Science may be described as the art of systematic over-simplification.

No rational argument will have a rational effect on a man who does not want to adopt a rational attitude.

Those who promise us paradise on earth never produced anything but a hell.

There is no history of mankind, there are only many histories of all kinds of aspects of human life. And one of these is the history of political power. This is elevated into the history of the world.

It is impossible to speak in such a way that you cannot be misunderstood.

Piecemeal social engineering resembles physical engineering in regarding the ends as beyond the province of technology.

Science must begin with myths, and with the criticism of myths.

Whenever a theory appears to you as the only possible one, take this as a sign that you have neither understood the theory nor the problem which it was intended to solve.

We have become makers of our fate when we have ceased to pose as its prophets.

Our knowledge can only be finite, while our ignorance must necessarily be infinite.

We may become the makers of our fate when we have ceased to pose as its prophets.

It is complete nihilism to propose laying down arms in a world where atom bombs are around. It is very simple: there is no way of achieving peace other than with weapons.

I try to ground most of my characters in reality somehow. That's kind of what I bring to the table.

Generally students are the best vehicles for passing on ideas, for their thoughts are plastic and can be molded and they can adjust the ideas of old men to the shape of reality as they find it in villages and hills of China or in ghettos and suburbs of America.

Without art, the crudeness of reality would make the world unbearable.

We must admit with humility that, while number is purely a product of our minds, space has a reality outside our minds, so that we cannot completely prescribe its properties a priori.

In reality, the most important things happen when you don't look for them.

What I would have liked to do on that show was play a secretary of state who has huge personal business interests throughout the world. That, to me, seems to be more in synch with reality.

From a reality perspective, I'm sure part of that is true, but this is the largest blackout in U.S. history. If that is not a signal that we have got a problem that needs to be fixed, I don't know what is.

Some theists in evolutionary science acquiesce to these tacit rules and retain a personal faith while accepting a thoroughly naturalistic picture of physical reality.

Religion, you know, enters very deep; in reality it is the deepest impression I have in speaking to people, that they are or that they are not of my religion.

I refuse to accept the view that mankind is so tragically bound to the starless midnight of racism and war that the bright daybreak of peace and brotherhood can never become a reality... I believe that unarmed truth and unconditional love will have the final word.

You can close your eyes to reality but not to memories.

Sometimes I read a script and it's obvious from early on that it's one where the suspension of disbelief has to develop strongly from page one. Some are more reality-based.
