"Some forms of Kantianism put great weight on “what we can imagine” holding that this can be a source of insight into necessary connections. Thus various of Kant’s arguments about space and time depend on the purported fact that it is impossible for us to imagine certain things: we can know, Kant claims, a priori that space has only three dimensions because we cannot imagine it as having more than three dimensions. History in the form of non-Euclidean geometry and modern physics has put paid to that particular line of argument, but in general we should beware of depending too much on “What we can imagine?,” especially in politics. As Nietzsche puts it somewhere, sometimes the fact that you can’t imagine a situation in which things are very different from the way they are now is not an especially good argument for the claim that they must be as they now are, but, rather, represents a failure of your powers about which you should feel mildly apologetic."

“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 to accept the offer.”

“Humans in modern societies are driven by a perhaps desperate hope that they might find some way of mobilizing their theoretical and empirical knowledge and their evaluative systems so as both to locate themselves and their projects in some larger imaginative structure that makes sense to them. … Furthermore, many modern agents would like it to be the case that the form of orientation which their life has is, if not true, at least compatible with the best available knowledge.”

“The point of one of main constructions—the introduction of the “veil of ignorance”—is precisely to exclude from consideration empirical information that might prejudice the overriding normative force of the outcome. It is, then, extremely striking, not to say astounding, to the lay reader that the complex theoretical apparatus of Theory of Justice, operating through over 500 pages of densely argued text, eventuates in a constitutional structure that is a virtual replica of the arrangements that exist in the United States.”

“If the basic assumption of the theory of ideology is at all tenable, namely, that the general power relations embodied in our social structures can exert a distorting influence on the formation of our beliefs and preferences without our being aware of it, then we are definitely not going to put that kind of influence out of action by asking the agents in the society to imagine that they didn’t know their position. To think otherwise is to believe in magic: imagine you are “impartial” and you will be. In fact, doing that will be more likely to reinforce the power of these entrenched prejudices because it will explicitly present them as universal, warranted by reason, etc.”

“To the extent to which the pull that moves me really is irresistible, like an invincibly strong addiction, the normal procedures of evaluation, deliberation, choice, decision, etc. that constitute the substance of our political life are not operating. The same is true of overwhelming aversion. The person being tortured who simply wants it to stop, period, is also not a good model for an agent acting politically.”

“The notion of being an “enlightened” person does not reduce simply to that of being a person who has highly developed cognitive abilities or disposes of a vast stock of knowledge; neither does it reduce to the idea of being a morally good or socially useful person. “Enlightenment” is not a value-free concept because it is connected with some idea of devoting persistent, focused attention to that which is genuinely important in human life, rather than to marginal or subsidiary phenomena, to drawing the “correct” conclusions from attending to these important features—whatever they are—and to embodying these conclusions concretely in one’s general way of living. It involves a certain amount of sheer knowledge, an ability to concentrate and reflect, inventiveness in restructuring one’s psychic, personal, and social habits; but to be enlightened is not to “have” any bit of doctrine, but to have been structured in a certain way.”
