The manuscript notes described and trascribed below are unique: they show Bacon in the very act of originating, selecting and developing materials for the natural-philosophical projects of the crucial last years of his life. Many of the notes are drafts of material later incorporated in published texts—notably the Sylva Sylvarum . Examination of the drafts indicates that the Sylva is not a hotch-potch of plagiarized scraps. Bacon took great pains, acknowledged borrowings and drew heavily on his own extensive experimental and (...) observational work. The drafts also show that much of the material was used to display the explanatory power of his ambitious speculative philosophy. Preoccupation with the speculative philosophy is also evidenced in the notes which have no counterpart in the published works. Among these notes is a passage on the size of the universe, the motion of the fixed stars and the hypothesis of the earth's diurnal rotation. In that passage Bacon struggled with threats to his unswervingly geostatic conception of the universe. (shrink)

Francis Bacon's reflections on atomism have generally been misunderstood because they have never been systematically studied in relation to the speculative chemical philosophy which he developed in the interval between about 1592 and his death in 1626. This philosophy, in many respects unknown to historians until quite recently, was the only body of positive science which Bacon ever accepted. The speculative philosophy was, on the whole, chemical and non-mechanical, and consequently not consistent with atomist doctrines. In fact, Bacon never at (...) any time accepted the principal atomist tenets. It is therefore necessary to explain why he was interested in atomism at all. Of the several reasons for his interest one is especially important—namely, his belief that the speculative and atomic philosophies had affinities. In particular, he believed that of all the ancient philosophies atomism alone approached the ideals associated with the key notion of ‘subtlety’—ideals represented in their highest form in the speculative philosophy.

Francis Bacon (1561-1626) was a genuine midwife of modernity. He was one of the first thinkers to visualise a future which would be guided by a cooperative science-based vision of bettering human welfare. In this the first critical edition of his greatest philosophical work since the nineteenth-century, we find facing-page Latin translations and a thorough and detailed Introduction to the text.
