Doubt is a question mark; faith is an exclamation point. The most compelling, believable, realistic stories have included them both.

Many were the steps taken in doubt, that saw their shapeless ends in no time. Those who travail in faith today will truimph in joy tomorrow. Let faith lead the way.

It is debatable whether blind faith is truly faith at all. Faith is the perceptive gray area where scientific facts meet an individual's experiential truths - the extreme of the former is left feeling in the dark whereas the latter is caught blinded by the light. By proper scientific method, it is intellectually dishonest for me to declare the existence of God with utmost certainty, but to my individual spirit, I would be intellectually dishonest to deny the existence of God even for a second. This leaves the best of both worlds, as the believer is called to be able to give reasons for his faith, a deviation from mere fantasy.

Doubts we all have.

To have doubted one's own first principles, is the mark of a civilized man.

If you would be a real seeker after truth, it is necessary that at least once in your life you doubt, as far as possible, all things.

The more of doubt, the stronger faith, I say, If faith o'ercomes doubt.

Doubt is an incentive to truth and patient inquiry leadeth the way.

When you are in doubt abstain.

Cleave ever to the sunnier side of doubt.

Faith and doubt both are needed-not as antagonists but working side by side-to take us around the unknown curve.

... modest doubt is call'd The beacon of the wise.

If a man will begin with certainties, he shall end in doubts; but if he will be content to begin with doubts, he shall end in certainties.

If a man will begin with certainties he shall end in doubts; but if he will be content to begin with doubts he shall end in certainties.

The only thing I don't doubt is my doubt.

A proof tells us where to concentrate our doubts.

I am plagued by doubts. What if everything is an illusion and nothing exists? In that case, I definitely overpaid for my carpet. If only God would give me some clear sign! Like making a large deposit in my name at a Swiss bank.

Just think of the tragedy of teaching children not to doubt.

I respect faith, but doubt is what gets you an education.

The trouble with the world is that the stupid are cocksure and the intelligent are full of doubt.
