The deepest thing in any one is the conviction of the bad luck that follows boasting.

An irresistible passion that would induce me to believe in innate ideas and the truth of prophecy has decided my career. I have always loved liberty with the enthusiasm which actuates the religious man with the passion of a lover and with the conviction of a geometrician.

I have brought myself, by long meditation, to the conviction that a human being with settled purpose must accomplish it, and that nothing can resist a will which will stake even existence upon its fulfillment.

That deep emotional conviction of the presence of a superior reasoning power, which is revealed in the incomprehensible universe, forms my idea of God.

The secret of success is conviction and persistence.

Never give in, never give in, never, never, never, never-in nothing great or small, large or petty, never give in except to convictions of honour and good sense. Never yield to force; never yield to the apparently overwhelming might of the enemy.

The compensation of a very early success is a conviction that life is a romantic matter. In the best sense one stays young.

In the age-old contest between popularity and principle, only those willing to lose for their convictions are deserving of posterity’s approval.

The greatest happiness of life is the conviction that we are loved; loved for ourselves, or rather, loved in spite of ourselves.
