That is not likely ever to happen, for reasons which it would take very much too long to speak of now.

But there is evidence that the most selfish of all human passions will eventually be brought under control--under such control that the present cause of wellnigh all human suffering, the pressure of population, will be practically removed.

And there is psychological evidence that the human mind will undergo such changes that wrong-doing, in the sense of unkindly action, will become almost impossible, and that the highest pleasure will be found not in selfishness but in unselfishness.

Of course there are thousands of things to think about, suggested by this discovery of the life of ants.

I am only telling the more important ones.
