“It is science alone that can solve the problems of hunger and poverty, of insanitation and illiteracy, of superstition and deadening custom and tradition, of vast resources running to waste, or a rich country inhabited by starving people... Who indeed could afford to ignore science today? At every turn we have to seek its aid... The future belongs to science and those who make friends with science.”

“Ignorance more frequently begets confidence than does knowledge: it is those who know little, not those who know much, who so positively assert that this or that problem will never be solved by science.”

“By and large, people who choose to go into science are not greatly interested in psychological problems... He liked the exactness of science, and the perfection of its truths - Humanity could be rather messy in comparison.”

“As science pushes forward, ignorance and superstition gallop around the flanks and bite science in the rear with big dark teeth.”

“Science is the key to our future, and if you don’t believe in science, then you’re holding everybody back. And it’s fine if you as an adult want to run around pretending or claiming that you don’t believe in evolution, but if we educate a generation of people who don’t believe in science, that’s a recipe for disaster. We talk about the Internet. That comes from science. Weather forecasting. That comes from science. The main idea in all of biology is evolution. To not teach it to our young people is wrong.”

“Your only real problem is mortality! No religion can solve this problem, but science can do!”
