“He was a worshiper of liberty, a friend of the oppressed. A thousand times I have heard him quote these words: "For Justice all place a temple, and all season, summer." He believed that happiness is the only good, reason the only torch, justice the only worship, humanity the only religion, and love the only priest.”

“Justice is the only worship.Love is the only priest.Ignorance is the only slavery.Happiness is the only good.The time to be happy is now,The place to be happy is here,The way to be happy is to make others so.Wisdom is the science of happiness.”

“If you want to find out what a man is to the bottom, give him power. Any man can stand adversity — only a great man can stand prosperity. It is the glory of Abraham Lincoln that he never abused power only on the side of mercy”

“To hate man and worship God seems to be the sum of all the creeds.”

“Reason, Observation and Experience — the Holy Trinity of Science — have taught us that happiness is the only good; that the time to be happy is now, and the way to be happy is to make others so. This is enough for us. In this belief we are content to live and die. If by any possibility the existence of a power superior to, and independent of, nature shall be demonstrated, there will then be time enough to kneel. Until then, let us stand erect.”

“If the account given in Genesis is really true, ought we not, after all, to thank this serpent? He was the first schoolmaster, the first advocate of learning, the first enemy of ignorance, the first to whisper in human ears the sacred word liberty, the creator of ambition, the author of modesty, of inquiry, of doubt, of investigation, of progress and of civilization.”

“The doctrine that future happiness depends upon belief is monstrous. It is the infamy of infamies. The notion that faith in Christ is to be rewarded by an eternity of bliss, while a dependence upon reason, observation and experience merits everlasting pain, is too absurd for refutation, and can be relieved only by that unhappy mixture of insanity and ignorance, called 'faith.”
