The age of nations has passed. Now, unless we wish to perish, we must shake off our old prejudices and build the Earth. The more scientifically I regard the world, the less can I see any possible biological future for it except in the active consciousness of its unity.

When scientifically investigating the natural world, the only thing worse than a blind believer is a seeing denier.

If you’re scientifically literate, the world looks very different to you, and that understanding empowers you.
