Is rational knowledge sufficient to guide all human actions? Many claim that religion is needed in addition to science. The strength of scientific or intellectual advice by experts has to be assessed. To accept religion as a guide has its own problems. Mythology cannot be objectively verified and there are so many of these. Religious practice has resulted in undesirable and sometimes extremely obnoxious actions. Can any role for religion be justified despite this? When does scientific advice degenerate to irrelevance? When does religious guidance become dogmatic and dangerous? The monograph tries to analyze these issues without being bogged down by the confusing details of advanced science or scholastic study of religions. Then, one can assess the ability of science and religion to guide ones own actions. The path for human action emerges as a walk along a fractal knife edge with science and religion as objective and subjective guides to human action.
