Bigot, n. One who is obstinately and zealously attached to an opinion that you do not entertain.

The man who never alters his opinion is like standing water, and breeds reptiles of the mind.

It is in the uncompromisingness with which dogma is held and not in the dogma or want of dogma that the danger lies.

There are two kinds of people in the world: the conscious dogmatists and the unconscious dogmatists. I have always found myself that the unconscious dogmatists were by far the most dogmatic.

We call a man a bigot or a slave of dogma because he is a thinker who has thought thoroughly and to a definite end.

Religion is as effectually destroyed by bigotry as by indifference.

We are least open to precise knowledge concerning the things we are most vehement about.

No man should dogmatize except on the subject of theology. Here he can take his stand, and by throwing the burden of proof on the opposition, he is invincible. We have to die to find out whether he is right.

Profound ignorance makes a man dogmatic. The man who knows nothing thinks he is teaching others what he has just learned himself; the man who knows a great deal can't imagine that what he is saying is not common knowledge, and speaks more indifferently.

How strange it is to see with how much passion People see things only in their own fashion!
