Intellect, without heart, is infinitely cruel. . . . So that, after all, the real aristocracy must be that of goodness where the intellect is directed by the heart.
Robert Green IngersollThe intellectual advancement of man depends on how often he can exchange an old superstition for a new truth.
Robert Green IngersollA believer is a bird in a cage, a freethinker is an eagle parting the clouds with tireless wing.
Robert Green IngersollThe Christians say, that among the ancient Jews, if you committed a crime you had to kill a sheep. Now they say 'charge it.' 'Put it on the slate.' The Savior will pay it. In this way, rascality is sold on credit, and the credit system in morals, as in business, breeds extravagance.
