I have this theory that anything that happens to you that leaves you alive and intact can be used somewhere in your writing.
It is the theory which decides what we can observe
To say that Nature displays intelligence doesn't make you a Christian fundamentalist. Einstein said as much, and a fascinating theory called the anthropic principle has been seriously considered by Stephen Hawking, among others.
As the new endogenous growth theory suggests, TFP growth is closely related to accumulation of the intangible capitals, such as human capital and research and development.
Darwin based his theory on generalizations that were strictly empirical. You can go out and see that organisms do vary, that variations are inherited, and that every organism is capable of increasing its numbers in sufficiently favorable circumstances.
It's just something that I like, and I also don't buy into the ageism theory.
Smart technologies are not just disruptive; they can also preserve the status quo. Revolutionary in theory, they are often reactionary in practice.
Economists are people who wonder if what works in reality can also work in theory.
[Stéphane Mallarmé] theory of the hermetic is a mistake, but he can be only difficult to read when he has difficult things to say.
People love conspiracy theories.
Music is part of Number Theory. Nowadays when a number-theorist applies for a grant, he says that it is good for security, but in those days, way before America, he would say that it's good for music. I will not comment whether we have progressed.
Any attempt to define literary theory in terms of a distinctive method is doomed to failure.
Perfectly correct chess exists only in theory.
If a single one of these gentlemen is correct, if a believer of any type is right, the essential truth for man, the real drama of life, in comparison with which the secular story of the race, is a puppet-show and the unfolding of the universe is a triviality, is the dialogue of the immortal soul and the eternal God. Yet it seems that there is nothing in the world so hard to discover as this. The theory refutes itself.
Don't let anybody tell you that it's corporations and businesses that create jobs. You know that old theory, "trickle-down economics". That has been tried, that has failed. It has failed rather spectacularly.
That theory is worthless. It isn't even wrong!
Everything must be taken into account. If the fact will not fit the theory---let the theory go.
Men who believe too firmly in their theories, do not believe enough in the theories of others. So. . . these despisers of their fellows. . . make experiments only to destroy a theory, instead of to seek the truth.
Doesn't the theory of relativity concern literature too? In our world there is no longer any room for the privileged observer, as there is none for the observer of the universe - we are all within.
The theory of government changes with general progress.
