"In any age courage is the simple virtue needed for a human being to traverse the rocky road from infancy to maturity of personality. But in an age of anxiety, an age of herd morality and personal isolation, courage is a sine qua non. In periods when the mores of the society were more consistent guides, the individual was more firmly cushioned in his crises of development; but in times of transition like ours, the individual is thrown on his own at an earlier age and for a longer period."
