Pragmatic ethics

Similarly, ethical pragmatists think that norms, principles, and moral criteria are likely to be improved as a result of inquiry.

[1] 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.

[11] While some ethical pragmatists may have avoided the distinction between normative and descriptive truth, the theory of pragmatic ethics itself does not conflate them any more than science conflates truth about its subject matter with current opinion about it; in pragmatic ethics as in science, "truth emerges from the self-correction of error through a sufficiently long process of inquiry".

[2] A normative criterion that many pragmatists emphasize is the degree to which the process of social learning is deliberatively democratic:[12] "while deontologists focus on moral duties and obligations and utilitarians on the greatest happiness of the greatest number, pragmatists concentrate on coexistence and cooperation".

[16][17] Dean theorized that humans take diverse approaches to morality, and such polymorphism gives humanity resilience against a wider range of situations and environments, which makes moral diversity a natural consequence of frequency-dependent selection.

Pragmatic ethics was discussed by John Dewey (pictured at the University of Chicago in 1902, before his major works on pragmatic ethics were published).
