“No opinion is worth burning your neighbor for.”

“Such then is the human condition, that to wish greatness for one's country is to wish harm to one's neighbors.”

“Opinions have caused more ills than the plague or earthquakes on this little globe of ours. ”

“It is clear that the individual who persecutes a man, his brother, because he is not of the same opinion, is a monster.”

“What we find in books is like the fire in our hearths. We fetch it from our neighbors, we kindle it at home, we communicate it to others, and it becomes the property of all.”

“All the reasonings of men are not worth one sentiment of women”

“So it is the human condition that to wish for the greatness of one's fatherland is to wish evil to one's neighbors. The citizen of the universe would be the man who wishes his country never to be either greater or smaller, richer or poorer.”
