Interesting and revolutionary as are the recent additions to philosophical physics brought about by the discovery of radium and its like, it is the other phase of this great physicist's mental trend which particularly interests the student of human behavior-- that wisdom which gives him (as it gave William James, and for a like reason), the bravery to look a bit beyond the more or less materialistic confines of mere science into the broader realm. And strange, is it not, that a man NEED be brave in this twentieth century Domini to discuss spiritism and survival and telepathy? Only those do it who cannot "lose their jobs." Can one indeed honestly doubt that many an intelligent psychologist to-day is kept from investigating this pressing phase of knowledge largely, or even solely, by the materialistic incubus whose continuance still stands for an academic salary usually sufficient to buy wife and children bread, if not a little meat? "Material bodies are all that we have any control over, are all that we are experimentally aware of; anything that we can do with these is open to us; any conclusions we can draw about them may be legitimate and true. But to step outside their province and to deny the existence of any other region because we have no sense-organs for its appreciation, or because (like the ether) it is too uniformly omnipresent for our ken, is to wrest our advantages and privileges from their proper use and apply them to our own misdirection." . . . "I am one of those who think that the methods of science are not so limited in their scope as has been thought: that they can be applied much more widely, and that the psychic region can be studied and brought under law too. Allow us anyhow to make the attempt. Give us a fair field. Let those who prefer the materialistic hypothesis by all means develop their thesis as far as they can; but let us try what we can do in the psychical region, and see which wins. Our methods are really the same as theirs--the subject-matter differs. Neither should abuse the other for making the attempt." Here is this matter in a nutshell, and the evolution of cosmology in the last few years makes this argument and this plea greatly more persuasive still, for it forges one more link in the actual knowledge of continuity. Twenty-four pages of useful, explanatory notes follow in this volume, the text of the Address. The book lacks an index. To those sapient ones who have not already saved the important little work out of Science, the dollar which this volume costs is a dollar well-spent, unless, indeed, philosophy be to him but a reproach.
