Professor H. L. Van Breda had hoped to write this preface, but his recent, unexpected and untimely death has left that task in my hands. Although my remarks will not be as eloquent and insightful as his surely would have been, some few words are clearly in order here; for the phenomenological community has not only lost the leadership of Fr. Van Breda these last years, but also the scholarship and leadership of Aron Gurwitsch and Alden Fisher - both contributors to this volume - as well as that of Dorion Cairns and John Wild. Our leaders are fewer now but Herbert Spiegelberg is still very obviously one of them. This volume thus presents the work of some of the past and presently recognized leaders in phenomenology - e. g. Gurwitsch, Straus, and Fisher - but, more important perhaps, it also presents the work of some of those who are sure to be future leaders of our community of phenomenological philosophers, if in fact they have not already achieved this status. Most, if not all, of the contribu­ tors to this volume are in some way or another indebted to Herbert Spiegelberg and his work in phenomenology.
