Nevertheless, amid all the false conventions, the sham glories and cowardices of our civilization, there abides in the heart the craving for true love, and the idea of it leaps continually into flame in the young. In spite of the ridicule of the elders, in spite of blunders and tragic failures, in spite of dishonesties and deceptions--nevertheless, it continues to happen that out of a thousand maidens the youth finds one whose presence thrills him with a new and terrible emotion, whose lightest touch makes him shiver, almost makes his knees give way. If you will recall what I have written about instinct and reason, you will know that I am not a blind worshipper of our ancient mother nature. I am not humble in my attitude toward her, but perfectly willing to say when I know more than she does. On the other hand, when I know nothing or next to nothing, I am shy of contradicting my ancient mother, and disposed to give respectful heed to her promptings. One of the things about which we know almost nothing at present is the subject of eugenics. We are only at the beginning of trying to find out what matings produce the best offspring. Meantime, we ought to consider those indications which nature gives us, just as we consider her advice about what food to eat and what rest to take. It is not my idea that science will ever take men and women and marry them in cold blood, as today we breed our cattle. What I think will happen is that young men and women will meet one another, as they do at present, and will find the love impulse awakening; they will then submit their love to investigation, as to whether they should follow that impulse, or should wait. In other words, I do not believe that science will ever do away with the raptures of love, but will make itself the servant of these raptures, finding out what they mean, and how their precious essence may be preserved.
