Pragmatism
Pragmatism is a straightforward practical way of thinking about things or dealing with problems, concerned with results rather than with theories and principles. It was created by American Progressives as a method which rejected philosophical principles.[1] Politicians are often described as pragmatic if they change their policies, or even their professed beliefs, based on what will produce results in a given political climate, or what will win them votes.
Pragmatism is also a philosophical school with origins in the United States which postulates that truth is whatever is useful and rejects foundationalism. Perhaps the most well-known pragmatist was William James, who wrote extensively on the subject of religious experience and was writer Henry James' brother. The late philosopher Richard Rorty is also remembered as a "neo-pragmatist". Hu Shi, a famed Chinese modern thinker who was prominent in the pre-Communist China was also influenced by American pragmatism.
Pragmatism is a form of nihilism since it rejects philosophical principles, it is also similar to moral relativism. Liberals often use pragmatism to advocate for laws based not on morals or principles but what is more practical as well as opposing Conservative ideas, for instance, President Ronald Reagan called for the war on drugs, which liberals oppose on the basis on what is practical rather than morals and principles. The opposite or pragmatism is idealism.
