W. R. Washington (William Robert Washington) Sullivan

W. R. Washington Sullivan, also listed as William Robert Washington Sullivan, is the author of Morality as a Religion: An Exposition of Some First Principles, first published in 1898. Surviving catalog and ebook records consistently connect him with that book, but readily available biographical details about his life appear to be scarce.

His work takes up a thoughtful late-Victorian question: whether morality can serve as the foundation of religion rather than merely follow from it. The book is remembered as a philosophical and ethical study, and it has remained accessible through public-domain libraries and reprints.

Because reliable sources uncovered here focus almost entirely on the book rather than the man, it is safest to describe Sullivan as an author known through this single surviving publication rather than through a well-documented public biography.
