When we consider the evils in the lives we know of, we find that they may be roughly divided into three classes. There are, first, those due to physical nature: among these are death, pain and the difficulty of making the soil yield a subsistence. These we will call ``physical evils.'' Second, we may put those that spring from defects in the character or aptitudes of the sufferer: among these are ignorance, lack of will, and violent passions. These we will call ``evils of character.'' Third come those that depend upon the power of one individual or group over another: these comprise not only obvious tyranny, but all interference with free development, whether by force or by excessive mental influence such as may occur in education. These we will call ``evils of power.'' A social system may be judged by its bearing upon these three kinds of evils. The distinction between the three kinds cannot be sharply drawn. Purely physical evil is a limit, which we can never be sure of having reached: we cannot abolish death, but we can often postpone it by science, and it may ultimately become possible to secure that the great majority shall live till old age; we cannot wholly prevent pain, but we can diminish it indefinitely by securing a healthy life for all; we cannot make the earth yield its fruits in any abundance without labor, but we can diminish the amount of the labor and improve its conditions until it ceases to be an evil. Evils of character are often the result of physical evil in the shape of illness, and still more often the result of evils of power, since tyranny degrades both those who exercise it and (as a rule) those who suffer it. Evils of power are intensified by evils of character in those who have power, and by fear of the physical evil which is apt to be the lot of those who have no power. For all these reasons, the three sorts of evil are intertwined. Nevertheless, speaking broadly, we may distinguish among our misfortunes those which have their proximate cause in the material world, those which are mainly due to defects in ourselves, and those which spring from our being subject to the control of others. The main methods of combating these evils are: for physical evils, science; for evils of character, education (in the widest sense) and a free outlet for all impulses that do not involve domination; for evils of power, the reform of the political and economic organization of society in such a way as to reduce to the lowest possible point the interference of one man with the life of another. We will begin with the third of these kinds of evil, because it is evils of power specially that Socialism and Anarchism have sought to remedy. Their protest against Inequalities of wealth has rested mainly upon their sense of the evils arising from the power conferred by wealth. This point has been well stated by Mr. G. D. H. Cole:-- What, I want to ask, is the fundamental evil in our modern Society which we should set out to abolish?
