Whether we grow more gross, more selfish, more grasping, more vulgar, more dishonorable, or whether we grow more delicate, more tender, more sympathetic, more aspiring, or more affectionate does not depend on whether we think the mind quantitative or qualitative. It depends on what we think of the values of those qualities. And I for one choose so-called spiritual qualities of mind and character because for me they contain the most enduring and highest joys of earth. Therefore, in this practical sense I am a firm believer in the spiritual life. And when I use the term as I frequently do, it is in this sense that I use it.
