[editor’s foreword, describing Grant’s book, followed by Roosevelt’s endorsement]
The vast subject of the origin, relationship, evolution, migration, and expansion of European man is here considered in connection with the phenomena of the civilization to-day.
“The book is a capital book; in purpose, in vision, in grasp of the facts our people most need to realize. It shows an extraordinary range of reading and a wide scholarship. It shows a habit of singular serious thought on the subject of most commanding importance. It shows a fine fearlessness in assailing the popular and mischievous sentimentalities and attractive and corroding falsehoods which few men dare assail. It is the work of an American scholar and gentleman; and all Americans should be sincerely grateful to you for writing it.”
– Theodore Roosevelt
