Then again the dilettanti make light work of social questions. Everyone, by the fact of living in society, gathers some observations of social phenomena. The belief grows up, as it was expressed some time ago by a professor of mathematics, that everybody knows about the topics of sociology. Those topics have a broad and generous character. They lend themselves easily to generalizations. There are as yet no sharp tests formulated. Above all, and worst lack of all as yet, we have no competent criticism. Hence it is easy for the aspirant after culture to venture on this field without great danger of being brought to account, as he would be if he attempted geology, or physics, or biology. Even a scientific man of high attainments in some other science, in which he well understands what special care, skill, and training are required, will not hesitate to dogmatize about a topic of sociology. A group of half-educated men may be relied upon to attack a social question and to hammer it dead in a few minutes with a couple of commonplaces and a sweeping a priori assumption. Above all other topics, social topics lend themselves to the purposes of the diner-out.
Two facts, however, in regard to social phenomena need only be mentioned to be recognized as true. (1) Social phenomena always present themselves to us in very complex combinations, and (2) it is by no means easy to interpret the phenomena. The phenomena are often at three or four removes from their causes. Tradition, prejudice, fashion, habit, and other similar obstacles continually warp and deflect the social forces, and they constitute interferences whose magnitude is to be ascertained separately for each case. It is also impossible for us to set up a social experiment. To do that we should need to dispose of the time and liberty of a certain
