A person who doubts himself is like a man who would enlist in the ranks of his enemies and bear arms agains himself. He makes his failure certain by himself being the first person to be convinced of it.
Ambrose Bierce

A person who doubts himself is like a man who would enlist in the ranks of his enemies and bear arms against himself. He makes his failure certain by himself being the first person to be convinced of it.
Alexandre Dumas

A proof tells us where to concentrate our doubts.
Morris Kline

A reasonable doubt is nothing more than a doubt for which reasons can be given. The fact that 1 or 2 men out of 12 differ from the others does not establish that their doubts are reasonable.
Lord Hailsham

All around me insisted that my doubts proved only my own ignorance and sinfulness; that they knew by experience they would soon give place to true knowledge, and an advance in religion; and I felt something like indecision.
Maria Monk

All of this suggests that while citizens became more comfortable with President Bush after September 11 and thought him to have the requisite leadership skills, they continue to harbor doubts about his priorities, loyalties, interests, and policies.
Thomas E. Mann

All the strength and force of man comes from his faith in things unseen. He who believes is strong; he who doubts is weak. Strong convictions precede great actions.
James Freeman Clarke

An intellectual is going to have doubts, for example, about a fundamentalist religious doctrine that admits no doubt, about an imposed political system that allows no doubt, about a perfect aesthetic that has no room for doubt.
Antonio Tabucchi

And for mathematical science, he that doubts their certainty hath need of a dose of hellebore.
Joseph Glanvill

As a consequence of these hesitations and of the vague character of such innovations, the Commission on Human Rights itself had doubts from the beginning about its role and its functions in general.
Rene Cassin

Doubts are like stains on a shirt. I like shirts with stains, because when I'm given a shirt that's too clean, one that's completely white, I immediately start having doubts.
Antonio Tabucchi

Doubts raced through my mind as I considered the feasibility of enforcing a law which the majority of honest citizens didn't seem to want.
Eliot Ness

Face your fears and doubts, and new worlds will open to you.
Robert Kiyosaki

Faith keeps many doubts in her pay. If I could not doubt, I should not believe.
Henry David Thoreau

Faith, like a jackal, feeds among the tombs, and even from these dead doubts she gathers her most vital hope.
Herman Melville

He who believes is strong; he who doubts is weak. Strong convictions precede great actions.
Louisa May Alcott

I didn't have any doubts about my choice of career, but I had constant doubts about my ability, yes.
Suzanne Farrell

I don't have any doubts either about the Universal Declaration of Human Rights. Perhaps some more should be added to the list, but I don't have the slightest doubt about human rights.
Antonio Tabucchi

I have no doubts that it will be a major sport-in the United States. I'm probably not going to live to see that day because Americans are a little afraid of getting interested in something at which they're not very good.
Lamar Hunt

I love what I'm doing most of the time, but it's hard work. People only see your albums in the charts. They see us at award shows and after-show parties. They don't know about your doubts, the hard work that goes in.
Gavin Rossdale
