Both the sociological as well as biblical-theological concepts of secularism may make use of the phenomenological discussions of implicit horizonal knowledge as informing explicit forms of knowing. If secularism may mean the erosion of faith by way of appropriation of fundamental beliefs about oneself or the world, the deep secularism may mean an appropriation of beliefs which make faith itself appear reprehensible. But perhaps the deepest form of secularism is the existence of scientific, reductionist naturalism; this may take the forms (...) eliminativism or of identity theory. This ‘secularism’ is such that it makes knowing itself impossible. Its basic move is to reduce the transcendental conditions of the manifestation, description, or display of the world to physical causes. Its most startling thesis is that first-person experience itself is an illusion and this illusion is the source of the major lies and beliefs that are most harmful for the culture, e.g. religious faith and belief in immortality. Unfortunately for deep secularism, as scientistic reductionistic materialist naturalism, it self-destructs. (shrink)
