If cathedrals had been universities If dungeons of the Inquisition had been laboratories If Christians had believed in character instead of creed If they had taken from the bible only that which is GOOD and thrown away the wicked and absurd If temple domes had been observatories If priests had been philosophers If missionaries had taught useful arts instead of bible lore If astrology had been astronomy If the black arts had been chemistry If superstition had been science If religion had been humanity The world then would be a heaven filled with love, and liberty and joy

Hope is the only universal liar who never loses his reputation for veracity.

While I am opposed to all orthodox creeds, I have a creed myself; and my creed is this. 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. This creed is somewhat short, but it is long enough for this life, strong enough for this world. If there is another world, when we get there we can make another creed.

Our ignorance is God; what we know is science. When we abandon the doctrine that some infinite being created matter and force, and enacted a code of laws for their government ... the real priest will then be, not the mouth-piece of some pretended deity, but the interpreter of nature.

Logic is not satisfied with assertion. It cares nothing for the opinions of the great; nothing for the prejudices of the many, and least of all for the superstitions of the dead.

The intellectual advancement of man depends on how often he can exchange an old superstition for a new truth.

All should be taught that the highest ambition is to be happy, and to add to the well-being of others; that place and power are not necessary to success; that the desire to acquire great wealth is a kind of insanity. They should be taught that it is a waste of energy, a waste of thought, a waste of life, to acquire what you do not need and what you do not really use for the benefit of yourself or others.
