The sole philosophy open to those who doubt the possibility of truth is absolute silence - even mental.
It is easier to believe than to doubt.
Give a good deed the credit of a good motive; and give an evil deed the benefit of the doubt.
Men become civilized, not in proportion to their willingness to believe, but in proportion to their readiness to doubt.
Youth is not a time of life; it is a state of mind. People grow old only by deserting their ideals and outgrowing the consciousness of youth. Years wrinkle the skin, but to give up enthusiasm wrinkles the soul. You are as old as your doubt; your fear; your despair. The way to keep young is to keep your faith young. Keep your self-confidence young. Keep your hope young.
The road to resolution lies by doubt.
To believe is to be happy; to doubt is to be wretched. To believe is to be strong. Doubt cramps energy. Belief is power. Only so far as a man believes strongly, mightily, can he act cheerfully, or do any thing that is worth the doing.

Had I no other proof of the immortality of the soul than the oppression of the just and the triumph of the wicked in this world, this alone would prevent my having the least doubt of it. So shocking a discord amidst a general harmony of things would make me naturally look for a cause; I should say to myself we do not cease to exist with this life; everything reassumes its order after life.
Without doubt the greatest injury of all was done by basing morals on myth. For, sooner or later, myth is recognized for what it is, and disappears. Then morality loses the foundation on which it has been built.
Religion isn’t yours firsthand until you doubt it right down to the ground.
Doubt is not below knowledge, but above it.
Doubt is the accomplice of tyranny.
Doubt of the reality of love ends by making us doubt everything.
Lord, make me an instrument of Your peace. Where there is hatred let me sow love; where there is injury, pardon; where there is doubt, faith; where there is despair, hope; where there is darkness, light; and where there is sadness, joy.
For there are two modes of acquiring knowledge, namely, by reasoning and experience. Reasoning draws a conclusion and makes us grant the conclusion, but does not make the conclusion certain, nor does it remove doubt so that the mind may rest on the intuition of truth, unless the mind discovers it by the path of experience; since many have the arguments relating to what can be known, but because they lack experience they neglect the arguments, and neither avoid what is harmful nor follow what is good. For if a man who has never seen fire should prove by adequate reasoning that fire burns and injures things and destroys them, his mind would not be satisfied thereby, nor would he avoid fire, until he placed his hand or some combustible substance in the fire, so that he might prove by experience that which reasoning taught. But when he has had actual experience of combustion his mind is made certain and rests in the full light of truth. Therefore reasoning does not suffice, but experience does.
Doubt is an incentive to search for truth, and patient inquiry leads the way to it.
Who never doubted, never half believed. Where doubt is, there truth is - it is her shadow.
The dynamite of doubt is useful in wrecking old structures; but to build new buildings, we must have the dynamics of faith.
No fine work can be done without concentration and self-sacrifice and toil and doubt.
