It is with a view to helping students of ethics in our universities and
outside of them to a clearer comprehension of the significance of morals
and the end of ethical endeavor, that this book has been written. 

I have, in the Notes appended to it, taken the liberty of making a few
suggestions to teachers, some of whom have fewer years of teaching behind
them than I have.  I make no apology for writing in a clear and
untechnical style, nor for reducing to a minimum references to
literatures in other tongues than our own.  These things are in accord
with the aim of the volume. 

I take this opportunity of thanking Professor Margaret F.  Washburn, of
Vassar College, and Professor F.  J.  E.  Woodbridge, of Columbia
University, for kind assistance, which I have found helpful. 

G.  S.  F.  New York, 1921.
