 Models of autonomy considered above include a condition that mirrors this constraint, in that a person is autonomous relative to some action-guiding norm or value only if, upon critical reflection of that value, she identifies with it, approves of it, or does not feel deeply alienated from it. Combining this view with the endorsement constraint, liberalism carries the implication that autonomy is respected only when guiding values or principles in a society can be embraced in some way by those governed by them. This will connect directly to the liberal theory of legitimacy to be discussed below.
