At the present day the crude theory of the sexual impulse held on one side, and the ignorant rejection of theory altogether on the other side, are beginning to be seen as both alike unjustified.

Mr. DeMille's theory of sexual difference was that marriage is an artificial state for women. The want to be taken, ruled, raped. That was his theory.

Classic economic theory, based as it is on an inadequate theory of human motivation, could be revolutionized by accepting the reality of higher human needs, including the impulse to self actualization and the love for the highest values.

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.

A theory is only as good as its assumptions. If the premises are false, the theory has no real scientific value. The only scientific criterion for judging the validity of a scientific theory is a confrontation with the data of experience.

On His Father's Side
On his mother’s side
Born in Bethlehem
On his Father’s side
No one before him
On his mother’s side
Growing and learning
On his Father’s side
All knowledge showing
On his mother’s side
Stuck in one location
On his Father’s side
Present in every nation
On his mother’s side
He was hungry
On his Father’s side
The multitudes he did feed
On his mother’s side
At Calvary he died
On his Father’s side
He was the essence of life
On his mother’s side
Buried like other men
On his Father’s side
He rose again
On his mother’s side
Human and weak
On his Father’s side
The God of eternity.

Don't confuse hypothesis and theory. The former is a possible explanation; the latter, the correct one. The establishment of theory is the very purpose of science.

In the book, I make the point that here we have string theory and here we have twistor theory and we don't know if either one of them is the right approach to nature.

They didn't accept me theory - not a theory, but just a thought I had about this character. I noticed that this man only exists when the boy comes into the grocery.

Every theory presented as a scientific concept is just that; it's a theory that tries to explain more about the world than previous theories have done. It is open to being challenged and to being proven incorrect.
