The year 1959 has been called The Centennial Year in view of the anniversary of the publication of The Origin of SPecies and the centenary of the births of many who later contributed much to the philosophy of the recent past, such as Samuel Alexander, Henri Bergson, John Dewey and Edmund Husser!‘ The essays in the present volume which are on subjects germane to any of the anniversaries celebrated this year have been placed first in the present volume. CENTENNIAL YEAR NUMBER DARWIN AND SCIENTIFIC METHOD JAMES K. FEIBLEMAN The knowledge of methodology, which is acquired by means of formal education in the various disciplines, is usually com municated in abstract form.
