Clarke's statement of the ``Rule of Righteousness with respect to ourselves'' I pass over, because it is, as he states it, a derivative and subordinate rule. It is that we should preserve our being, be temperate, industrious, etc., with a view to the performance of Duty: which of course supposes Duty (i.e. the ultimate and absolute rules of Duty) already determined. I may observe that the reasonableness of Prudence or Self-love is only recognised by Clarke indirectly ; in a passage which I quoted before (p. 120).
