“Fear is only an enemy of those who have not learned to befriend its cause.”

“or he who innovates will have for his enemies all those who are well off under the existing order of things, and only lukewarm supporters in those who might be better off under the new. This lukewarm temper arises partly from the fear of adversaries who have the laws on their side, and partly from the incredulity of mankind, who will never admit the merit of anything new, until they have seen it proved by the event. The result, however, is that whenever the enemies of change make an attack, they do so with all the zeal of partisans, while the others defend themselves so feebly as to endanger both themselves and their cause.”

“One extraordinary thing happened as a result of the fear caused by your people, and that was that old feuds and envies disappeared. Those among us who had been enemies for generations forgot their grudges and joined one another against the invasion.”

“It's strange, but once you learn to fight, you seem to attract enemies...Sooner or later, those who master the art of combat must end up fighting.”

“Be loyal only to those who deserve it, and those who fear evil need not fear except from fear itself.”

“It is easy enough to be friendly to one's friends. But to befriend the one who regards himself as your enemy is the quintessence of true religion. The other is mere business.”
