Aristotle vs Francis Bacon

Francis Bacon's Novum Organum (1620) was a programmatic attack on the Aristotelian inheritance that had dominated scholastic natural philosophy for four centuries. The contrast between Aristotelian and Baconian method is the foundational episode of early modern philosophy of science.

Where they agree

Both held that systematic inquiry into nature is the proper task of philosophy, both rejected the appeal to mere authority and tradition in matters of natural knowledge, and both took the analysis of method as central. Bacon's framework for inquiry inherits as much from Aristotle as it rejects, and the rules of inductive collection in the Novum Organum presuppose Aristotelian categories.

Where they disagree

Aristotle's natural philosophy proceeds from clearly grasped first principles through the analysis of essences — what a thing is, by what cause, for what purpose. Bacon held that this method had collapsed under its own weight: the scholastic syllogism reproduced received error rather than uncovering new truth, and the search for final causes had displaced the experimental investigation of efficient causes. Bacon's Novum Organum proposes a method of disciplined induction by tables of presence and absence, the elimination of the idols of the mind, and the systematic interrogation of nature through experiment. Where Aristotle's natural philosophy aimed at understanding what things are, Bacon's aimed at gaining power over nature for the relief of the human estate.
