"Get your ideas on paper and study them. Do not let them go to waste!" 

An original idea. That can't be too hard. The library must be full of them.

In terms of how prudish Americans were in the '40s and '50s, I have absolutely no idea. I do know about the character that I play. And I don't think it's about being prudish. I think it's about trying to balance a sense of control in this man's life.

If every play was three weeks, I'd do lots of plays. It's just the idea of six months, I think, that might drive me a bit nuts.

There is no reason to suppose that the world had a beginning at all. The idea that things must have a beginning is really due to the poverty of our thoughts.

The only thing harder than getting a new idea into the military mind is to get an old one out.

We believed in our idea - a family park where parents and children could have fun- together.

The idea of regretting not doing this seemed insane to me. Sitting in the corner at a bar at age 60, saying: 'I could've been Bond. Buy me a drink.' That's the saddest place I could be. At least now at 60 I can say: 'I was Bond. Now buy me a drink.'

Once a man gets a fixed idea, there's nothing to be done.

“We shouldn't be looking for heroes, we should be looking for good ideas.” 

“Ideas are the source of all things” 

The only possible effect one can have on the world is through unpopular ideas.

Don’t get hung up on who owns the idea. Pick the best one, and let’s go.

An idea, by itself, it not erroneous but judgment makes it.

Any idea that is constantly held in the mind and emotionalized, begins at once to clothe itself in the most convenient and appropriate physical form that is available.

Ideas are the beginning of all achievement – in every industry, in every profession.

“She accused him of having grandiose ideas and sloppy habits, a fatal combination for a writer.” 

“There's always a moment when you start to fall out of love, whether it's with a person or an idea or a cause, even if it's one you only narrate to yourself years after the event: a tiny thing, a wrong word, a false note, which means that things can never be quite the same again.” 

“Now, the invention of the scientific method and science is, I'm sure we'll all agree, the most powerful intellectual idea, the most powerful framework for thinking and investigating and understanding and challenging the world around us that there is, and that it rests on the premise that any idea is there to be attacked and if it withstands the attack then it lives to fight another day and if it doesn't withstand the attack then down it goes. Religion doesn't seem to work like that; it has certain ideas at the heart of it which we call sacred or holy or whatever. That's an idea we're so familiar with, whether we subscribe to it or not, that it's kind of odd to think what it actually means, because really what it means is 'Here is an idea or a notion that you're not allowed to say anything bad about; you're just not. Why not? - because you're not!” 

“Pragmatism asks its usual question. "Grant an idea or belief to be true," it says, "what concrete difference will its being true make in anyone's actual life? How will the truth be realized? What experiences will be different from those which would obtain if the belief were false? What, in short, is the truth's cash-value in experiential terms?” 

Courage charms us, because it indicates that a man loves an idea better than all things in the world, that he is thinking neither of his bed, nor his dinner, nor his money, but will venture all to put in act the invisible thought of his mind.

We but half express ourselves, and are ashamed of that divine idea which each of us represents.

Those of us who submitted or surrendered our ideas and dreams and identities to the 'leaders' must take back our rights, our identities, our responsibilities.

When younger writers and poets, musicians and painters are weakened by a stemming of funds, they come to me saddened, not as full of dreams and excitement and ideas. I am then weakened and diminished, and made less rich.
