Roger Scruton explains why the modern poet/critic must be essentially conservative:

For let us ask ourselves just what is required of “one who knows” [the poet/critic]. Should he, in the modern world, devote himself like Sartre or Foucault to undermining the “structures” of bourgeois society, to scoffing at manners and morals, and ruining the institutions upon which he depends for his exalted status? Should he play the part of a modern Socrates, questioning everything and affirming nothing? Should he go along with the mindless culture of play, the post-modernist fantasy world in which all is permitted since neither permission nor interdiction have any sense?

To answer yes to any of those questions is in effect to live by negation, to grant nothing to human life beyond the mockery of it. It is to inaugurate and endorse the new world of “transgression,” a world which will not reproduce itself, since it will undermine the very motive which causes a society to reproduce. The conservative response to modernity is to embrace it, but to embrace it critically, in full consciousness that human achievements are rare and precarious, that we have no God-given right to destroy our inheritance, but must always patiently submit to the voice of order and set an example of orderly living. The future of mankind, for the socialist, is simple: pull down the existing order, and allow the future to emerge. But it will not emerge, as we know. These philosophies of the “new world” are lies and delusions, products of a sentimentality which has veiled the facts of human nature.
