Study of thousands of children in all parts of this country, in England and in Germany, has shown that the young people begin to form ideal images of what they consider desirable, or beautiful, or right rather early in life. They form ideals of virtue as well as ideals of happiness, and these ideals reflect their experiences and their surroundings to a remarkable degree. Thus, there are differences between the ideals formed by country children and those formed by city children, between the ideals of poor children and those of wealthy ones, between the ideals of English children and those of American or German children. But, aside from all these differences, it is found that the ideals vary with the sex of the child, and also with the age, so that each child passes through a series of stages marked by characteristic types of ideals. As early as the age of nine years children have expressed themselves as looking forward to "doing good" in the world, or to making themselves "good." The age at which this impulse to service or to personal perfection may take form must depend upon many things besides the peculiar characteristics of the individual child. Jessie's ideals concerning "being good" will be shaped by what she hears and sees about her. If you speak frequently about the foreign missions, she may think of being good as something that has to do with the heathen. If the family conversation takes into consideration the sick and the needy, Jessie's ideal may be dressed like a Red Cross nurse. If you never speak of the larger problems of community welfare, or of social needs, or of moral advance in the home, where Robert has a chance to hear you, he can get suggestions toward such ideals only after he has read enough to become acquainted with these problems and the corresponding lines of service for himself.
