“In order to have enough freedom, it is necessary to have too much.”

To say that the universe was here last year, or millions of years ago, does not explain its origin. This is still a mystery. As to the question of the origin of things, man can only wonder and doubt and guess.

I am simply an agnostic. I haven’t yet had time or opportunity to explore the universe, and I don’t know what I might run on to in some nook or corner.

You can only protect your liberties in this world by protecting the other man’s freedom.

The world is made up for the most part of morons and natural tyrants, sure of themselves, strong in their own opinions, never doubting anything.

The truth is always modern and there never comes a time when it is safe to give it voice.

Ancestors do not mean so much. The rebel who succeeds generally makes it easier for the posterity that follows him; so these descendants are usually contented and smug and soft. Rebels are made from life, not ancestors.

An agnostic is a doubter. The word is generally applied to those who doubt the verity of accepted religious creeds of faiths.

Laws should be like clothes. They should be made to fit the people they are meant to serve.

The fear of God is not the beginning of wisdom. The fear of God is the death of wisdom. Skepticism and doubt lead to study and investigation, and investigation is the beginning of wisdom.

The objector and the rebel who raises his voice against what he believes to be the injustice of the present and the wrongs of the past is the one who hunches the world along.

The best that we can do is to be kindly and helpful toward our friends and fellow passengers who are clinging to the same speck of dirt while we are drifting side by side to our common doom.

Great wealth often curses all who touch it.

One cannot live through a long stretch of years without forming some philosophy of life.

The purpose of man is like the purpose of a pollywog – to wiggle along as far as he can without dying; or, to hang to life until death takes him.

I am a friend of the working man, and I would rather be his friend, than be one.

Forgiveness is the key to action and freedom.

Freedom is the opposite of necessity.

The fruit of too much liberty is slavery.

The possession of power inevitably spoils the free use of reason.

My dreams were all my own; I accounted for them to nobody; they were my refuge when annoyed – my dearest pleasure when free.

Freedom is the source from which all significations and all values spring. It is the original condition of all justification of existence.

The main point of enlightenment is man’s release from his self-caused immaturity, primarily in matters of religion.

Freedom will bite back more fiercely when suspended than when she remains undisturbed.
