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. ”
