“In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.”
― Carl Sagan

“The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.”
― Isaac Asimov

“Knowing others is intelligence;
knowing yourself is true wisdom.
Mastering others is strength;
mastering yourself is true power.”
― Lao Tzu, Tao Te Ching

“A man is a success if he gets up in the morning and gets to bed at night, and in between he does what he wants to do.”
― Bob Dylan
