In the 13th century, the availability of Aristotle’s treatises of natural philosophy encouraged forms of integration between libri naturales and sapientia biblica. Instead of diving into allegory and symbolism, several Dominican exegetes began to explore more realistic approaches. The foremost figure is Albert the Great. In his biblical commentaries, philosophy of nature and theology join forces as complementary forms of knowledge. By focusing on Albert’s De vegetabilibus, this paper is aimed at analyzing in which ways the Dominican master reuses his (...) naturalistic and, especially, botanical knowledge as an exegetical tool to deepen both the historical and the allegorical sense, realism and spiritual interpretation.

The reception of the translations of Aristotelian and pseudo-Aristotelian works at the University of Paris in the thirteenth century promoted a new understanding of the sciences as specialized fields of knowledge. The huge amount of translations required a new organization of knowledge, which included novel subjects and categories. Among these there is a very special case, namely the pseudo-Aristotelian De plantis, translated from Arabic into Latin and then back into Greek to be re-translated into Latin again. De plantis was included (...) in the new curriculum in Ripoll 109, and constituted the main source for botanical studies until the sixteenth century. Throughout this paper we will explore the reception and impact of De plantis in both the Arabic and the Latin traditions. We aim to show its foundational role in the development of botany as a theoretical discipline within the natural sciences. (shrink)

Bio-ontologies are essential tools for accessing and analyzing the rapidly growing pool of plant genomic and phenomic data. Ontologies provide structured vocabularies to support consistent aggregation of data and a semantic framework for automated analyses and reasoning. They are a key component of the Semantic Web. This paper provides background on what bio-ontologies are, why they are relevant to botany, and the principles of ontology development. It includes an overview of ontologies and related resources that are relevant to plant (...) science, with a detailed description of the Plant Ontology (PO). We discuss the challenges of building an ontology that covers all green plants (Viridiplantae). Key results: Ontologies can advance plant science in four keys areas: 1. comparative genetics, genomics, phenomics, and development, 2. taxonomy and systematics, 3. semantic applications and 4. education. Conclusions: Bio-ontologies offer a flexible framework for comparative plant biology, based on common botanical understanding. As genomic and phenomic data become available for more species, we anticipate that the annotation of data with ontology terms will become less centralized, while at the same time, the need for cross-species queries will become more common, causing more researchers in plant science to turn to ontologies.

The Plant Ontology (PO; http://www.plantontology.org/) is a publicly-available, collaborative effort to develop and maintain a controlled, structured vocabulary (“ontology”) of terms to describe plant anatomy, morphology and the stages of plant development. The goals of the PO are to link (annotate) gene expression and phenotype data to plant structures and stages of plant development, using the data model adopted by the Gene Ontology. From its original design covering only rice, maize and Arabidopsis, the scope of the PO has been expanded (...) to include all green plants. The PO was the first multi-species anatomy ontology developed for the annotation of genes and phenotypes. Also, to our knowledge, it was one of the first biological ontologies that provides translations (via synonyms) in non-English languages such as Japanese and Spanish. There are about 2.2 million annotations linking PO terms to over 110,000 unique data objects representing genes or gene models, proteins, RNAs, germplasm and Quantitative Traits Loci (QTLs) from 22 plant species. In this paper, we focus on the plant anatomical entity branch of the PO, describing the organizing principles, resources available to users, and examples of how the PO is integrated into other plant genomics databases and web portals. We also provide two examples of comparative analyses, demonstrating how the ontology structure and PO-annotated data can be used to discover the patterns of expression of the LEAFY (LFY) and terpene synthase (TPS) gene homologs.

Pérez Carballo adopts an epistemic utility theory picture of epistemic norms where epistemic utility functions measure the value of degrees of belief, and rationality consists in maximizing expected epistemic utility. Within this framework he seeks to show that we can make sense of the intuitive idea that some true beliefs—say true beliefs about botany—are more valuable than other true beliefs—say true beliefs about the precise number of plants in North Dakota. To do so, however, Pérez Carballo argues that we (...) must think of the value of epistemic states as consisting in more than simply accuracy. This sheds light on which questions it is most epistemically valuable to pursue. (shrink)

This volume of twelve specially commissioned essays about species draws on the perspectives of prominent researchers from anthropology , botany, developmental psychology , the philosophy of biology and science, protozoology, and zoology . The concept of species has played a focal role in both evolutionary biology and the philosophy of biology , and the last decade has seen something of a publication boom on the topic (e.g., Otte and Endler 1989; Ereshefsky 1992b; Paterson 1994; lambert and Spence 1995; Claridge, (...) Dawah, and Wilson 1997; Wheeler and Meier 1999; Howard and Berlocher 1998). (shrink)

When working with garden archaeology and garden archaeobotany, the plant material is of great importance. It is important to be able to identify which plants have grown in a particular garden and which have not, which of the plants you find in the garden today that are newly introduced or have established themselves on their own, and which plants that may be remnants of earlier cultivation. During the past two years, my colleagues and I have been involved in a project (...) that deals with the latter kind of plants, that is, plants that were once actively cultivated and that have survived in their original place of cultivation until the present time(Persson, Ansebo & Solberg, this volume). When we started the project we simply called the plants we worked with ‘relict plants’. This is also the term that has been used unofficially in this field of research for some time. It was in no way an official term, however, and as it turned out, the term already had a different meaning in botany that was both older and better established. We were therefore in need of a better name for the plants we worked with. To single out the plants we were working with, we used the following working definition: “Plants that were once, but are no longer cultivated in a certain area, and where a part of the population still exists even though it is no longer actively maintained”. Although we still think this is a decent approximation, we have realized that there are several complicating factors we have had to think more about. We thus needed both a better name and a better definition. Both these tasks became important parts of the project. (shrink)

Commentary on Andrew Mitchell and Patricia Glazebrook on plants and agriculture in the context of Heidegger's own reflections on botany and technology in which I discuss, bees, cell phone radiation, the relatively complex but fairly obvious sociological dynamics of science and powerful commercial interests (capital), and mantid copulation.

The ethos of Justin Smith’s Nature, Human Nature, & Human Difference is expressed in the narrative of Anton Wilhelm Amo (~1703-53), an African-born​ slave who earned his doctoral degree in Philosophy at a European university and went on to teach at the Universities of Jena and Halle. Smith identifies Amo as a time-marker for diverging interpretations of race: race as inherently tethered to physical difference and race as inherited essential difference. Further, these interpretations of race are fastened to the discourse (...) of science and human diversity within modern Europe. Smith’s thesis maintains that the rise of the concept of race in philosophy begins with a divorcing of the soul from human nature and a movement to a naturalistic classification of human beings through taxonomies (e.g. botany, mineralogy and zoology), which dissolved into this dichotomy: an essential difference between people of reason and people of nature.

We undeniably live in an information age—as, indeed, did those who lived before us. After all, as the cultural historian Robert Darnton pointed out: ‘every age was an age of information, each in its own way’ (Darnton 2000: 1). Darnton was referring to the news media, but his insight surely also applies to the sciences. The practices of acquiring, storing, labeling, organizing, retrieving, mobilizing, and integrating data about the natural world has always been an enabling aspect of scientific work. Natural (...) history and its descendant discipline of biological taxonomy are prime examples of sciences dedicated to creating and managing systems of ordering data. In some sense, the idea of biological taxonomy as an information science is commonplace. Perhaps it is because of its self-evidence that the information science perspective on taxonomy has not been a major theme in the history and philosophy of science. The botanist Vernon Heywood once pointed out that historians of biology, in their ‘preoccupation with the development of the sciences of botany and zoology… [have] diverted attention from the role of taxonomy as an information science’ (Heywood 1985: 11). More specifically, he argued that historians had failed to appreciate how principles and practices that can be traced to Linnaeus constituted ‘a change in the nature of taxonomy from a local or limited folk communication system and later a codified folk taxonomy to a formal system of information science [that] marked a watershed in the history of biology’ (ibid.). A similar observation could be made about twentieth-century philosophy of biology, which mostly skipped over practical and epistemic questions about information management in taxonomy. The taxonomic themes that featured in the emerging philosophy of biology literature in the second half of the twentieth century were predominantly metaphysical in orientation. This is illustrated by what has become known as the ‘essentialism story’: an account about the essentialist nature of pre- Darwinian taxonomy that used to be accepted by many historians and philosophers, and which stimulated efforts to document and interpret shifts in the metaphysical understanding of species and (natural) classification (Richards 2010; Winsor 2003; Wilkins 2009). Although contemporary debates in the philosophy of taxonomy have moved on, much discussion continues to focus on conceptual and metaphysical issues surrounding the nature of species and the principles of classification. Discussions centring on whether species are individuals, classes, or kinds have sprung up as predictably as perennials. Raucous debates have arisen even with the aim of accommodating the diversity of views: is monism, pluralism, or eliminativism about the species category the best position to take? In addition to these, our disciplines continue to interrogate what is the nature of these different approaches to classification: are they representational or inferential roles of different approaches to classification (evolutionary taxonomy, phenetics, phylogenetic systematics)? While there is still much to learn from these discussions—in which we both actively participate—our aim with this topical collection has been to seek different entrypoints and address underexposed themes in the history and philosophy of taxonomy. We believe that approaching taxonomy as an information science prompts new questions and can open up new philosophical vistas worth exploring. A twenty-first century information science turn in the history and philosophy of taxonomy is already underway. In scientific practice and in daily life it is hard to escape the imaginaries of Big Data and the constant threats of being ‘flooded with data’. In the life sciences, these developments are often associated with the socalled bioinformatics crisis that can hopefully be contained by a new, interdisciplinary breed of bioinformaticians. These new concepts, narratives, and developments surrounding the centrality of data and information systems in the biological and biomedical sciences have raised important philosophical questions about their challenges and implications. But historical perspectives are just as necessary to judge what makes our information age different from those that preceded us. Indeed, as the British zoologist Charles Godfray has often pointed out, the piles of data that are being generated in contemporary systematic biology have led to a second bioinformatics crisis, the first being the one that confronted Linnaeus in the mid-18th century (Godfray 2007). Although our aim is to clear a path for new discussions of taxonomy from an information science-informed point of view, we continue where others in the history, philosophy, and sociology of science have already trod. We believe that an appreciation of biological taxonomy as an information science raises many questions about the philosophical, theoretical, material, and practical aspects of the use and revision of biological nomenclatures in different local and global communities of scientists and citizen scientists. In particular, conceiving of taxonomy as an information science directs attention to the temporalities of managing an accumulating data about classified entities that are themselves subject to revision, to the means by which revision is accomplished, and to the semantic, material, and collaborative contexts that mediate the execution of revisions.

An aesthetic and epistemological departure from ocular centrism has occurred in the wake of current technological evolutions and the posthuman turn. The sonic exploration of the more-than-human takes artists and philosophers beyond anthropomorphism to reveal the hidden patterning of life forms and yet-unfathomed universes. The conflation of nature with culture is one shift that takes place when thinking with sounds and rhythm and studying our environments. On an ontological level, a reordering of subject and object occurs when encountering the reciprocal (...) relationship of sounding. What if culture is actually nature? How does technology connect with botany, and what does it mean to engage the environment with the expanded tactility of the ear? This essay observes current inter-species practices in sound art by revisiting philosopher Susanne Langer’s theory of an embodied and embedded mind. Her “new key” in philosophy emphasizes music as a dynamic sound-pattern to conceptualize a semiology of artistic forms that renders human feeling in regard to non-human antecedents. This serves as a tool to trace the preconceptual substrata of mind, leading us through process-oriented studies of nature and psychophysical affect. Thinking with Langer involves the interconnection of natural systems, behavioural patterns, and human expression, which emerges in art. (shrink)

This paper investigates some core aspects of Guy de La Brosse’s botanical work. In the first section, the focus is on the epistemological principles of La Brosse’s botany by analyzing the first and second book of the treatise De la nature, vertu et utilité des plantes. In the second section, the author discusses the role of Paracelsus’s chemistry in La Brosse’s work, with a particular attention to the third book of the De la nature. The final section deals with (...) La Brosse’s interest in the visualization of plants. Here, the author provides the transcription and first Italian translation of a short manuscript related to Abraham Bosse’s engravings for La Brosse’s unfinished book Icones posthumae. (shrink)

Joint practical deliberation is the activity of deciding together what to do. In this dissertation, I argue that several speech acts that we can use to alter our moral obligations – promises, offers, requests, demands, commands, and agreements – are moves within joint practical deliberation. -/- The dissertation begins by investigating joint practical deliberation. The resulting account implies that joint deliberation is more flexible than we usually recognize, in two ways. First, we can make joint decisions not only about what (...) we will do together, but also about what you or I will do alone. Second, we can deliberate by means of two distinct methods: propose-and-ratify, in which a proposed joint decision must be explicitly accepted to come into effect, and propose-and-challenge, in which a proposed joint decision comes into force unless it is explicitly challenged. -/- Varying these parameters generates a botany of different kinds of proposals we can make within joint deliberation. When we look at these proposals more closely, we make a surprising discovery: for each kind of proposal we can make in joint practical deliberation, there is an everyday speech act with the very same properties. A certain kind of proposal to make a joint decision regarding one’s own actions has the same normative effects, under the same conditions, as a promise. One kind of proposal to make a joint decision regarding one’s addressee’s actions has all the essential features of a command; another kind of deliberative proposal – with the same content but a different method of evaluation – looks exactly like a request. And so on. -/- These similarities are too systematic to be coincidental. The only explanation, I argue, is that these ordinary speech acts are identical to their doppelgängers within joint practical deliberation. Promises and offers are proposals to make joint decisions about what I will do. Commands, demands, and requests are proposals to make joint decisions about what you will do. And agreements are joint decisions about what we will do. Call this the deliberative theory of these speech acts. -/- Considering each speech act in turn, I defend the deliberative theory by arguing that it provides a uniquely powerful explanation of its targets’ social and moral significance. Once we see how naturally these speech acts fall out of our practice of joint deliberation, theories that treat them as sui generis – as many moral philosophers now do – will come to seem redundant and nonexplanatory. Conversely, thinking of promises, offers, commands, demands, requests, and agreements as moves within joint practical deliberation allows us to give an elegant and generative theory of these phenomena that have confounded moral philosophers for so long.

L'écologie préénergétique des années 1905-1935 est à la recherche de ses objets d'étude. Des unités fondamentales de la nature (telles que formation végétale, association végétale, climax, biome, communauté biotique, écosystème) se trouvent en compétition et se succèdent les unes aux autres. Autour des années 1920 et 1930, la philosophie organiciste d'Alfred N. Whitehead, ainsi que la perspective évolutionniste d'Herbert Spencer et les propositions émergentistes de Samuel Alexander et Conwy L. Morgan, deviennent des références sous-jacentes au débat épistémologique concernant les unités (...) de base de l'écologie. Des auteurs comme Frederic E. Clements et John Phillips soutiendront plusieurs formes d'organicisme écologique, tandis que Henry A. Gleason interprétera l'association végétale comme le résultat d'une juxtaposition fortuite d'individus. Enfin, et paradoxalement, l'écosystème de Arthur G. Tansley, tout en faisant partie, à l'origine, d'une perspective anti-organiciste, deviendra l'unité fondamentale de programmes de recherche qui se voudront, au moins dans leurs intentions, émergentistes.

In this study, the design and control of a hydraulic system based tire changer machine have been analyzed and simulated using MATLAB/Simulink Toolbox successfully. The machine have a displacement input which is a leg pedal displacement in order to push the piston of the pump to fed the motor with a pressured hydraulic fluid to rotate the tire with an angular speed to mount and dismount it. Augmentation based H4 and H2 optimal synthesis controllers have been used to improve the (...) performance of the machine. Comparison of the proposed controllers for tracking a reference input speed have been done using two reference inputs (step and random) signals. Finally, the comparative simulation results proved the effectiveness of the proposed tire changer with synthesis controller in improving the settling time and percentage overshoot. (shrink)

Background: One of the all-time questions in evolutionary biology regards the evolution of organismal shapes, and in particular why certain forms appear repeatedly in the history of life, others only seldom and still others not at all. Recent research in this field has deployed the conceptual framework of constraints and natural selection as measured by quantitative genetic methods. Scope: In this paper I argue that quantitative genetics can by necessity only provide us with useful statistical sum- maries that may lead (...) researchers to formulate testable causal hypotheses, but that any inferential attempt beyond this is unreasonable. Instead, I suggest that thinking in terms of coordinates in phenotypic spaces, and approaching the problem using a variety of empirical methods (seeking a consilience of evidence), is more likely to lead to solid inferences regarding the causal basis of the historical patterns that make up most of the data available on phenotypic evolution.
