There is no doubt, from all points of sociological, or psychological analysis, and in any question of theory, the manner and type of behaviour observed in the performance of an act is of the highest importance. Indeed behaviour is a fact, a relevant fact, and one that can be recorded. And foolish indeed and short-sighted would be the man [sic*] of science who would pass by a whole class of phenomena, ready to be garnered, and leave them to waste, even though he [sic] did not see at the moment to what theoretical use they might be put!
*I feel the sexist assumption encoded in “man of science” detracts from the quality of the quote.
