Edward O. Sisson said this quote

The deepest-lying and most pervasive part of character is disposition: it accompanies us everywhere, and shows itself in all we do. It is the attitude of the soul toward life, the way in which we accept our situation and our daily experiences. On the inner side it gives color and tone to our own conscious life: on the outer side it pervades and modifies our conduct toward others and our reactions to events. A good disposition is indispensable to good character, though of course not all of character; without it one cannot hope for perfection; even with it one may fail through lack of higher elements. It is a sort of foundation layer.

Every man whose tastes have been allowed to develop in wrong directions, or in whom the best tastes have failed of higher perfection, loses thereby from the inner joy and outer value of his whole life. Every good taste is a source and guarantee of happy healthy hours and days, and thus of the enrichment and elevation of life. A reasonable capacity to appreciate music and art quite suffices to enrich life and exercise a wholesome influence upon character. The taste for good reading is inseparable from a taste for good thinking.

A certain bygone philosophy-which certainly must have quite forgotten all about the real child-used to speak of the child's nature as a tabula rasa, or 'blank page,' upon which experience and training might write what they pleased. As a matter of fact, the child's nature at birth, like that of a calf or a chick, is pretty well scribbled over by the experience of its ancestors. It is far from being blank, for as soon as the little organism comes into the world, it begins to do certain things and do them with much zeal and determination, as every one knows who knows real children.

In one sense the whole process of development consists of the formation of habits; for knowledge itself, and the powers of thought, as well as the higher elements in the will, all depend upon the establishment of fixed ways of reacting to given stimuli. Consequently, the general laws of habituation underlie the whole of education. But the term habit is more commonly restricted to those established reactions that act with little or no participation of consciousness, or, in other words, mechanically or automatically. Such habits as these begin to form very early, and constitute a kind of supporting framework for the higher elements of character.
