“Plato by a goodly similitude declareth, why wise men refrain to meddle in the commonwealth. For when they see the people swarm into the streets, and daily wet to the skin with rain, and yet cannot persuade them to go out of the rain, they do keep themselves within their houses, seeing they cannot remedy the folly of the people.”

Variant: Some people feel the rain. Others just get wet!

"Einstein's Reply to Criticisms" (1949), The World As I See It (1949)
Context: There are few enough people with sufficient independence to see the weaknesses and follies of their contemporaries and remain themselves untouched by them. And these isolated few usually soon lose their zeal for putting things to rights when they have come face to face with human obduracy. Only to a tiny minority is it given to fascinate their generation by subtle humour and grace and to hold the mirror up to it by the impersonal agency of art. To-day I salute with sincere emotion the supreme master of this method, who has delighted — and educated — us all.

Professor Van Helsing to Dr. Seward
Dracula (1897)
Context: You reason well, and your wit is bold, but you are too prejudiced. You do not let your eyes see nor your ears hear, and that which is outside your daily life is not of account to you. Do you not think that there are things which you cannot understand, and yet which are, that some people see things that others cannot? But there are things old and new which must not be contemplated by men's eyes, because they know, or think they know, some things which other men have told them. Ah, it is the fault of our science that it wants to explain all, and if it explain not, then it says there is nothing to explain. But yet we see around us every day the growth of new beliefs, which think themselves new, and which are yet but the old, which pretend to be young, like the fine ladies at the opera.
