Old men are dangerous it doesn't matter to them what is going to happen to the world. (George Bernard Shaw)
“So much good my persecutors have done me by recklessly pouring out all the shafts of their hatred. They have deprived themselves of any power over me and henceforward I can laugh at them. (Jean-Jacques Rousseau)"
We owe no morality to those who hold us under a gun. (Ayn Rand)
Take, say, the core of the established religions today: the Bible. It is basically polytheistic, with the warrior God demanding of his chosen people that they not worship the other Gods and destroy those who do -- in an extremely brutal way, in fact. It would be hard to find a more genocidal text in the literary canon, or a more violent and destructive character than the God who was to be worshipped. So that´s one definition. In the Prophets, one finds (sometimes) a different conception, much more humane. That´s why the Prophets (the "dissident intellectuals" of their day) were persecuted, imprisoned, driven into the desert, etc. -- other reasons included their geopolitical analysis, unwelcome to power. The intellectuals who were honored and privileged were those who centuries later were called "false prophets". (Noam Chomsky)
