It is the incapacity of our thinking, the poverty of our perception, the vividness of our sense-experiences, and the encrustation of our habitual outlook which creates and maintains the illusion of the world's materiality and prevents us from noting that it is really a presence within consciousness. How can those who test reality like Dr. Johnson by using their feet or like any bricklayer by using their hands affirm any other doctrine than that of materialism? Contrarily, how can those who use their God-given intelligence to test reality arrive in the end at any other doctrine than that of mentalism? Those materialists who tell us today that the line of the soul is an unscientific one and that it is a legacy left to us by primitive simpletons are themselves unscientific and oversimple. For science, which began by repudiating mind and exalting matter, is being forced by facts to end by repudiating matter and exalting mind. This is why philosophy today must sharply emphasize and teach, alongside of ancient lore, the profounder mentalist import of vital facts of modern discovery which have not yet received their deserved reward of recognition from the world.
