The second biological lesson of history is that life is selection. In the competition for food or mates or power some organisms succeed and some fail… - Will Durant

Nothing should more deeply shame the modern student than the recency and inadequacy of his acquaintance with India. Here is a vast peninsula of nearly two million square miles; two-thirds as large as the United States, and twenty times the size of its master, Great Britain; 320,000,000 souls, more than in all North and South America combined, or one-fifth of the population of the earth; an impressive continuity of development and civilization from Mohenjo-daro, 2900 B.C. or earlier, to Gandhi, Raman and Tagore; faiths compassing every stage from barbarous idolatry to the most subtle and spiritual pantheism; philosophers playing a thousand variations on one monistic theme from the Upanishads eight centuries before Christ to Shankara eight centuries after him; scientists developing astronomy three thousand years ago, and winning Nobel prizes in our own time; a democratic constitution of untraceable antiquity in the villages, and wise and beneficent rulers like Ashoka and Akbar in the capitals; minstrels singing great epics almost as old as Homer, and poets holding world audiences today; artists raising gigantic temples for Hindu gods from Tibet to Ceylon and from Cambodia to Java, or carving perfect palaces by the score for Mogul kings and queens — this is the India that patient scholarship is now opening up, like a new intellectual continent, to that Western mind which only yesterday thought civilization an exclusively European thing.

So the first biological lesson of history is that life is competition. Competition is not only the life of trade, it is the trade of life — peaceful when food abounds, violent when the mouths outrun the food. Animals eat one another without qualm; civilized men consume one another by due process of law. Co-operation is real, and increases with social development, but mostly because it is a tool and form of competition; we co-operate in our group — our family, community, club, church, party, “race,” or nation — in order to strengthen our group in its competition with other groups. Competing groups have the qualities of competing individuals: acquisitiveness, pugnacity, partisanship, pride. Our states, being ourselves multiplied, are what we are; they write our natures in bolder type, and do our good and evil on an elephantine scale. We are acquisitive, greedy, and pugnacious because our blood remembers millenniums through which our forebears had to chase and fight and kill in order to survive, and had to eat to their gastric capacity for fear they should not soon capture another feast. War is a nation’s way of eating. It promotes co-operation because it is the ultimate form of competition. Until our states become members of a large and effectively protective group they will continue to act like individuals and families in the hunting stage.

Space, subjectively, is the coexistence of perceptions — perceiving two objects at once.
