‘*Of all our thinkers he is the one who, as it appears to me, has formed for 
himself the largest new scheme of a systematic philosophy, and, in relation to 
some of the greatest questions of philosophy in their most recent forms, as set or 
reset by the last speculations and revelations.of science, has already shot his 
thoughts the farthest.”—Prof. Davip Masson, in “* Recent British Philosophy.” 
‘‘His bold generalizations are always instructive, and some of them may in 
the end be established as the profoundest laws of the knowable universe.”—Dr. 
James McCosu, in the ‘* Intuitions of Mind.” 
**One who, whether for the extent of his positive knowledge, or for the pro- 
fandity of his speculative insight, has already achieved a name second to none in 
the whole range of English philosophy.’’— Westminster Review. 
‘* The work (‘ Descriptive Sociology *) is a gigantic one; its value, when com- 
plete, will be immeasurable; and its actual influence on the study of sociology, 
and help to that study, greater perhaps than any book yet published. It isa 
cyclopedia of Social Science, but a cyclopedia edited by the greatest of sociolo- 
gists.’"—G. W. SMALLEY.
