"If you wish to make an apple pie from scratch, you must first invent the universe." ― Carl Sagan Topic(s): Nature More From Carl Sagan "A celibate clergy is an especially good idea, because it tends to suppress any hereditary propensity toward fanaticism." "We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces." "We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology." More In Nature "Nature and human life are as various as our several constitutions. Who shall say what prospect life offers to another?"― Henry David Thoreau "I have never felt salvation in nature. I love cities above all."― Michelangelo "Cultivation to the mind is as necessary as food to the body."― Marcus Tullius Cicero
