Nothing could be more dangerous to the existence of this Republic than to introduce religion into politics

Every man is dishonest who lives upon the labor of others, no matter if he occupies a throne.

If abuses are destroyed, man must destroy them. If slaves are freed, man must free them. If new truths are discovered, man must discover them. If the naked are clothed; if the hungry are fed; if justice is done; if labor is rewarded; if superstition is driven from the mind; if the defenseless are protected, and if the right finally triumphs, all must be the work of man. The grand victories of the future must be won by man, and by man alone.

The way to be happy is to make others so.

[T]he blossom of benevolence, of charity, is the fairest flower, no matter whether it blooms by the side of a hovel, or bursts from a vine climbing the marble pillar of a palace. I respect no man because he is rich; I hold in contempt no man because he is poor.

There is something wrong in a government where they who do the most have the least. There is something wrong when honesty wears a rag, and rascality a robe; when the loving, the tender, east a crust, while the infamous sit at banquets.

Every church that has a standard higher than human welfare is dangerous.
