There is one other "peculiarity" of this volume which deserves comment.  In recent decades many American sociologists have come to equate theory building with the use of purely deductive logic.  This is a serious error since successful theory building requires both inductive and deductive logic.  To limit oneself to pure deductive reasoning in a field such as sociology is impossible, at least if one desires to be relevant; to attempt it and to claim it is only to deceive oneself and others and to inhibit the normal development of theory (1966, p. 21).
