies with human unreason. Of reason there is enough and to spare, but it is wrongly directed and artificially diverted from these little intimate things. Priests and teachers, and the sublime ambition of all idealists, coarser and subtler, din it even into the child's ears that the means of serving mankind at large depend upon altogether different things—upon the salvation of the soul, the service of the State, the advancement of science, or even upon social position and property; whereas the needs of the individual, his requirements great and small during the twenty-four hours of the day, are quite paltry or indifferent.—Even Socrates attacked with all his might this arrogant neglect of the human for the benefit of humanity, and loved to indicate by a quotation from Homer the true sphere and conception of all anxiety and reflection: “All that really matters,” he said, “is the good and evil hap I find at home.”
