The question of individualism was widely discussed in the 1960s. I suggest some of you read Joseph Agassi's article on methodological individualism which appeared in the 1960 British Journal of Sociology pp241-70 (available on JSTOR) and his follow up in the 1975 volume with an article titled Institutional Individualism, pp. 144-55. An if you are adventurous you can read chapter 2 in my 1982 and 2003 books. Lawrence Boland
