In man's early days, competition with other creatures must have been critical.But this phase of our development is now finished. Indeed, we lack practice and experience nowadays in dealing with primitive conditions. (1)_______________________. The last creature to compete with man was the mosquito. But even the mosquito has been subdued by attention to drainage and by chemical sprays. Competition between ourselves, person against person, community against community, still persists, however; and it is as fierce as it ever was. But the competition of man against man is not the simple process envisioned in biology. (2)_______________________. Our environment is chiefly conditioned by the things we believe. Morocco and California are bits of the Earth in very similar latitudes, both on the west coasts of continents with similar climates, and probably with rather similar natural resources. Yet their present development is wholly different, not so much because of different people even, but because of the different thoughts that exist in the minds of their inhabitants. This is the point I wish to emphasize. The most important factor in our environment is the state of our own minds.(3)_______________________.
