Capitalism institutionalizes variety, motivates excellence, but often neglects security. Dogma, be it political or religious, promises security, claims excellence, but exorcises variety. Imperialism pursues variety and security for one group at the expense of another. But you'll find all three elements present, nonetheless. Nature, too, appears to be most concerned with security.
Boldness ventures forth only from a secure lair.
Experiments in variety are relegated to the periphery of the central, secure gene pool. Danger itself has been transformed. Mankind, once concerned with starvation, predators, disease and other natural calamities, now worries about a whole new class of things. We must consciously adopt, as mankind's common goal, the same pursuit of excellence and variety from a basis of security by which Nature has guided us all along. Civilized man has removed himself from Nature's harsh but effective stewardship.
