If we treasure our own experience and regard it as real, we must also treasure other people's experience. Reality is no less precious if it presents itself to someone else. All are discoverers, and if we disenfranchise any, all suffer.

Some dreamers demand that scientists only discover things that can be used for good. That is impossible. Science gives us a powerful vocabulary, and it is impossible to produce a vocabulary with which one can only say nice things.
