The remarks on the State in Chapter XXIII are, as far as they go, judicious; but we could have wished that the author, who we are sure desires to make his treatise as practically useful as possible, had dwelt somewhat on the dangers of over-legislation, and had brought into fuller relief than he has done the difference between state action and voluntary enterprise, arising from the fact that the former always involves the element of _compulsion_. We pass a law when we can not get our neighbor to co-operate or agree with us in something, and consequently resolve to compel him. Surely this consideration should suffice to make parsimony the first principle of legislation. We agree with our author that it is not well to "belittle" the state (page 214), but it is hardly belittling the state to wish to be very sparing in our appeals to it for the exercise of coercive power. We miss also in the work before us such a treatment of the _family_ as might have been introduced into it with advantage. The family certainly has an important relation to the individual, and in all civilized countries it is specially recognized by the state. Mr. Spencer, in the chapter of his Study of Sociology entitled Preparation in Psychology, has dwelt on the encroachments of the state on the family; and Mr. Pearson, in his National Life and Character, published half a dozen years ago, sounded a note of alarm on the same subject. What position Professor Giddings would have taken as to the importance of family life and the rights and duties of the family we do not, of course, know; but we are disposed to think he could have increased the usefulness and interest of his book by some discussion of these points. We would only further say that, while the book is specially intended for scholastic use, it is well adapted for general reading, and that it could not be read carefully by any one without profit. * * * * * Prof. _Wesley Mills_ holds the opinion that in the present stage of the study of animal life,[36] facts are much more desirable than theories. Experiment and observation must go on for many years before generalizations will be worth the making. Putting this belief into practice, he has bred and reared a large number of animals, making most careful notes on their physical and mental development, and furnishes in his book, resulting from these studies, a contribution of unquestionable value to comparative psychology.
