We do not wish to “judge” or assess out surrounding merely as a kind of expressive activity carelessly projected onto the world, but we wish to evalu… - Raymond Geuss

One way … in which a political philosophy can be ideological is by presenting a relatively marginal issue as if it were central and essential.

It is an assumption that there is always one single dimension for assessing persons and their actions that has canonical priority. This is the dimension of moral evaluation; “good/evil” is supposed always to trump any other form of evaluation, but that is an assumption, probably the result of the long history of the Christianisation and then gradual de-Christianisation of Europe, which one need not make. Evaluation need not mean moral evaluation, but might include assessments of efficiency, … simplicity, perspicuousness, aesthetic appeal, and so on.

In its origin, liberalism had no ambition to be universal either in the sense of claiming to be valid for everyone and every human society or in the sense of purporting to give an answer to all the important questions of human life. … The ideal of liberalism is a practically engaged political philosophy that is both epistemically and morally highly abstemious. That is, at best, a very difficult and possibly a completely hopeless project. It is therefore not surprising that liberals succumb again and again to the temptation to go beyond the limits they would ideally like to set for themselves and try to make of liberalism a complete philosophy of life. … In the middle of the twentieth century, Kantianism presented itself as a “philosophical foundation” for a version of liberalism, and liberals at that time were sufficiently weak and self-deceived (or strong and opportunistic) to accept the offer.
