Conviction

Happiness depends upon ourselves

A man who won't die for something is not fit to live

Don't take the wrong side of an argument just because your opponent has taken the right side.

Men willingly believe what they wish

Make it a rule never to give a child a book you would not read yourself.

Many people think that virtue consists of severity towards others

Patriotism is the conviction that your country is superior to all others because you were born in it.

The only faith that wears well and holds its color in all weathers is that which is woven of conviction and set with the sharp mordant of experience

That deep emotional conviction of the presence of a superior reasoning power, which is revealed in the incomprehensible universe, forms my idea of God

It is a kind of spiritual snobbery that makes people think they can be happy without money

It is through the idealism of youth that man catches sight of truth, and in that idealism he possesses a wealth which he must never exchange for anything else

The greatest happiness of life is the conviction that we are loved; loved for ourselves, or rather, loved in spite of ourselves

I would never die for my beliefs because I might be wrong

One must judge men not by their opinions, but by what their opinions have made of them

You have not converted a man because you have silenced him

Where so many hours have been spent in convincing myself that I am right, is there not some reason to fear I may be wrong?

Consider your origin; you were not born to live like brutes, but to follow virtue and knowledge

It is the greatest art of the devil to convince us he does not exist.

When I tell the truth, it is not for the sake of convincing those who do not know it, but for the sake of defending those that do.
