Science tells us how to heal and how to kill; it reduces our death rate in retail and then kills us wholesale in war; but only wisdom - desire coordinated in the light of all experience - can tell us when to heal and when to kill.
Will DurantThe failure of the Reformation to capture France had left for Frenchmen no half-way house between infallibility and infidelity; and while the intellect of Germany and England moved leisurely in the lines of religious evolution, the mind of France leaped from the hot faith which had massacred the Huguenots to the cold hostility with which La Mettrie, Helvetius, Holbach, and Diderot turned upon the religion of the fathers.
Will DurantThe only real revolution is in the enlightenment of the mind and the improvement of character, the only real emancipation is individual, and the only real revolutionists are philosophers and saints.
