Abstract
This paper revisits Bacon's persistent 'mechanical' imagery by which he described the 'aid' through which the human mind would be rendered adequate to framing axioms about nature's processes and properties that underlie all natural phenomena. It argues that the role Bacon ascribed to his own insights into the properties and motions of matter is crucial for grasping such instrumental imagery, because his own writings—both methodological and natural historical—need to be read as themselves comprising, at least in incipient form, the very instruments of which they speak. From that reflexive standpoint, this paper in particular focuses on the 'aid' to the senses that his natural histories were to have offered under the interpretative guidance offered by the Novum organum and other works. The 'hypothetical' status to which Bacon is often thought to have accorded his own natural philosophical insights does not adequately take into account the transformative power Bacon thought these insights should have through his own writings. The fact that Bacon was keenly sensitive to the psychological effects of textual authority in his intellectual milieu prompts new reflection concerning how he intended his own texts to be read, and how we should read them.
