Without theory, practice is but routine born of habit. Theory alone can bring forth and develop the spirit of invention. ... [Do not] share the opinion of those narrow minds who disdain everything in science which has not an immediate application. ... A theoretical discovery has but the merit of its existence: it awakens hope, and that is all. But let it be cultivated, let it grow, and you will see what it will become.

Louis Pasteur

Theory without practice is of little value, whereas practice is the proof of theory.Theory is the knowledge, practice the ability.

Alois Podhajsky

I believe without exception that theory follows practice. Whenever there is a conflict between theory and practice, theory is wrong. As far as I'm concerned, we make theories for what people have done.

David Baker

There is a distinction, but no opposition, between theory and practice. Each to a certain extent supposes the other. Theory is dependent on practice; practice must have preceded theory.

Sir William Hamilton, 9th Baronet

Before going back to college, i knew i didn't want to be an intellectual, spending my life in books and libraries without knowing what the hell is going on in the streets. Theory without practice is just as incomplete as practice without theory. The two have to go together.

Assata Shakur

Theory without practice is just as incomplete as practice without theory.

The aim of academic trade theory is to tell students, "Look at the model, not at how nations actually develop." So of all the branches of economic theory, trade theory is the most wrongheaded.

Michael Hudson

Experience by itself teaches nothing... Without theory, experience has no meaning. Without theory, one has no questions to ask. Hence, without theory, there is no learning.

W. Edwards Deming

Critical reflection on practice is a requirement of the relationship between theory and practice. Otherwise theory becomes simply "blah, blah, blah, " and practice, pure activism.

Paulo Freire

In sum: banking theory and practice, as immobilizing and fixating forces, fail to acknowledge men and women as historical beings; problem-posing theory and practice take the people's historicity as their starting point.

Paulo Freire

Hey birthers, wanna hear my theory? My theory was that Obama was born in America and you were born with the umbilical cord around your neck.

Bill Maher

I don't think about a theory of everything when I do my research. And even if we knew the ultimate underlying theory, how are you going to explain the fact that we're sitting here? Solving string theory won't tell us how humanity was born.

Lisa Randall

In theory, practice should work like theory. In practice, it doesn't.

Yogi Berra

If the theory accurately predicts what they [scientists] see, it confirms that it's a good theory. If they see something that the theory didn't lead them to believe, that's what Thomas Kuhn calls an anomaly. The anomaly requires a revised theory - and you just keep going through the cycle, making a better theory.

Clayton Christensen

Theory is worth but little, unless it can explain its own phenomena, and it must effect this without contradicting itself; therefore, the facts are sometimes assimilated to the theory, rather than the theory to the facts.
