||YOUTH'S NEW FRONTIERS BETTER WORLD 23 to individual and social welfare. As ignorance of the law is no excuse, so ignorance of matters essential to harmonious human relations is inexcusable. A person, however, may be well informed and yet thoughtless in that he fails to exercise moral imagination, the habit of foreseeing the consequences, immediate and remote, of his conduct. The habit of being thoughtful of consequences of all types of conduct is more difficult to acquire than is the mere acquisition of knowledge. The habit of sympathetic understanding of others and acting always for their best good is still more difficult to acquire, yet it is most important of all. This conclusion is in agreement with the teachings of all the great spiritual leaders of mankind, and is confirmed in human experience through the ages. It has been said that "if we all sat at the same table no one would starve." But some people do starve because we lack the imagination to sense the suffering of starving thousands out of range of our immediate vision. Summary New frontiers for modern youth are primarily social or spiritual. Material things perish and are forgotten; the non-material or spiritual endure and enter into the social heritage of succeeding generations. Men and women of the future must center their ambitions on what they can do for the general welfare of their fellowmen. Each person is obligated to develop to the fullest his own natural endowments and to apply his abilities to the service of all. There will be need of those who have great ability in finance, commerce, and industry; these may serve their communities no less than others whose endowment is more distinctly academic or aesthetic, provided the financier, the captain of industry, and the director of commerce uses his abilities, not primarily for personal fame and fortune but as patriotic service. It is a slander on human nature to say in old frontier language that men of ability will have no incentive to put forth their best efforts unless they have prospect of personally reaping a fortune. George W. Goethals's magnificent achievement in building the Panama Canal was not for his own enrichment; Walter Reed had a finer incentive than money in his search for the cause of yellow fever The greatest needs of the world today are the further development of social intelligence, unbiased judgment and willingness to cooperate in unselfish, patriotic service. These characteristics American youth must cultivate in high degree if they would be successful in their quest and conquest of new frontiers.
