The mind, once stretched by a new idea, never regains its original dimensions.
There is nothing more powerful than an idea whose time has come.
The value of an idea lies in the using of it.
We shouldn't be looking for heroes, we should be looking for good ideas.
Ideals are like the stars: we never reach them, but like the mariners of the sea, we chart our course by them.
I had no idea that being your authentic self could make me as rich as I've become. If I had, I'd have done it a lot earlier.
I keep my ideals, because in spite of everything I still believe that people are really good at heart.
I am an idealist. I don't know where I'm going but I'm on my way.
A man may die, nations may rise and fall, but an idea lives on. Ideas have endurance without death.
I'm completely in favor of the separation of Church and State. My idea is that these two institutions screw us up enough on their own, so both of them together is certain death.
Our ideals, like pictures, are made from lights and shadows.
A perfect human being: Man in search of his ideal of perfection. Nothing less.
When they come downstairs from their Ivory Towers, idealists are very apt to walk straight into the gutter.
Many ideas grow better when transplanted into another mind than in the one where they sprung up.
There is one thing stronger than all the armies in the world, and that is an idea whose time has come.
