At the approach of danger two voices speak with equal force in the heart of man: one very reasonably tells the man to consider the nature of the danger and the means of avoiding it and the other, even more reasonable, says that it is too painful and harassing to think of the danger... better to turn aside from the painful subject till it has come, and to think of what is pleasant. In solitude a man generally yields to the first voice; in society to the second.
