“There are in the world, two powers. The sword and the spirit. The spirit has always vanquished the sword.”

“There are but two powers in the world, the sword and the mind. In the long run the sword is always beaten by the mind”

“For the word of God is living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart.”

“There are two powers in the world; one is the sword and the other is the pen. There is a great competition and rivalry between the two. There is a third power stronger than both, that of the women.”

“I hope that you have nothing against malice, my good engineer. In my eyes it is the brightest sword that reason has against the powers of darkness and ugliness. Malice, sir, is the spirit of criticism, and criticism marks the origin of progress and enlightenment.”

“To prepare for the mountains develop mind, body, will and spirit as strong as a sword, soft as a pillow and fluid as water.”
