When we of the so-called better classes are scared as men were never scared in history at material ugliness and hardship; when we put off marriage until our house can be artistic, and quake at the thought of having a child without a bank-account and doomed to manual labor, it is time for thinking men to protest against so unmanly and irreligious a state of opinion.
No society has ever yet been able to handle the temptations of technology to mastery, to waste, to exuberance, to exploration and exploitation. . . We have to learn to cherish this earth and cherish it as something that's fragile, that's only one, it's all we have. . . We have to use our scientific knowledge to correct the dangers that have come from science and technology.
