"Besides number and intensity, there is a technique of group activities which must be taken into account. Blows, bribes, allurements of one kind and another, and arguments also, are characteristic, and to these must be added organization. A group will differentiate under fitting circumstances a special set of activities for carrying on its work. We must learn how these specialized activities vary under different forms of group opposition, how the technique changes and evolve. We shall find that the change in methods is produced by the appearance of new group interests, directed against the use of the method that is suppressed. If violence gives way to bribery, or bribery to some form of demagogy, or that perhaps to a method called reasoning, it will be possible, if we pursue the study carefully enough, to find the group interest that has worked the change. That group will have its own technique, no more scrupulous probably than the technique it suppresses, but vigorously exerted through the governing institutions of the society, or possibly outside those institutions. Technique will of course vary with the intensity of interest, as for instance when assassination is adopted by revolutionists who can find no other method to make themselves felt against their opponents. Number also has intimate relations with both technique and intensity." (Arthur Bentley, 1908, pp. 216-217)
