Men ought either to be indulged or utterly destroyed, for if you merely offend them they take vengeance, but if you injure them greatly they are unable to retaliate, so that the injury done to a man ought to be such that vengeance cannot be feared. – Niccolo Machiavelli
I will not attack your doctrines nor your creeds if they accord liberty to me. If they hold thought to be dangerous – if they aver that doubt is a crime, then I attack them one and all, because they enslave the minds of men. – Robert Green Ingersoll
In science, “fact” can only mean “confirmed to such a degree that it would be perverse to withhold provisional assent.” I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms. – Stephen J. Gould
