 Yet other Phenomenologists adopt a deontic viewpoint and challenge the axiological and constructivist approaches on the ground that values are often experienced as prescriptions, norms, imperatives, obligations, demands, and requirements. Since values are experienced in relation to feelings and emotions, the objection goes, it would seem that we are always free to value and choose otherwise, precisely because our feelings, interests, and choices can vary. Because of that, it is difficult to understand in what sense the values we encounter can be thought to impose unconditional obligations.
