But what, then, is there left for us to hate? or are we to explain everything away? I am far from asserting that. There is still enough left in the world worth hating, and with this, war can and must be waged. Above all, there is the spirit of being bad on principle, the spirit that purposely contends against the spirit of God, and that persecutes the good because it is good and endeavors to overthrow it. To this spirit give your vigorous and outspoken hate, wherever and in whatever form it appears; but in most cases it dies out in the men who embody it, in the third or fourth generation at the very latest. Very often it changes, in their descendants, to the opposite spirit of good. To give help to evil men of this stripe, or to stand “impartially” between them and good men, instead of standing by the latter in every such conflict, is a serious fault that will be avenged on every one who is guilty of it. * * * * * A very difficult chapter to write is that on companionship with women, for they are the instruments of both the best and the worst that can be awakened in a man: on the one hand, unbridled self-gratification and alienation from all that is higher and nobler, qualities which they awaken especially in young people and which are the chief cause of the downfall of entire nations; on the other hand, a most efficacious uplift away from a man’s natural tendencies, to a wholly different, freer, and better conception of life. Most critics of women accordingly err in speaking of them as of a uniform mass similar in character, while, on the contrary, in this part of humanity there is a far more marked division into two distinct classes, and a much more constant retention and transmission of good as well as bad characteristics. In a very peculiar passage of the Old Testament the same distinction is made, even in that very early stage of humanity, between the “sons of God” and the “daughters of men,” who are not lacking in outward charm, indeed, but through their very charms become a curse. This difference in women is still to be found in our day, and so the first counsel is this: Have no unnecessary association with the “daughters of men” and guard against every closer alliance with them, no matter what may be sung by the poets, for they themselves are often led astray by just this peculiar charm of women.
