Bacon’s scientific method, in his own words, is ‘hard in practice but easy to explain’ (NO, Preface). Bacon proposes ‘to establish degrees of certainty’ (NO, Preface) by starting from ‘sense-perception’ (NO, Preface). He is determined to reject ‘ways of thinking that track along after sensation’ (NO, Preface). The aim is to be able to derive ‘notions’ and ‘axioms’ (NO, 1.18) and to acquire a ’more certain way of conducting intellectual operations’ (NO, 1.18). In the project of searching into and discovering the truth, Bacon proposes to ‘derive axioms from senses and particular events in a gradual and unbroken ascent’ (NO, 1.19).
