Observations, experiments and inquiries into the world of plants figure prominently in Francis Bacon’s Sylva Sylvarum. My purpose in this article is to offer a survey of this very rich and relatively under-investigated natural historical material, with the purpose of showing two things. First, I show that these inquiries unveil a sophisticated instrumental approach. Bacon treats plants as chemical laboratories in which one can investigate the fundamental processes of nature and the continuous ‘pneumatisation’ of matter. A detailed examination of this (...) instrumental approach can shed important light upon Bacon’s reductionist strategies of explanation. Second, I show that some of the experiments with plants recorded in the Sylva Sylvarum uncover several layers of theoretical vocabulary. In this experimental context, key concepts of Bacon’s natural philosophy are further refined and acquire new meanings. (shrink)

Francis Bacon’s main contribution to the emergence of experimental philosophy was a new way of thinking about the serial character of experimental practices. His natural and experimental histories document his constant attempts to order experimental inquiries. They consist of large collections of lists and series of items, most of which are called “experiments.” For Bacon, “experiment” is a generic term; it is used for tests and trials, recipes, ideas of experimental investigations, theoretical observations and methodological suggestions. Experiments never stand alone (...) in a natural history; they come in series of numbered items, sometimes grouped under “heads” and “topics of inquiry.” In the Latin natural histories.. (shrink)

This article examines the philosophical implications underlying Bacon's views on historical knowledge, paying special attention to that variety of historical knowledge described by Bacon as “natural.” More specifically, this article explores the interplay of history and fable. In the sphere of thought, fabula is the equivalent to materia in nature. Both are described by Bacon as being “versatile” and “pliant.” In Bacon's system of knowledge, philosophy, as the domain of reason, starts from historiae and fabulae, once memory and the imagination (...) have fulfilled their cognitive tasks. This means that, for Bacon, there is no such thing as a pure use of reason. He advocates a kind of reason that, precisely because it is involved with matter's inner motions, is constitutively 'impure'. The article shows how the terms historia and fabula cover key semantic areas in defining Bacon's philosophy: historia may mean “history” as well as “story,” fabula “myth” as well “story.” In both cases, we can see significant oscillations from a stronger meaning to a weaker one, as if the power of nature decreases moving from histories and myths to stories. On the other hand, there are cases in which Bacon seems to stick to a diachronic view of the meaning of fables and histories, such that the transition from myths to history, especially natural history, is described as a collective effort towards reality and enlightenment.

This chapter examines how the problem of the nature of body had become the central debate in the field of natural philosophy in England by the middle of the seventeenth century. It explains that the nature of the physical body is one of the major problems of seventeenth-century natural philosophy and that it began, at least in part, as a byproduct of a change in the philosophical vocabulary. The chapter also evaluates solutions proposed to address the problem concerning the nature (...) of body, including those derived from theory of matter and mixed mathematics. (shrink)

The Historia densi et rari, published posthumously in 1658, is probably Francis Bacon’s most complex natural and experimental history. It contains observations and experimental reports, quantitative estimates and tables, and theoretical and methodological considerations, in a structure which has never been fully investigated. I provide here a fresh reading of this text from the perspective of scientific practices. I claim that Historia densi et rari represents a quantitative and instrumental investigation assembled with the help of Bacon’s philosophy of experiment as (...) developed in the Novum organum. I first discuss the role played in the Historia densi et rari by the various instances of special power in delineating the object of research. I then analyze the ways in which a special class of instances of special power, the “mathematical instances,” are used in the Historia densi et rari to make the inquiry both more precise, and more abstract. Bacon used mathematical instances to transform traditional recipes of pneumatics into quantitative, more general investigations into universal motions and processes. Finally, I discuss two examples of scientific practice at work: the attempt to use instruments to gradually define and clarify “proper” notions of “rarefaction” and “condensation,” and the redefinition of a metaphysical concept in instrumental and operational terms.

This book offers a comprehensive and unitary study of the philosophy of Francis Bacon, with special emphasis on the medical, ethical and political aspects of his thought. It presents an original interpretation focused on the material conditions of nature and human life. In particular, coverage in the book is organized around the unifying theme of Bacon’s notion of appetite, which is considered in its natural, ethical, medical and political meanings. The book redefines the notions of experience and experiment in Bacon’s (...) philosophy of nature, shows the important presence of Stoic themes in his work as well as provides an original discussion of the relationships between natural magic, prudence and political realism in his philosophy. Bringing together scholarly expertise from the history of philosophy, the history of science and the history of literature, this book presents readers with a rich and diverse contextualization of Bacon’s philosophy.

The early modern era produced the Scientific Revolution, which originated our present understanding of the natural world. Concurrently, philosophers established the conceptual foundations of modernity. This rich and comprehensive volume surveys and illuminates the numerous and complicated interconnections between philosophical and scientific thought as both were radically transformed from the late sixteenth to the mid-eighteenth century. The chapters explore reciprocal influences between philosophy and physics, astronomy, mathematics, medicine, and other disciplines, and show how thinkers responded to an immense range of (...) intellectual, material, and institutional influences. The volume offers a unique perspicuity, viewing the entire landscape of early modern philosophy and science, and also marks an epoch in contemporary scholarship, surveying recent contributions and suggesting future investigations for the next generation of scholars and students.

In this paper we argue that the primary issue in Descartes’ Principles of Philosophy, Part II, articles 1-40, is the problem of individuating bodies. We demonstrate that Descartes departs from the traditional quest for a principle of individuation, moving to a different strategy with the more modest aim of constructing bodies adequate to the needs of his cosmology. In doing this he meets with a series of difficulties, and this is precisely the challenge that Newton took up. We show that (...) Descartes’ questions and his strategy influenced not only Newton’s account of physical bodies, but also the structure of his mechanics. (shrink)
