As a social critic, T.S. Eliot could scarcely be accused of an excess of relativism. Here, his assertion of what is ‘always desirable’ is, of course, part of his coolly mandarin tone, and that tone is the natural vehicle for the assumption that there is a class, largely selected by birth, destined to control the political affairs of a country, an assumption clearly intended as a calculated provocation in the Britain of the 1945 Labour government. The passage is, in these respects, characteristic of the later Eliot's persistent attempt, in the face of disagreeable social change, to appear to be taking the assumptions of the day before yesterday for granted. But as the sequence ‘education’, ‘instruction’ and ‘study’ suggests, one assumption which Eliot could indeed take for granted was that, in referring to ‘the history of political theory’, he was referring to something that was by this date an acknowledged part of an established academic practice. It was, as we shall see, part of his conservatism to presume that the larger academic practice in question was ‘the study of history’, yet even in this detail the passage offers a usefully concise, if somewhat oblique, indication of the themes of this ‘Postscript’.
