Giovanni Papini,
Four and Twenty Minds
(1922)
“ For I believe that it is not enough, even in the field of philosophy, to know a theory. One must live it and feel it with all one's soul, must fill one's thought with it, must make it, for the time being, the content, the coloring and the significance of one's whole life. Berkeley's principle lends itself excellently well to this integral possession of truth. When a man truly discovers the great principle—and that may be long after he has known it at second hand—he is seized by a sort of idealistic intoxication which transforms the whole world for him. ”
