William Henry Chamberlin, The Study of Philosophy: An Outline (1919)
“ For when men either think or act, their ideas and acts are but manifestations of what are relatively very stable and persisting realities, the automatized interests or the attitudes that constitute his character. Such realities determine what one can select or know in the lives of others. But through the new ideas and acts thus arising and passing, the more persistent reality grows, creates more life or more reality, just as the leaves put forth by a vine in each new season of growth nourish a persisting and growing stem and then pass away. ”
