history and of evolutionary philosophy."
--_The Chicago Tribune._

"The question which most interests both Professor Giddings
and his readers is the application of his facts, his
sociology, and his prophecy, to the future of the American
Empire.... The reader will rise from it with a broader

his country."--_The Independent._

The Principles of Sociology

An Analysis of Phenomena of Association and of Social Organization
_8vo, Cloth, $3.00_

"It is a treatise which will confirm the highest expectations
of those who have expected much from this alert observer and
virile thinker. Beyond a reasonable doubt, the volume is the
ablest and most thoroughly satisfactory treatise on the
subject in the English language."--_Literary World._

"The distinctive merit of the work is that it is neither
economics nor history.... He has found a new field and

anthropology and ethnology are also fully and ably handled.

value. A useful book must be read to be understood."
--Professor SIMON N. PATTEN, in _Science_.

"It is thoroughly intelligent, independent, suggestive, and
manifests an unaffected enthusiasm for social progress, and
on the whole a just and sober apprehension of the conditions
and essential features of such progress."
--Professor H. SIDGWICK, in _The Economic Journal_.

"Of its extreme interest, its suggestiveness, its helpfulness
to readers to whom social questions are important, but who
have not time or inclination for special study, we can bear
sincere and grateful testimony."--_New York Times._
