Freedom of conscience and freedom of choice are not the same; where conscience dictates, choice decides. Where freedom of conscience is at stake, the relevant right is to perform a duty, not to make a choice. This was the issue for Madison and Jefferson. Religious liberty addressed the problem of encumbered selves, claimed by duties they cannot renounce, even in the face of civil obligations that may conflict.

Despite their differences, both Hayek and Rawls reject the idea that economic rewards should reflect what people deserve. In doing so, they acknowledge that they are challenging conventional wisdom. The notion that justice means giving people what they deserve seems deeply embedded in untutored common opinion. Rawls notes the “tendency for common sense to suppose” that income and wealth should be distributed according to moral desert, and Hayek admits that his renunciation of merit “may appear at first so strange and even shocking” that he must “ask the reader to suspend judgment” until he can explain.
But even as free-market liberalism and welfare state liberalism set the terms of public discourse over the past half century, they did not dislodge the widely held conviction that what people earn should reflect what they deserve. To the contrary, during those decades, meritocratic attitudes toward success tightened their hold, even as mobility stalled and inequality deepened.

It is sometimes thought that liberal principles can be justified by a simple version of moral relativism. Government should not "legislate morality," because all morality is merely subjective, a matter of personal preference not open to argument or rational debate. "Who is to say what is literature and what is filth? That is a value judgment, and whose values should decide?" Relativism usually appears less as a claim than as a question: "Who is to judge?" But the same question can be asked of the values that liberals defend. Toleration and freedom and fairness are values too, and they can hardly be defended by the claim that no vales can be defended. So it is a mistake to affirm liberal values by arguing that all values are merely subjective. The relativist defense of liberalism is no defense at all.
