There are certain primary religious beliefs which are basic to a whole religious Weltanschauung, for they are the cornerstone of the whole edifice. If these beliefs are unintelligible, incoherent, irrational or false the whole way-of-life, centering around them, is ‘a house of cards’. Certain segments of it may still be seen to have a value when viewed from some other perspective, but if these primary religious belief are faulted, the religious Weltanschauung itself has been undermined. If it has been undermined and if people recognise that it has been undermined and still go around believing in it, accepting and acting in accordance with its tenents, they are then being very irrational. And while in humility we should recognise that we all suffer from propensities to irrationality and perhaps in some spheres of our life can't help being irrational, it is a propensity we should resist, for to be irrational is to do something we ought not to do.
