Pragmatic ethics
Ethical theory which postulates that societal progress can inform standards of moral behavior
Pragmatic ethics is a kind of ethics that focuses on the development in society: People such as John Dewey believe that the moral progress a society makes is related to the progress and level in science of that society. Scientists look at hypotheses and examine them; they can then act in such a way that they believe these hypotheses to be true. When science advances, future scientists can replace a hypothesis with a better one.
