A house can have integrity, just like a person,' said Roark, 'and just as seldom.

It does take an exceptional mind and a still more exceptional integrity to remain untouched by the brain-destroying influences of the world’s doctrines, the accumulated evil of centuries—to remain human, since the human is the rational.

Integrity is the recognition of the fact that you cannot fake your consciousness, just as honesty is the recognition of the fact that you cannot fake existence.

A rational man never distorts or corrupts his own standards...in order to appeal to the irrationality, dishonesty or stupidity of others.

Integrity is the ability to stand by an idea.

Thousands of years ago the first man discovered how to make fire. He was probably burnt at the stake he'd taught his brothers to light, but he left them a gift they had not conceived and he lifted darkness from the face of the Earth.

Only a man of integrity can possess the virtue of honesty, since only the faking of one’s consciousness can permit the faking of existence.

There are two principles on which all men of intellectual integrity and good will can agree, as a 'basic minimum,' as a precondition of any discussion, co-operation or movement toward an intellectual Renaissance. . . . They are not axioms, but until a man has proved them to himself and has accepted them, he is not fit for an intellectual discussion. These two principles are: a. that emotions are not tools of cognition; b. that no man has the right to initiate the use of physical force against others.

There can be no compromise on basic principles. There can be no compromise on moral issues. There can be no compromise on matters of knowledge, of truth, of rational conviction.
