Abstract

This chapter concerns Hume's account in Book I of the Treatise of Human Nature (1739) of the operation of ‘general rules’. It considers their relation to conceptions of regularity, probability, circumstance, and experience that obtained in early modern logic and natural philosophy, taking occasion to reflect upon the significance of Hume's claim, in the Enquiry Concerning Human Understanding, that natural philosophy and moral philosophy are ‘derived from the same principles’. It concludes by suggesting that a number of Hume's essays are structured as reflections and refinements upon commonly-held general rules.
