Reason the Fundamental Rule

There was a long-standing tradition in Christian thought that presented faith in the Church and in the Bible as reasonable.13 We should accept guidance if we have reason to believe that the guide knows and is truthful. Hence the fundamental rule of belief and action is reason, though in some situations reason may lead us to see that we should follow some other guide, which will then provide a “secondary” or “derivative” rule—once we have been convinced by reasons that some guide is reliable, it is rational to follow that guide.

This is the idea behind the opening chapter of the Philosophical Commentary: Reason or the “light of Nature” is a “Standard and original Rule” (p. 69), a “standing Test of all Precepts … not excepting even those which God has afterwards reveal’d in an extraordinary way” (p. 70). Adam thought himself obliged to obey God only “because that inward Light … continually presented the Idea of his Duty, and of his dependence on the Sovereign Being” (p. 70), so that for Adam “the reveal’d truth was sub-ordinate to the natural Light in him” (p. 70). A theologian would treat the Gospel as the first rule of morality, but “writing as a Philosopher, I’m obliged to go back to the original and mother Rule, to wit, Reason or natural light” (p. 80); the Gospel is “a second standing Rule collated with the Original” (p. 81). Similarly, for the Jews the law of Moses was a secondary rule recommended by reason: For the Mosaic Law, “once vouch’d by the natural Light, acquir’d the Quality of a Rule and Criterion, in the same manner, as a Proposition in Geometry once demonstrated from incontestable Principles, becomes it self a Principle with regard to other Propositions” (p. 72).

One of the major cultural changes in Europe since Bayle’s time is widespread loss of the conviction that there is any reliable secondary rule, so that even many Christians these days go back directly to reason in considering controversial questions of morality. But like Christian fundamentalists of today, Bayle believed that the Bible, though not the Church, is indeed a reliable secondary rule, and he looked for a way of reconciling the Bible with morality in cases of apparent conflict. He calls on the idea that God may dispense with his own laws in special cases to explain such passages as Numbers 25:7–11, where God might seem to have approved murder; see pp. 85, 248.
