“I have always strenuously supported the right of every man to his own opinion, however different that opinion might be to mine. He who denies to another this right, makes a slave of himself to his present opinion, because he precludes himself the right of changing it.”

Christianity is the strangest religion ever set up, for it committed a murder upon Jesus in order to redeem mankind from the sin of eating an apple.

Our greatest enemies, the ones we must fight most often, are within.

Those who expect to reap the blessings of freedom must, like men, undergo the fatigue of supporting it.

Every person of learning is finally his own teacher.

Those who expect to reap the blessing of freedom must undertake to support it.

Reputation is what men and women think of us; character is what God and angels know of us.

When extraordinary power and extraordinary pay are allotted to any individual in a government, he becomes the center, round which every kind of corruption generates and forms.

A long habit of not thinking a thing wrong, gives it a superficial appearance of being right, and raises at first a formidable outcry in defense of custom. But the tumult soon subsides. Time makes more converts than reason.

Practical religion consists in doing good: and the only way of serving God is that of endeavoring to make His creation happy. All preaching that has not this for its object is nonsense and hypocrisy.

To argue with a person who has renounced the use of reason is like administering medicine to the dead.

There are two distinct classes of men – those who pay taxes and those who receive and live upon taxes.

It is error only, and not truth, that shrinks from inquiry.

It is the duty of every man, as far as his ability extends, to detect and expose delusion and error.

Reason and Ignorance, the opposites of each other, influence the great bulk of mankind. If either of these can be rendered sufficiently extensive in a country, the machinery of Government goes easily on. Reason obeys itself; and Ignorance submits to whatever is dictated to it.

We only stop growing when we resist change.

We all have a voice. If you take a stand, you could be changing someones life.

People do not change for other people. They will only change for themselves.

Can I doubt the shape of the earth? Can I judge a minute for lasting sixty seconds, a day for being grey or cold and leaves for falling from trees? Can I speak too loud when I am angry or stay quiet when I disagree? Can I forget about the norms and make some of my own?

And just like the leaves in the fall, she fell, too. And it changed her. And it was wonderful.

Once you bring life into the world, you must protect it. We must protect it by changing the world.

Help inspire people to realize they are capable of changing the world.

There are two primary choices in life: to accept conditions as they exist, or accept the responsibility for changing them.
