He who pronounces anything to be impossible, outside of the field of pure mathematics, is wanting in prudence.
Francois Arago.
A learned pedant who laughs at the possible comes very near being an idiot. To purposely shun a fact, and turn one's back upon it with a supercilious smile, is to bankrupt Truth.
Victor Hugo.
Science is under bonds, by the eternal principles of honor, to look fearlessly in the face every problem that is presented to her.
