 If faith is understood as commitment beyond independent inter-subjective evidential support to the truth of some overall interpretation of experience and reality, then all who commit themselves (with sufficient steadfastness) to such a Weltanschauung or worldview will be people of faith. Faith of this kind may be religious, and it may be religious without being theistic, of course, as in classical Buddhism or Taoism. Some have argued that faith is a human universal: Cantwell Smith, for example, describes it as ‘a planetary human characteristic [involving the] capacity to perceive, to symbolize, and live loyally and richly in terms of, a transcendent dimension to [human] life’ (1979, 140–141). There may also, arguably, be non-religious faith: for example, ‘scientific atheists’ or ‘naturalists’ may be making a faith-venture when they take there to be no more to reality than is in principle discoverable by the natural sciences. The suggestion that atheism rests on a faith-venture will, however, be resisted by those who maintain ‘the presumption of atheism’ (Flew, 1976): if atheism is rationally the default position, then adopting it requires no venture.
