"The history of human thought recalls the swinging of a pendulum which takes centuries to swing. After a long period of slumber comes a moment of awakening. Then thought frees herself from the chains with which those interested - rulers, lawyers, clerics - have carefully enwound her.
She shatters the chains. She subjects to severe criticism all that has been taught her, and lays bare the emptiness of the religious political, legal, and social prejudices amid which she has vegetated. She starts research in new paths, enriches our knowledge with new discoveries, creates new sciences. But the inveterate enemies of thought - the government, the lawgiver, and the priest - soon recover from their defeat. By degrees they gather together their scattered forces, and remodel their faith and their code of laws to adapt them to the new needs."

"I have no problem traveling alone. I’ve done it many times and if I had to wait on my friends all the time, I’d never go anywhere."
