The [peppered-moth] experiments show the effects of predation on the survival of the dark and of the normal forms of the Peppered Moth in a clean environment and in one polluted by smoke. The experiments beautifully demonstrate natural selection--or survival of the fittest--in action, but they do not show evolution in progress, for however the population may alter in their content of light, intermediate or dark forms, all the moths remain from beginning to end Biston Betularia.

The Art of Success. . . Success is ninety-nine percent mental attitude. It calls for love, joy, optimism, confidence, serenity, poise, faith, courage, cheerfulness, imagination, initiative, tolerance, honesty, humility, patience, and enthusiasm. . . . Success is having the courage to meet failure without being defeated. It is refusing to let present loss interfere with your long-range goal. . . . Success is relative and individual and personal. It is your answer to the problem of making your minutes, hours, days, weeks, months, and years add up to a great life.
