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 labour, but we can diminish the amount of the labour 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,
