Lesson 45-1 Of men and galaxies
In man's earlydays, competition with other creatures must have been critical. But this phaseof our development is now finished. Indeed, we lack practice and experiencenowadays in dealing with primitive conditions. I am sure that, without modernweapons, I would make a very poor show of disputing the ownership of a cavewith a bear, and in this I do not think that I stand alone. The last creatureto compete with man was the mosquito. But even the mosquito has been subdued byattention to drainage and by chemical sprays.
Competitionbetween ourselves, person against person, community against community, stillpersists, however; and it is as fierce as it ever was.
But thecompetition of man against man is not the simple process envisioned in biology.
