A quotation from W.T. Jones’ book, History of Western Philosophy: The Medieval Mind, (New York, Harcourt, Brace, and World, 1952), pp. 55-56:
Movements tend to be radical and extreme. As they are institutionalized, they become conservative and resist the very excitement and ferment that gave them birth. This is almost inevitable. An institution constitutes a lot of [people]; rules are needed to reduce the number of separate decisions that are made and so to minimize the changes of contradictory policies being initiated in different parts of the organization. But the rules are perforce designed for the general case, and since all actual cases are particular, the rule never exactly fits.
