81:2.14

The savage is a slave to nature, but scientific civilization is slowly conferring increasing liberty on mankind. Through animals, fire, wind, water, electricity, and other undiscovered sources of energy, man has liberated, and will continue to liberate, himself from the necessity for unremitting toil. Regardless of the transient trouble produced by the prolific invention of machinery, the ultimate benefits to be derived from such mechanical inventions are inestimable. Civilization can never flourish, much less be established, until man has leisure to think, to plan, to imagine new and better ways of doing things.
