[7] Huxley: _Evolution and Ethics and Other Essays_, pp. 81-82. The
first two essays contained in this volume, the _Prolegomena_, and the
_Romanes Lecture_, contain a very interesting study of the relation of
morality to nature.

[8] Huxley: _Op. cit._, p. 13.

[9] G. K. Chesterton: _Napoleon of Notting Hill_, p. 291. The whole
book is a brilliant satire, intended to show that all of the heroic
sentiments and virtues depend on war and local pride.
