"Without knowledge there can be no sure progress. Vice and barbarism are the inseparable companions of ignorance. Nor is it too much to say that, except in rare instances, the highest virtue is attained only through intelligence."

I am convinced that everything that is worth while in the world has been accomplished by the free, inquiring, critical spirit, and that the preservation of this spirit is more important than any social system whatsoever. But the men of ritual and the men of barbarism are capable of shutting up the men of science and silencing them forever.
