The intellect has no right to chide the enjoyments of the senses. Pleasures differ in degree and permanence, but not in kind. _As pleasures_ they are on a par, whether derived from objects of sense, from the emotions, or from the understanding. Such analysts of mind as Kant and Epictetus agree that there is no _essential_ distinction between the most refined and the coarsest gratifications. “It is one and the same vital force expressing itself in the Desires, which is affected by all objects which cause Pleasure.” IV. _The Distribution of Happiness._ Having reached an understanding about what happiness means, and some notion as to its various grades, it will next be worth while to study its distribution in the several classes of society, in contrasting grades of civilization, in the two sexes, and at various ages. This will be dealing with the subject according to the methods of natural science, and it ought to lead to some interesting conclusions. One might expect to find a general agreement as to the main facts. Far from it. The common belief is that happiness increases with the means, or at least with the capacity, for happiness. It is this belief which inspires men to labor for the means and improve their capacities. But the philosophers nowise concede its correctness. Hume argued that all who are happy are equally happy; and Paley maintained that happiness is about equally distributed among all orders of the community; that the plowman gets as much real enjoyment out of life as the philosopher, and the beggar at the gate as much as the monarch on the throne. To which Dr. Johnson replied that a small glass and a large one might be equally full, but the latter holds more. The capacity, he justly argued, of the philosopher to receive a multiplicity of agreeable impressions is greater than that of the peasant, and therefore, other things being equal, the quantity of his enjoyment will be greater. The learned Doctor, indeed, sometimes insisted that felicity increases directly with the means of enjoyment. Representing the latter by money, he would say that a man with six thousand pounds a year should be ten times as happy as the one with six hundred a year; and if he is not, it is because he is an ass. Here he was certainly wrong. Some of the main elements of ordinary happiness are in the possession of every class of society, high and low, poor and rich; such as the means of self-preservation, family ties, friendship, amusement, and repose. What wealth and power add to this common stock becomes less and less at each remove. This consideration led Bentham to question whether the prince is twice as happy as the laborer, and to doubt whether ten thousand times the wealth brings with it twice the enjoyment. His followers have attempted to frame the relation in a mathematical formula, and have expressed it in the maxim, “The rate of increase of pleasure decreases as its means increase.”
