One of the greatest pains to human nature is the pain of a new idea.
Walter Bagehot
Men may move mountains, but ideas move men.
Lois McMaster Bujold
There are no children of whom we are fonder than those that are born of our brains, to whom we are father and mother in one.
Jean Louis Guez de Balzac
Having lots of ideas doesn't mean you're clever, any more than having lots of soldiers means you're a good general.
Nicolas Chamfort
Ideas consume the ages as passions consume men. When man is cured, humanity may possibly cure itself.
Honor de Balzac
Ideas are more powerful than guns.
Anthony Neil Wedgwood Benn
You cannot force ideas. Successful ideas are the result of slow growth. Ideas do not reach perfection in a day, no matter how much study is put upon them.
Alexander Graham Bell
Nothing dies harder than a bad idea. And few ideas are worse than the ones we have about art.
Julia Cameron
Mathematics, in the development of its ideas, has only to take account of the immanent reality of its concepts and has absolutely no obligation to examine their transient reality.
Georg Ferdinand Ludwig Philipp Cantor
Ideas do not need weapons, to the extent that they can convince the great masses.
Fidel Alejandro Castro Ruz
Every new idea has something of the pain and peril of childbirth about it; ideas are just as mortal and just as immortal as organised beings are.
Samuel Butler
Ideas are like shadows , substantial enough until we try to grasp them.
Samuel Butler
