Bringing together the latest scientific advances and some of the most enduring subtle philosophical puzzles and problems, this book collects original historical and contemporary sources to explore the wide range of issues surrounding the nature of life. Selections ranging from Aristotle and Descartes to Sagan and Dawkins are organised around four broad themes covering classical discussions of life, the origins and extent of natural life, contemporary artificial life creations and the definition and meaning of ' (...) class='Hi'>life' in its most general form. Each section is preceded by an extensive introduction connecting the various ideas discussed in individual chapters and providing helpful background material for understanding them. With its interdisciplinary perspective, this fascinating collection is essential reading for scientists and philosophers interested in astrobiology, synthetic biology and the philosophy of life.

ABSTRACT The article critically discusses Rahel Jaeggi’s recent philosophical contribution to a critical theory of capitalism. The first part reconstructs Jaeggi’s account of Lebensform, life-form, that builds up the main ontological framework for addressing and problematizing capitalism intended not as an economic system but as a social whole. The second part focuses on the three different theoretical strategies that Jaeggi puts forward to detect and deal with capitalism’s immanent flaws. The third and last part problematizes the metaphysical assumptions and (...) implications of Jaeggi’s understanding of life-form and outlines a more dialectical, or “transactional” notion of form of life, which is inspired by Dewey’s non-reductionist naturalist method of inquiry. The overall aim is to strengthen the philosophical critique of the capitalist form of life. (shrink)

Even inanimate bodies, to be sure, have a certain amount of freedom. Insofar as they are definite things they maintain their integrity against the tendency to be reabsorbed into the Indefinite. Even a gas preserves its mass, a liquid preserves also its volume, and a solid preserves even its shape, in the face of a hostile environment. But the motion of an inanimate body is determined by the outer forces acting on it. This fact is formulated by the classical laws (...) of motion. The law of inertia states that a body left to its own devices will not change its motion. The law of force states that a body not left to its own devices will change its motion in a direction and to an extent determined by the imposed force. The law of reaction states that a body will not kick back any harder than it is kicked. (shrink)

The Life of St AEthelwold is one of the most important and interesting sources for the history of Anglo-Saxon England and for the religious movements of western Europe in the tenth century. It was written around the year 1000 by Wulfstan of Winchester, who had been a student of AEthelwold; the Life, therefore, provides a firsthand account of the activities of the man who was the central force in the Benedictine reform movement of the later tenth century. It (...) also reveals the nature of AEthelwold's education and contacts with continental monasticism, and shows why Winchester became a focal point of late Anglo-Saxon culture. The present book, by two well-known authorities in the field of Anglo-Latin literature, provides the first critical edition of Wulfstan's Life. It is accompanied by a translation, extensive historical notes, and a substantial introduction which treats both Wulfstan and Aethelwold in the light of recent scholarly research. Appendices provide editions of other texts relevant to the study of AEthelwold, including a Latin Life by his pupil AElfric, some verses by a twelfth-century Ely poet, and a previously unprinted Middle English poem on the saint. This is a valuable edition of a major source, which will be welcomed by all students of Anglo-Saxon England. (shrink)

Is one of the roles of theory in biology answering the question “What is life?” This is true of theory in many other fields of science. So why should not it be the case for biology? Yet efforts to identify unifying concepts and principles of life have been disappointing, leading some (pluralists) to conclude that life is not a natural kind. In this essay I argue that such judgments are premature. Life as we know it on (...) Earth today represents a single example and moreover there is positive evidence that it may be unrepresentative of life considered generally. Furthermore, as I discuss, the prototype for theorizing about life has traditionally been based on multicellular plants and animals. Yet biologists have discovered that the latter represent a rare, exotic, and fairly recent form of Earth life. By far the oldest, toughest, most extensive, and diverse form of life on our planet is unicellular, prokaryotic microbes, and there are reasons to suppose that this is almost certainly true elsewhere in the universe as well. If there are explanatorily and predictively powerful, biologically distinctive principles for life that can be gleaned from our insular example of life it is more likely that they will be found among the microbes. I discuss some provocative ways in which unicellular microbes differ from multicellular eukaryotes and argue that some of them just might provide us with key insights into the nature of life.

On Thursday, August 21, 1862, Edmond and Jules de Goncourt registered in their Journal a short entry on the nature of life: “Qu’est-ce que la vie? L’usufruit d’une agrégation de molecules”—What is life? The usufruct of an aggregation of molecules. Although the extraordinary chronicles of the social and cultural life of the Second French Empire written by the Goncourt brothers includes names of their most distinguished contemporaries, the writers, artists, politicians and socialites they befriended outnumber by (...) far the scientists. It is almost certain that they were never close to Felix Dujardin, a distinguished microbiologist and member of the French Academy of Sciences. In 1835, Dujardin had started crushing ciliates under the microscope and observed that the tiny cells exuded a jellylike substance, which he described as a “gelée vivante” and was eventually named “protoplasm” by Johann E. Purkinje and Hugo von Mohl. The small note written by the Goncourts in their journal is an indica. (shrink)

Fractals are built from patterns generated from immense complexity within the resonant frequencies that connect and tune the universe. Play of such frequencies would result in the exchange of energy and coupling of informational systems at various levels and scales. The present essay serves as a small ride into life’s association with such phenomenon. At a fundamental level communication happens via process called ‘resonance’, and this in turn manifests at a physical level as self-replicating and self-resonating patterns called ‘fractals.’ (...) This could be the reason why at a physical level every structure carries this fractal imprint nature, making it the cosmic signature. The fractal patterns popping out in the natural world surrounding us could be thought of as frozen energy or resonant life patterns. Thus, we hypothesize life could have emerged or appeared as a ‘fracto-resonant’ phenomenon, resulting from the play of interference between material and non-material aspects. In this regard, we propose frequencies or vibrations to be more fundamental to life and call for scientific studies that aim at understanding the effect of various frequencies and vibrations on life forms and consciousness.

The aim of this paper is to examine Francis Glisson’s theory of perception insofar as it concerns the lowest class of living beings: plants. Plants have a special status, they are located between inanimate objects and animals in the hierarchy of being. Unlike the former, they are organic, but unlike the latter they are unconscious. Peculiar to Glisson is the claim that vegetative organization requires self-referential perception. In light of traditional epistemology, this claim may sound puzzling, because we tend to (...) associate self-representation with conscious thought. In order to make sense of Glisson’s self-referential, but unconscious perceptions, the first part of the paper investigates the role of perception in the vegetative process of organization. The second part is a comparative study on two ways of drawing the distinction between unconscious perceptions and conscious sensations. The first one is the Cartesian approach as outlined by Antoine Arnauld in the early 1680s, the second one is Glisson’s theory. In light of the comparison it is argued that Glisson’s is a higher order theory of sensation in which the phenomenon of consciousness requires the delimitation of the all-inclusive, self-referential nature of perception.

We distinguish dynamical and statistical interpretations of evolutionary theory. We argue that only the statistical interpretation preserves the presumed relation between natural selection and drift. On these grounds we claim that the dynamical conception of evolutionary theory as a theory of forces is mistaken. Selection and drift are not forces. Nor do selection and drift explanations appeal to the (sub-population-level) causes of population level change. Instead they explain by appeal to the statistical structure of populations. We briefly discuss the implications (...) of the statistical interpretation of selection for various debates within the philosophy of biologythe `explananda of selection' debate and the `units of selection' debate.

It is emphasized that environmental predictability is another important condition that plays roles in slow strategies that are related to innovation; that economic inequality, except as measured by Gross Domestic Product per capita, influences innovation; and that switching global life history from a slow to a fast strategy is a response adopted in response to new challenges during the post-Industrial Revolution period.
