Reading, writing, thinking and investigating have all been crimes.Every science has been an outcast.All the altars and all the thrones united to arrest the forward march of the human race. The king said that mankind must not work for themselves. The priest said that mankind must not think for themselves. One forged chains for the hands, the other for the soul. Under this infamous regime the eagle of the human intellect was for ages a slimy serpent of hypo ”
