Much as it is appropriate for scientists to act as though a hypothesis were true despite expecting future inquiry to supplant it, ethical pragmatists acknowledge that it can be appropriate to practice a variety of other normative approaches (e.g.
consequentialism,
deontological ethics, and
virtue ethics), yet acknowledge the need for mechanisms that allow people to advance beyond such approaches, a freedom for discourse which does not take any such theory as assumed. Thus, aimed at
social innovation, the
practice of pragmatic ethics supplements the practice of other normative approaches with what
John Stuart Mill called "experiments in living". Pragmatic ethics also differs from other normative approaches
theoretically, according to
Hugh LaFollette: • It focuses on society, rather than on lone individuals, as the entity that achieves
morality. In Dewey's words, "all conduct is ... social". • It does not hold any known moral criteria as beyond potential for revision. Pragmatic ethics may be misunderstood as
relativist, as failing to be objective, but pragmatists object to this critique on grounds that the same could be said of science, yet
inductive and
hypothetico-deductive science is our
epistemological standard. Ethical pragmatists can maintain that their endeavor, like inquiry in science, is objective on the grounds that it converges towards something objective (a thesis called
Peircean realism named after
C. S. Peirce). • It allows that a moral judgment may be accepted in one age of a given society, even though it will cease to be accepted after that society
morally progresses (or may already be rejected in another society). The change in moral judgments about
slavery that led to the
abolition of slavery is an example of the improvement of moral judgments through moral inquiry and advocacy. LaFollette based his account of pragmatic ethics in the writings of
John Dewey, but he also found aspects of pragmatic ethics in the texts of
Aristotle,
John Stuart Mill, and
Martha Nussbaum. Barry Kroll, commenting on the pragmatic ethics of
Anthony Weston, noted that pragmatic ethics emphasizes the complexity of problems and the many different
values that may be involved in an ethical issue or situation, without suppressing the conflicts between such values. ==Criticisms==
