It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's wrong.

When you look at any experimental work not directly related to economics, but trying to test rational behavior in other ways, experiments have conspicuously failed to show rational behavior. Macro evidence certainly suggests deviations from rationality, but I don't want to say the rationality hypothesis is completely wrong. If you have any introspective idea or experimental idea about people's behavior, it seems to be incompatible with the really full scale rational expectations.
I write constantly, so it flows from one project to the next, and I would edit everything endlessly if I had the chance. I can always see ways to improve what I've done. At the same time, knowing it's all an ongoing life's work allows me to be less precious about blind alleys, failed experiments, and misfires.
As believers in democracy we have not only the right but the duty to question existing mechanisms of, say, suffrage and to inquire whether some functional organization would not serve to formulate and manifest public opinion better than the existing methods.

Science rests on reason and experiment, and can meet an opponent with calmness; [but] a creed is always sensitive.
The true worth of an experimenter consists in his pursuing not only what he seeks in his experiment, but also what he did not seek.
I get to experiment with a lot of looks with my character so that's really fun for me. It's like getting to paint a new canvas everyday.
America is the most grandiose experiment the world has seen, but, I am afraid, it is not going to be a success.
I have nothing new to teach the world. Truth and Non-violence are as old as the hills. All I have done is to try experiments in both on as vast a scale as I could.

If you want to understand the nature of something, to find out the truth, that is one thing. If you want to play semantics, make up wild thought 'experiments', that is another thing. I am not so interested in the latter, though I do appreciate that it can be fun, however unproductive.
