I could tell him about the mechanism of sex—just as forel and a dozen writers have done.
First of all, forel proves that the war-making instinct is not fundamental.
But forel discerns here and there sparks of reflective consciousness, germs of individual will.
In such circumstances, says forel, they will never resume the struggle.
forel has in this connection compared the use of contraceptives to the use of eye-glasses.
Among ants alone, so forel informs me, there are more than 7,500 species.
As forel says: "The greatest enemies of ants are other ants, just as the greatest enemies of men are other men."
It's very few of them, Yetta, who have read a book like forel's.
According to Prof. forel there are both longitudinal and transverse seiches.
Some sexologists like Kisch and Vaerting believe it does play an important rôle; others, like forel, believe it plays none.
