“It would be unfair to deny to these essays very great ability. The style is clear and vigorous; the amount of thought and power displayed is considerable. Many of the remarks on our social condition, on the prevention of disease, on the forces which act on population, are exceedingly valuable, and may be read with much advantage.”—The Illustrated Review (London).


“The whole set of Essays is at once the profoundest and the kindliest that has for some time tried to set people a-thinking about themselves and their destiny.”—Daily Telegraph (London).


“Mr. Greg is fertile, vigorous, and suggestive in his thinking; he is a thoughtful, earnest, independent, and well-informed man, who really faces the problems he discusses.”—Boston Globe.


“Full of writing of singular force and singular candor.”—The Spectator (London).
