Follow your honest convictions and be strong.

A strong conviction that something must be done is the parent of many bad measures.

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.

When the intensity of emotional conviction subsides, a man who is in the habit of reasoning will search for logical grounds in favor of the belief which he finds in himself.

What we obtain too cheap, we esteem too lightly: it is dearness only that gives every thing its value. Heaven knows how to put a proper price upon its goods; and it would be strange indeed if so celestial an article as freedom should not be highly rated.

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

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

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

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.

The secret of success is conviction and persistence.

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

If you want to be successful, you must respect one rule: never lie to yourself.

When whole races and peoples conspire to propagate gigantic mute lies in the interest of tyrannies and shams, why should we care anything about the trifling lies told by individuals?

No matter how big the lie; repeat it often enough and the masses will regard it as the truth.

I have met men who are habitual liars. They have lied so long that they no longer can distinguish between the truth and a lie. Their sensitivity to sin has been almost completely deadened.

Self-control is strength. Right thought is mastery. Calmness is power.

Give us grace and strength to forbear and to persevere. Give us courage and gaiety and the quiet mind, spare to us our friends, soften to us our enemies.

Three passions, simple but overwhelmingly strong, have governed my life: the longing for love, the search for knowledge, and unbearable pity for the suffering of mankind.

Tenderness and kindness are not signs of weakness and despair, but manifestations of strength and resolution.

Our lives are like islands in the sea, or like trees in the forest. The maple and the pine may whisper to each other with their leaves . . . But the trees also commingle their roots in the darkness underground, and the islands also hang together through the ocean's bottom.

The strength and power of a country depends absolutely on the quantity of good men and women in it.

So it is more useful to watch a man in time of peril, and in adversity to discern what kind of man he is; for then at last words of truth are drawn from the depths of his heart, and the mask it torn off, reality remains.
