The idea that nature is governed by laws and that the goal of science is to discover and formulate these laws, rose to prominence during the Scientific Revolution of the seventeenth century. It was manifestly held by the most significant actors of that revolution such as Galileo, Descartes, Kepler, Boyle, and Newton. But this idea was not new. In fact, it made an appearance in the Middle Ages, and it is likely to have emerged already in Antiquity.1In this paper we (...) pay close attention to the concept of law of nature in the writings of Roger Bacon, the outspoken Franciscan who promoted experimental science. We will be using Bacon as a test case to show that long before the... (shrink)

ABSTRACTThe paper examines the relevance of the nomological view of nature to three discussions of tide in the thirteenth century. A nomological conception of nature assumes that the basic explanatory units of natural phenomena are universally binding rules stated in quantitative terms. Robert Grosseteste introduced an account of the tide based on the mechanism of rarefaction and condensation, stimulated by the Moon's rays and their angle of incidence. He considered the Moon's action over the sea an example of the general (...) efficient causality exerted through the universal activity of light or species. Albert the Great posited a plurality of causes which cannot be reduced to a single cause. The connaturality of the Moon and the water is the only principle of explanation which he considered universal. Connaturality, however, renders neither formulation nor quantification possible. While Albert stressed the variety of causes of the tide, Roger Bacon emphasized regularity and reduced the various causes producing tides into forces. He replaced the terminology of ‘natures’ by one of ‘forces’. Force, which in principle can be accurately described and measured, thus becomes a commensurable aspect of a diverse cosmos. When they reasoned why waters return to their place after the tide, Grosseteste argued that waters return in order to prevent a vacuum, Albert claimed that waters ‘follow their own nature’, while Bacon held that the ‘proper force’ of the water prevails over the distant force of the first heaven. I exhibit, for the thirteenth century, moments of the move away from the Aristotelian concerns. The basic elements of these concerns were essences and natures which reflect specific phenomena and did not allow for an image of nature as a unified system. In the new perspective of the thirteenth century the key was a causal link between the position of the Moon and the tide cycle, a link which is universal and still qualitative, yet expressed as susceptible to quantification.

Of the many Schoolmen who read the pseudo-Aristotelian Secretum secretorum in the thirteenth century, none was more enthusiastic about this book than Roger Bacon. So highly did Bacon regard the Secretum that he prepared a redaction of the text, annotated it, and wrote an accompanying introductory treatise. Historians have long recognized the importance of Bacon's confrontation with the Secretum, but they have also misunderstood it. They have wrongly divided up Bacon's Secretum project between two widely separated dates. They have left (...) unasked the capital question of why Bacon undertook this project. More generally, they have fundamentally misjudged the place of the Secretum in Bacon's intellectual biography. Consequently, there are several distortions and gaps in the picture of Bacon's career currently circulating that deserve our critical attention. (shrink)

The change of medieval philosophy, known to have taken place in the 14th century, is accompanied by a new and extensive application of terminist logic and by a growing importance of the university of Oxford. This essay asks the question whether this development can be explained as a development of a specific English tradition within medieval logic. In the first part of the paper it is briefly shown that a certain discontinuity can be observed in the most important continental intellectual (...) centers; the 'sociological' conditions which make possible such distinct local traditions within the general development of medieval scholasticism are considered shortly. The second and larger part of the paper is a census of the English contribution to logic before Ockham, ordered according to the various literary genres: Summulae, Syncategoremata/sophismata, Grammar, Commentaries on the Organon. This census tends to prove that terminist logic had a continuous tradition in Oxford, a fact which may account for the preponderance of Oxford logic in the early 14th century. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:IntroductionWhen I first came across Dieter Hattrup's analysis of the De reductione I noted that the professor from Paderborn was trying, step by step, to trace the authorship back to friars influenced by Roger Bacon – a reductio ad Baconem, if you will. Hattrup's argument that Roger Bacon was indirectly involved in the composition of the De reductione evoked the fleeting memory of a pop culture game created by (...) American college students in the 1990s called the "Six Degrees of Kevin Bacon," whereby the characters in any given film must be linked to a film with the Hollywood actor, Kevin Bacon, by comparing no more than six films. To mention the esteemed theologian in such a fleeting cultural context is not meant to trivialize his argument in any way; rather, the intent is to underscore, admittedly tongue in cheek, the intricacies of his argument against Bonaventurian authorship of the De reductione as outlined in the monograph Ekstatik der Geschichte: Die Entwicklung der christologischen Erkenntnistheorie Bonaventuras and the journal article, "Bonaventura zwischen Mystik und Mystifikation: Wer ist der Autor von De reductione?" While Hattrup hesitates to claim Bacon as the author of De reductione, he does develop a systematic study that eventually leads, step by step, association by association, back to Roger Bacon. This essay examines and disputes Hattrup's claim by analyzing the historical context of his argument, the chronology and sources in question, the theme of the fourfold light and scripture, and the relationship between the sciences and theology. The numerous questions raised will underscore the fragility of his argument. Subsequent essays will treat the contemporary theological implications as well as the literary-theological genre and academic occasion of Bonaventure's De reductione.Historical ContextBefore we examine Hattrup's argument against Bonaventure as the author of the De reductione, let us first evoke the historical situation he suggests as the possible origin of the text. In 1267, Bonaventure warns his Minorite confreres of the dangers inherent in the sciences in the Collations on the Ten Commandments, and then, once again in 1268 in the Collations on Gifts of the Holy Spirit. The brothers in Bacon's circle are concerned because they contend that the sciences must be cultivated and consequently compose the De reductione. Their intent is to demonstrate how the sciences are integral to theology, such that even natural philosophy contains the wisdom of God. Hattrup sees this text stemming from Bacon's circle as a conscious attempt to subvert Bonaventure's understanding of the relationship between faith and reason in favor of the sciences by utilizing some of the General Minister's own language as mirrored in the Journey of the Soul into God and Francis of Assisi's experience of God in the natural world. The resulting text of the De reductione, according to Hattrup, is an intentional mystification of Bonaventure's own mystical or ecstatic methodology.Hattrup suggests that the De reductione came to Bonaventure's attention in 1270, but he is preoccupied with affairs in the early 1270s and only returns later to address the dangers he recognizes in the De reductione in another collation series in May of 1273, the Collations on the Six Days, or Hexaëmeron. The General Minister warns of those who entered religious life as friends of the sciences, the "hospites scientiae." They must place limits on their efforts in these fields of inquiry and not promote them as essential to theological reflection, as posited by the De reductione, if they wish to remain faithful to the ascetical-mystical vision of the Minorite Order. Unable to finish the Hexaëmeron due to ecclesial obligations, Bonaventure died unexpectedly in July of 1274 at the Council of Lyon. The text of the De reductione, found among Bonaventure's other writings, was dutifully copied and included among the Seraphic Doctor's literary corpus since at first glance this kurze Denkschrift appears to be from the deceased General Minister.Hattrup readily admits that..

To this date Roger Bacon remains one of the controversial and colorful figures in the history of empirical science. This paper is an attempt to ascertain his views regarding the nature and function of empirical science and to compare his writings on this topic with those of the more famous Francis Bacon. The ground for comparison is the fact that both men have often been cast in the same role in the history of science; i.e., they have both been acclaimed (...) as the first in the western world to emphasize and bring out the importance of experimental method in the accumulation of knowledge. In this connection Francis, of the sixteenth century, has long been acknowledged as the father of the experimental method in preference to Roger, of the thirteenth century. In effect, therefore, this paper probes the relative merits of the claims for each thinker. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:I am delighted to have the opportunity to speak on a topic that is of interest to all of us, inasmuch as it pertains to our summer endeavor, Franciscan education. I will do so, however, from the perspective of Roger Bacon – the Doctor Mirabilis – a friar who held his Order's education system in contempt. His scathing attacks included equally strong words for the Augustinians, Carmelites and Dominicans, (...) whom he lumped together with the Franciscans and dismissed as the ordines puerorum. Although he was a Franciscan, let me assure you that Bacon did not intend the "order of young boys" to be an endearing description of his confreres – but more about this later.Bacon's sharpest attacks are found in his Compendium studii philosophiae, written around 1271-1272. For those of you who are not familiar with this English friar, let me sketch out his biography. In all seriousness, what we know of his provenance, education, and career is indeed sketchy. Depending on how we read selected autobiographical remarks, he was born around 1214 or 1220 and died around 1292. After studying in Oxford, he became one of the first masters to comment on Aristotle in the Faculty of Arts in Paris during the 1240s and subsequently returned to England. Whether it was there, or perhaps later in France that he entered the Minorite Order is uncertain, nevertheless we find him in the Franciscan habit in 1256 and living in Paris. It will be from the vantage point of Paris that Brother Bacon will argue for radical curricular reform and critique the prevailing mendicant educational system. Later, perhaps back in England after 1268, he continues his criticism until his death in 1292.As I begin, allow me a few moments to explain why I think Bacon's critique should not be ignored by Franciscans nor relegated to an obscure footnote by educators. To offer a critique of a position, belief, or view is something that is to be expected from those in colleges and universities who have been educated in what we call "critical thinking." However, as Michael Roth noted in The Chronicle of Higher Education, to critique is the beginning, not the end or goal of the process. His article, entitled "Beyond Critical Thinking," warns educators that many of our best students are considered intelligent because of their sharply-honed, acquired ability to take apart, unmask, or deconstruct the beliefs of others. Experts at exorcizing and banishing meaning from firmly held texts, they are likewise unable to find or construct meaning in their own lives from these sources which have inspired, formed, and challenged countless individuals through the centuries.Let me offer you an example from my own experience at Flagler College. I have taught everything from Introduction to the Old Testament to upper-level Contemporary Theological Thought. Over the years I have seen that taking a critical approach to the material is crucial, yet there is a corresponding need to assist students along the path toward wisdom through the integration of our academic critique within a coherent worldview. For any number of reasons it is an exhilarating, empowering, and I would say, even a liberating experience for some to learn that the Scriptures are problematic, and thereby open to various interpretations. This opens the door for some to challenge the authority their parents and pastors have wielded over them, while emboldening other students to challenge and even embarrass peers. For example, one of my students discovered that the King James Bible contained John 5:4 which many modern translations eliminated since scholars hold that it was something similar to a gloss. He subsequently challenged others by questioning how they could believe that God had an eternal claim on anyone when scholars were not even sure what parts of the Bible were legitimate, or even true. His proof text in these discussions.. (shrink)

did roger bacon and peter john olivi ever meet? We suggest a positive answer to this question. After he became a Franciscan in 1257, Roger Bacon spent ten years at the Franciscan Paris convent. In those years he wrote the De multiplicatione specierum —his most thought-out piece—the Opus majus, Opus minus, and Opus tertium, which he completed by early 1268. It is not clear whether Bacon returned to England after 1268, or remained in Paris until 1280.1 Peter John Olivi wrote (...) the Summa questions in several phases.2 According to Sylvain Piron's chronology, Olivi's questions on Physics should be dated before 1270, and his theory of...

IT IS CERTAINLY THE CASE that twelfth- and thirteenth-century treatises on logic represent in great part attempts to represent the Organon, Aristotle’s books on logic, by rearranging the material, adding clarifications, and sometimes breaking new ground as in the case of the treatise on the property of terms. Thus when Roger Bacon is writing his Summulae dialectices around 1252, he is confronted by the problem of what to do with the material on the classification of statements into single or multiple, (...) and simple or composed in chapter 5 of Aristotle’s On Interpretation. There, apropos of the two divisions and interspersed among other claims, we read the following. (shrink)
