Who said “We should be eternally vigilant against attempts to check the expression of opinions…”?

“Where an opinion is general, it is usually correct.”

“The foolish and the dead alone never change their opinions.”

“Opinions cannot survive if one has no chance to fight for them.”

“We accumulate our opinions at an age when our understanding is at its weakest.”

“Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric.”

“Life is painting a picture, not doing a sum.”

“I have no respect for the passion of equality, which seems to me merely idealizing envy.”

“Life is an end in itself, and the only question as to whether it is worth living is whether you have had enough of it.”

“Most of the things we do, we do for no better reason than that our father's have done them or our neighbors do them, and the same is true of a large part than what we suspect of what we think.”

“With all humility, I think, ''Whatsoever thy hand findeth to do, do it with thy might.'' Infinitely more important than the vain attempt to love one's neighbor as one's self. If you want to hit a bird on the wing, you must have all your will in focus, you must not be thinking about yourself, and equally, you must not be thinking about your neighbor: you must be living in your eye on that bird. Every achievement is a bird on the wing.”

“Carve every word before you let it fall.”
