Progressive rationalism is the humanistic belief that improvements in global well-being depend on political change based on reason. It is progressive in the sense that could be falsified. It is a rationalist system of beliefs laden to empiricism, built, at least in first term, on certainties (reality is the one that once we stop to believe in it, doesn't disappear) not in mere beliefs. Progressive rationalists see corruption and faith as the two barriers to improved conditions. Politically it is opposed not only to right-wing systems of authoritarian or theocratic rule, but also to moral relativism exhibited by the left. It is distinct from both of its two stand-alone constituents by stating that both progressivism and rationalism are indispensable enablers for a flourishing society.
