Welfare, in an immediate or narrow sense, is the same as gratification of the moment; in a broader sense, it means the abiding condition of well-being. We have here a distinction very much like that often made between pleasure and happiness. If we think of only the present moment, welfare is the absence of pain, and the presence of the pleasureable feeling; but if we consider a longer period in a man's life or his entire lifetime, it is seen that many things that afford a momentary gratification do not minister to his ultimate, or abiding, welfare. Moralists and philosophers often have dwelt on this contrast. The difference is illustrated by the thoughtlessness and impulsiveness of a child or savage as contrasted with the more rational life of those with foresight and patience. [Sidenote: Economics first studies wealth] Wealth, in the general economic sense, is judged with reference to gratification rather than with reference to abiding welfare. It is the first duty of the economist not to preach what should be, but to understand things as they are. He must, in studying the problem of value, recognize any motive that leads men to attach importance to acts and things. He will therefore take account of abiding welfare and of immediate gratification to exactly the degree that men in general do, and the sad fact is that the present impulse rules a large part of the acts of men. Whether tobacco or alcohol or morphine minister to the abiding happiness of those who use them does not alter the immediate fact that here and now they are sought and an importance is attached to them because of their power to gratify an immediate desire. [Sidenote: Then wealth and welfare] 5. _In studying the question of social prosperity, however, we must rise to the standpoint of the social philosopher and consider the more abiding effects of wealth._ Wants may be developed and made rational, and the permanent prosperity of a community depends upon this result. Any species of animal that continued regularly to enjoy that which weakens the health and strength would become extinct. Any society or individual that continues to derive gratification, to seek its pleasure, in ways that do not, on the average, minister to permanent welfare, sinks in the struggle of life and gives way to those men or nations that have a sounder and healthier adjustment of wants and welfare. We touch here, therefore, on the edge of the great problems of morals, and while we must recognize the contrast that often exists in the life of any particular man between his "pleasures" and his health and happiness, we see that there is a reason why, on the whole, and in the long run, these two cannot remain far apart. The old proverbs, "Be virtuous and you will be happy," "Honesty is the best policy," and "Virtue is its own reward," have a sound basis in the age-long experience of the world. Cynics or jesters may easily disprove these truths in a multitude of particular cases.
