"The science of criminology is pursued vigorously among the Italians, but this is one of the first English books to make the phenomena of crime the subject of a strictly scientific investigation."—Daily Chronicle.  
"The book is an important addition to the Social Science Series. It throws light upon some of the most complex problems with which society has to deal, and incidentally affords much interesting reading."—Manchester Examiner.
 
"This is a work which, considering its limits and modest pretensions, it is difficult to over praise. It is a calm and thoughtful study by a writer in whom the deliberate determination to look on things as they are has not extinguished a reasoned faith in the possibility of their amelioration. The work is conceived throughout in a genuinely philosophical spirit."—International Journal of Ethics.
 
"A thoughtful and thought suggesting book—well worthy of consideration by penologists, whether specialists or amateurs."—Annals of the American Academy.
 
"Mr. Morrison's book is especially valuable, because, without attempting to enforce this or that conclusion, it furnishes the authentic data on which all sound conclusions must be based."—Times.
 
"Cramful of suggestive facts and solid arguments on the great questions how criminals are made, and how crime is best to be dealt with. Many cherished superstitions and fallacies are exploded in Mr. Morrison's pages."—Star.
