Description of the project

PCE grant awarded by the CNCS, 2012-2015 ( PN-II-ID-PCE-2011-3-0719)

This is a 3-years research grant awarded by the Romanian national agency for scientific research (CNCS) to a team of 7 researchers and students coordinated by Dana Jalobeanu at CELFIS (Center for Logic, History and Philosophy of Science, Faculty of Philosophy, University of Bucharest) for a project aiming to explore the ways in which observation and experiment featured in various forms of natural history of the sixteenth and seventeenth centuries, in view of reassessing the role and function played by natural historical explorations (ranging from cosmography to medical natural histories and from diverse collections of ‘individuals’ to topical investigations of natural phenomena) in the development of experimental philosophy and ultimately of the early modern science.

The project aims, on the one hand, to disentangle the discussion on the nature and function of early modern experimentation from its age-long association with questions of testimony, credibility and evidence. Without questioning the role of experimentation in the assessment of scientific theories, we intend to show on particular cases that experiments have played an equally essential role in the context of (scientific) discovery: as problem-solving devices, tools for triggering creative analogies or devices for generating or ordering works of natural history.

On the other hand, our purpose is to reconstruct a series of particular case studies and discuss them comparatively in order to show how rich and how relatively unexplored is the field of what has been labeled as ‘natural history.’ We also aim to extend the field and the label ‘natural history’ into relatively unexplored writings that defy disciplinary boundaries. Works classified as cosmographies, geographies, travel literature, medical literature, spiritual medicine etc. will be the subject of our investigation, in so far that they can be shown to contain interesting and sophisticated observations and ingenious experiments. Last but not least we aim to trace the ways in which some of these observations and experiments ‘migrated’ from works of natural history into treatises of natural (and experimental) philosophy or ‘early modern science.’

A Cartesian challenge to the early modern philosophy of experiment

Much has been written about seventeenth-century experiments and experimental philosophy. My paper for the CELFIS seminar of October 8 aimed at engaging with that tradition. In particular, I was concerned with the recent discussion by Peter Anstey of the so called BBH model of the experimental philosophy (BBH stands for the name of Bacon, Boyle, and Hooke). As a reaction to Thomas Kuhn and Peter Dear, Peter Anstey’s article provides a very nice introduction into the Baconian experimentation and its main developments in the second half of the seventeenth century. Both Boyle and Hooke engage with a form of experimentation that is labelled here “Baconian.” It is not, however, the purpose of this small blog post to engage with the details of Anstey’s article, but rather to try to complement his analysis with a new example of experimentalism that can be found in a completely different source. This is the case of the experimental work of the Cartesian natural philosopher, Jacques Rohault.

In my lecture, I’ve referred to two experiments that were performed by Rohault: with pneumatic devices, on the one hand, and with glass drops, on the other hand. It is well known that Boyle was the main contributor to the pneumatic or baroscopic experiments of the 1660s. Hooke was among the first to examine glass drops and to provide an explanation for both the production of the small glass objects and for the curious phenomena produced by those. Interestingly, Rohault deals with both of these issues in experimental terms.

Now, one might very well wonder why is important that a Cartesian philosopher was providing an explanation for some intriguing experiments; after all, he is a Cartesian, therefore a speculative philosopher (see the Otago blog here and here), and he would explain all phenomena according to the principles of Cartesian physics. Yet, this classification of seventeenth-century philosophers into “experimental” and “speculative” should not be an impediment in searching for explanations in one’s writings. But there is more than that and I argued in my paper that it is precisely Rohault’s experimental approach to the study of the two phenomena that would make difficult to draw a clear boundary between his work and the works of the most representative experimenters of the BBH model.

I have argued elsewhere that Rohault treats the study of the properties of the air in experimental terms. He does not simply jump from the conclusions derived in the general part of Cartesian physics (which is most often claimed that he does), but actively engage in experiments and observations.

With respect to the study of glass drops, Rohault is also concerned to perform all the needed observations before providing an explanation. This is also what Hooke did in his Micrographia.

As a tentative conclusion for this very sketchy blog-post, I claim that based on these two experiments, Rohault should be placed in the same context with Boyle and Hooke, so as a representative of the BBH model. If, on the contrary, one would like to point to his “Cartesianism,” then, one simply overlooks his experiments and this would raise new worries for the use of historical categories: if one dismisses some experimental practices only on the basis of placing the practitioner to one or another camp, then, the problem is not any more with the use of experiment in natural philosophy, but with the way various natural philosophies of the period were classified in our histories.

Francis Bacon on the acceleration of time

This is a discussion of the notion of acceleration of time in different natural processes, as occurring in Francis Bacon’s Sylva Sylvarum, Century IV, experiments [301-354].

Keywords: acceleration of time: of liquors, of putrefaction, of growth, of stature, vivification, spirits.

Among the inter magnalia naturae which Bacon discusses in his works, the acceleration of time is one of the most important, for Bacon places it next to the creation of matter in divine miracles (introduction to century IV). The Verulam presents a twofold motivation for pursuing the acceleration of time in nature: “it is a spur to nature” and “of good use”. From the first observation one can infer that Bacon seems to do nothing than to present a process which takes place inside the boundaries of nature and which normally would develop in a larger period of time. Here is a presentation of some of Bacon’s most important examples of acceleration of time: acceleration of liquor’s clarification, of maturation, of putrefaction, of birth and of growth and stature.

1. Acceleration of liquors’ clarification.

Bacon talks about different types of accelerations and starts with discussing at some length the acceleration of liquors’ clarification. Here is, in a word, the strategy for achieving this task: “to know the means of accelerating clarification, we must first know the causes of clarification” [301]. And among the causes listed, the first one can be called mechanical (weight, motion, activity, percolation, etc): the separation between grosser and finer parts of the liquor; the second cause is the settlement of equal equilibrium between tangible and pneumatic and the third cause is the refining of the spirit itself.

After Bacon lists the causes, he moves to proposing some trails, which can be classified under three categories of experiments, as follows:

▪ instances of separation: [305], [307], [308], – percolation [311]

▪ instances of equilibrium: [309], [310]

▪ instances of the refining of the spirit [306], [309], [310]


2. Acceleration of maturation [312].

Bacon talks of several types of accelerations of maturation: of drinks, fruits, impostures and ulcers, metals; he also mentions that the one on “impostures and ulcers” will be tackled throughout the section “experiments medicinal”, but this has never appeared among Sylva’s entries.

a) maturation of drinks takes place by the congregation of spirits together and so it looks similar with clarification of liquors: “is effected partly by the same means that clarification is…” [312]. Examples of maturation of drinks are seen in must, wine and vinegar [313]. It is worth to note here that Bacon is plain here that spirits are endowed with motions, as the following examples suggest: “enforcing the motion of the spirit” [314]… “enforce the spirits by some mixtures” [314]. As in general for Bacon, the spirit seems to be here a more fundamental concept as motion. The question that opens up is what is the relationship between spirit and motion and the readers of this post are invited to express their opinion on this issue, too.

b) maturation of fruits is done by “calling forth of the spirits of the body outward…”, by digestion of the grosser parts – by heat, motion, attraction, putrefaction. Putrefaction therefore starts with maturation [317].

During his talk of maturation, Bacon also makes an interesting remark on the possibility to perform transmutations on bodies: “But we, when we shall come to handle the version and transmutation of bodies, and the experiments concerning metals and minerals, will lay open the true ways and passages of nature, which may lead to this great effect” [326]. One important question to ask here is: are those transmutations done within the boundaries of nature or not? Later on in the same entry, Bacon seems to be saying yes to the first option and contrasts it with the alchemist interpretation: “The sixth is, that you give time enough for the work; not to prolong hopes (as the alchemists do), but indeed to give nature a convenient space to work in”.


3. (Inducing and) Acceleration of putrefaction.

Putrefaction precedes generation, both being taken as the true boundaries of nature “or the guides to life and death” (introduction before [329]). Putrefaction is defined as being caused by a motion “confused and inordinate”, while on the contrary, vivification appears when the motion “has a certain order” [344].


4. Experiment solitary touching the acceleration of birth.

Bacon gives here two causes for the acceleration of birth: the rapid development of the embryo and the expulsion of it from the mother [353]. He altogether rejects the old thesis that this acceleration might suffer decisively from astral influences.


5. Experiment solitary touching the accelerating of growth and stature (of children) [354]

Bacon lists here three causes for speeding up growth and stature.

  1. Plenty of nourishment
  2. Nature of nourishment
  3. Exciting natural heat

The first one is not always recommended for it can be hurtful for the child. The second warns us not to feed the children with over-dry nourishment for this impedes growth. And finally, cold nourishment should be avoided in childhood for generally “heat [and not cold] is requisite for growth”, though a mature man should be more open to cold for it helps with condensing and preserving the spirit.




Vegetable Philosophy – Three Different Stages in the Mid-Seventeenth Century Hartlib Circle

According to the Hartlib Circle members’ interest for vegetable philosophy, I have been able to identify three different approaches associated with three different stages.

The first stage (the period until 1650) is dominated by the figure of Gabriel Plattes. [1] He is the first member of the Hartlib Circle expressing his vision upon vegetable philosophy and husbandry regarded as projects of ameliorating the material of Creation (soil, plants, human beings). Inspired from Bacon’s natural philosophy and sharing the general ideas animating the Circle, he considers amelioration a process of experimentation and technological improvement of the material of Creation. Plattes reformulates the view on husbandry, promoting a new type of ‘integrated science’ able to cultivate the land and the human soul as well. Apart from other tracts on husbandry published before,[2] Plattes used the alchemical tradition but committed the application of chemistry to a moral end. He developed his own experimental view on vegetable philosophy, placing at the very core of amelioration the idea of technological advancement (a project based on transmutation experiments and cyclical chemical change). Plattes’ contribution rests in providing a number of ‘technologies of amelioration’ for the material of Creation (soil, plants, human beings), technologies of salvation compatible with both economic advancement and religious salvation.

The second stage (1650-1660) is influenced in a great deal by the figure of Gabriel Plattes. All the writers on vegetable philosophy and husbandry (Austen, Blith, Dymock, Child, Beale, Weston and, later, Evelyn)[3] mention Plattes in their works and his contribution to the field. Writers of this stage express strong millenaristic beliefs due to their association with the Hartlib Circle and Samuel Hartlib. They continue the line imposed by Plattes, of technological experimentation and amelioration of the material of Creation but add grafting experiments. In this stage we can spot a shift of attention from alchemical transmutation to gardening, from experiments with minerals and metals to experiments with plants. The Virgilian influence is evident in this stage. We can include in this stage a part of Evelyn’s activity, the one chronologically associated with the Civil War. Due to his aristocratic affiliation, Evelyn experienced social isolation and he imagined different hortulan societies, living in perfect harmony with nature, sharing interest for the study of nature and for exploring the practical and spiritual possibilities of vegetable philosophy.

The third stage (the period after 1660), associated with the beginning of the Royal Society is characterized by amelioration accents only in a small deal.[4] If Evelyn’s Elysium Britanicum (started in the late 1650s) begins with his personal interpretations of the Genesis, the accent embedded in his 1660 works (such as Sylva and Pomona) is more scientific than religious. Austen, for instance, republished his treatise of Fruit-Trees and rededicated it to Royal Society Fellow Robert Boyle (see Austen Treatise, 3rd edition Oxford, 1665; Treatise of Fruit Trees, with the Spiritual Use of and Orchard (1653 – first edition). The first edition had been dedicated to Samuel Hartlib. The Royal Society revealed the so called closely guarded secrets and the spiritual reformed, so much embraced by Hartlib, was downplayed. [5]

[2] Such as Sir Hugh Plat’s Jewell House of Art and Nature, London, 1594. Although he had a deep interest in chemistry, medical chemistry and ways to improve the barren soil, Sir Hugh Plat was more influenced by the alchemical tradition (Paracelsus, John Hester, Bernard Palissy) than the desire to ameliorate the human estate.

Naturalism: Cardano, Telesio, and Bacon


Some notes on the reading group Naturalism: Cardano, Telesio, and Bacon (Bucharest-Princeton Seminar in Early Modern Philosophy, Bran 8-13 July 2014).


Proponents: Daniel Garber, Mihnea Dobre, Doina-Cristina Rusu.

The reading group examined some of the views of Girolamo Cardano, Bernardino Telesio, and Francis Bacon. We selected passages from Cardano’s De subtilitate (book II), Telesio’s On the nature of things (chaps. 8-16), and Bacon’s Sylva (experiments 30-32, 800-830) and the Novum Organum II. From the point of view of our research project, From Natural History to Science: the emergence of experimental philosophy, this was very important as it put in comparison Bacon’s views with some of his sources. We were especially interested in exploring the views of the three philosophers with respect to spirits, qualities, principles, and elements. We discussed the relation between heat, fire, and motion. Further, we compared the nature of air and the notion of “perception” in the three philosophers, asking how this would entail more experimental possibilities.

Our discussion was framed by the cosmological views of Cardano and Telesio. In Cardano, we were interested in his tripartite division of the elements (earth, air, and water) and what would be the status of fire (seen as a quality) in this new cosmological image. Cardano’s investigation of fire and his attempt to provide new experimental techniques for studying it allowed us to raise one of the main questions of the Bucharest-Princeton Seminar; namely, what “naturalization” means? Is this a worthy concept to describe the various attempts of early modern philosophers to pursue a more systematic empirical investigation of nature?

With Telesio we turned to explore the nature of air as the intermediate medium between the sky and the earth. We addressed the problem of how heat and cold act in the world and cause all the phenomena, and we opened the question of subtlety in experimental context. This question was further addressed in the case of the passages selected from Francis Bacon. His use of the weather-glass for exploring the effects of air and heat was discussed in the selected passages. The issue of measurement and how to perform accurate observations with the instruments was singled out in our discussion.

New Publications

Just a quick update on some of our recent publications.

For anyone interested in reading Galileo’s Sidereus nuncius as a natural history, Dana Jalobeanu’s recent article can offer a very useful introduction. The article was published by the Revue Roumaine de Philosophie.

Mihnea Dobre published a book review of Gideon Manning’s edited volume Matter and Form in Early Modern Science and Philosophy. The review can be found in the British Journal form the History of Science.


In the mid-seventeenth century, the problem of vegetable philosophy was very much debated inside the Hartlib Circle. Samuel Hartlib, the center of a wide circle of correspondents, acted as a publicizer, sharing, printing, and even budgeting a significant number of interesting and novel ideas, and in this way helping the wider dissemination of inventions and ideas. In 1650 Hartlib turned his attention from ecclesiastical and pedagogical projects to husbandry and vegetable philosophy.

What exactly is vegetable philosophy? And what is its relation with the tradition of husbandry? This field of study does not have a place in today’s classification of knowledge. It is not botanic, because its objectives are diverse (metals, stones, natural ores). It is not just agriculture, because it has a manifested inclination for alchemical experiments. And, to complicate things even further, it is not simply natural philosophy, because it has a practical and operative side, concerned with technological advancement and amelioration.

Vegetable philosophy emerged inside the Hartlib Circle and has been used to define a new field of interest, which could connect alchemical interests, extraction of metals, natural magic, cultivation of the land, the Baconian tradition of experimentation and dedication to the open character of knowledge and benefit of mankind. Vegetable philosophy is essentially technological and anti-speculative, experimental and operational, orientated towards production of specific results, recipes, and technologies transferable form one situation to another and even from one domain to another.

The concept of vegetable philosophy has been first used by Ralph Austen:

‘The Learned, and incomparable Author Sr Francis Bacon hath left unto men such Rules, and helps in all kinds of Learning, that they will be much wanting to themselves, if Arts, and Sciences improve not, very much above what they have been in former ages: And as the foresaid worthy Author was eminently seen in all Arts and Sciences, so his delight was especially (as is recorded of him) in Vegetable Philosophy, which was as it were, his darling delight, having left unto us much upon Record in his Naturall History; some part whereof referring to Fruit-trees, Fruits, and Flowers, I have, (by encouragement from himself) endeavoured to improve unto publique profit, according to what understanding, and experience I have therein … And seeing I perceive (since you have been pleased to honour me with your acquaintance) that your Genius is towards things in nature, to promote them, in order to the Common good, and that I have encouragements in my labours thereabout, (both as to the Theory and Practise) I humbly, present these following Observations into your hands, and am (for all your favours).’[1]

Which is the relation between husbandry and vegetable philosophy? Is vegetable philosophy just a sub-domain of husbandry (along with other sub-domains such as botanic, agriculture, metallurgy)? Or knowledge of husbandry is a prerequisite for vegetable philosophy?
