It made me what I am. - William Winwood Reade

Industry is the only true source of wealth, and there was no industry in Rome. By day the Ostia road was crowded with carts and muleteers, carrying to the great city the silks and spices of the East, the marble of Asia Minor, the timber of the Atlas, the grain of Africa and Egypt; and the carts brought nothing out but loads of dung. That was their return cargo. London turns dirt into gold. Rome turned gold into dirt.

All doctrines relating to the creation of the world, the government of man by superior beings, and his destiny after death, are conjectures which have been given out as facts, handed down with many adornments by tradition, and accepted by posterity as "revealed religion". They are theories more or less rational which uncivilised men have devised in order to explain the facts of life, and which civilised men believe that they believe.

Doubt is the offspring of knowledge: the savage never doubts at all.
