Biological evolution is a complex blend of ever changing structural stability, variability and emergence of new phe- notypes, niches, ecosystems. We wish to argue that the evo- lution of life marks the end of a physics world view of law entailed dynamics. Our considerations depend upon dis- cussing the variability of the very ”contexts of life”: the in- teractions between organisms, biological niches and ecosys- tems. These are ever changing, intrinsically indeterminate and even unprestatable: we do not know ahead of (...) time the ”niches” which constitute the boundary conditions on selec- tion. More generally, by the mathematical unprestatability of the ”phase space”, no laws of mo- tion can be formulated for evolution. We call this radical emergence, from life to life. The purpose of this paper is the integration of variation and diversity in a sound concep- tual frame and situate unpredictability at a novel theoretical level, that of the very phase space. Our argument will be carried on in close comparisons with physics and the mathematical constructions of phase spaces in that discipline. The role of symmetries as invariant preserving transformations will allow us to under- stand the nature of physical phase spaces and to stress the differences required for a sound biological theoretizing. In this frame, we discuss the novel notion of ”enablement”. Life lives in a web of enablement and radical emergence. This will restrict causal analyses to differential cases. Mutations or other causal differ- ences will allow us to stress that ”non conservation princi- ples” are at the core of evolution, in contrast to physical dynamics, largely based on conservation principles as sym- metries. Critical transitions, the main locus of symmetry changes in physics, will be discussed, and lead to ”extended criticality” as a conceptual frame for a better understanding of the living state of matter.

In addition to being one of the world's most influential philosophers, Aristotle can also be credited with the creation of both the science of biology and the philosophy of biology. He was the first thinker to treat the investigations of the living world as a distinct inquiry with its own special concepts and principles. This book focuses on a seminal event in the history of biology - Aristotle's delineation of a special branch of theoretical knowledge devoted to the systematic investigation (...) of animals. Aristotle approached the creation of zoology with the tools of subtle and systematic philosophies of nature and of science that were then carefully tailored to the investigation of animals. The papers collected in this volume, written by a pre-eminent figure in the field of Aristotle's philosophy and biology, examine Aristotle's approach to biological inquiry and explanation, his concepts of matter, form and kind, and his teleology.

The realism grounding St. Thomas Aquinas’s pre-modern natural science defends the reception of similitudes of the forms of things known by abstraction. Modern natural science challenges this abstractio- nist account by recasting «form» in the leading role of principle of intelligibility—instead of forms, modern science discovers laws. Thomistic realism is prima facie incompatible with this account. Following Charles De Koninck, this essay outlines a rapprochement between the epistemology of pre-modern, Thomistic natural science and its modern successor. I argue that natural (...) forms are noetic limits towards which physical laws tend, and our grasp of this tendency uses a mode of knowledge comparable to what St. Thomas termed universal in repraesentando.

The concept of facticity denotes conditions of experience whose necessity is not logical yet whose contingency is not empirical. Although often associated with Heidegger, Fichte coins ‘facticity’ in his Berlin period to refer to the conclusion of Kant’s metaphysical deduction of the categories, which he argues leaves it a contingent matter that we have the conditions of experience that we do. Such rhapsodic or factical conditions, he argues, must follow necessarily, independent of empirical givenness, from the I through a (...) process of ‘genesis.’ I reconstruct Fichte’s argument by tracing the origin of his neologism, presenting his Jena critique of Kant’s rhapsodic appeal to the forms of judgment, and illustrating the Jena period’s continuity with the Berlin period’s genetic method, while noting a methodological shift whereby Fichte directs his critique against his own doctrine of intellectual intuition in order to eliminate its ‘factical terms.’.

Many accounts of the historical development of neurological criteria for determination of death insufficiently distinguish between two strands of interpretation advanced by advocates of a "whole-brain" criterion. One strand focuses on the brain as the organ of integration. Another provides a far more complex and nuanced account, both of death and of a policy on the determination of death. Current criticisms of the whole-brain criterion are effective in refuting the first interpretation, but not the second, which is advanced in the (...) 2008 President's Council report on the determination of death. In this essay, I seek to further develop this second strand of interpretation. I argue that policy on determination of death aligns moral, biological, and ontological death concepts. Morally, death marks the stage when respect is no longer owed. Biologically, death concerns integrated functioning of an organism as a whole. But the biological concepts are underdetermined. The moral concerns lead to selection of strong individuality concepts rather than weak ones. They also push criteria to the "far side" of the dying process. There is a countervailing consideration associated with optimizing the number of available organs, and this pushes to the "near side" of death. Policy is governed by a conviction that it is possible to align these moral and biological death concepts, but this conviction simply lays out an agenda. There is also a prescription—integral to the dead donor rule—that lexically prioritizes the deontic concerns and that seeks to balance the countervailing tendencies by using science-based refinements to make the line between life and death more precise. After showing how these concerns have been effectively aligned in the current policy, I present a modified variant of a "division" scenario and show how an "inverse decapitation problem" leads to a conclusive refutation of the nonbrain account of death.

This book presents G. A. Cohen's Gifford Lectures, delivered at the University of Edinburgh in 1996. Focusing on Marxism and Rawlsian liberalism, Cohen draws a connection between these thought systems and the choices that shape a person's life. In the case of Marxism, the relevant life is his own: a communist upbringing in the 1940s in Montreal, which induced a belief in a strongly socialist egalitarian doctrine. The narrative of Cohen's reckoning with that inheritance develops through a series of sophisticated (...) engagements with the central questions of social and political philosophy. In the case of Rawlsian doctrine, Cohen looks to people's lives in general. He argues that egalitarian justice is not only, as Rawlsian liberalism teaches, a matter of rules that define the structure of society, but also a matter of personal attitude and choice. Personal attitude and choice are, moreover, the stuff of which social structure itself is made. Those truths have not informed political philosophy as much as they should, and Cohen's focus on them brings political philosophy closer to moral philosophy, and to the Judeo-Christian ethical tradition, than it has recently been.

‘No matter what the grievance, and I'm sure that the Palestinians have some legitimate grievances, nothing can justify the deliberate targeting of innocent civilians.

Unexpected discoveries in nonequilibrium physics and nonlinear dynamics are changing our understanding of complex phenomena. Recent research has revealed fundamental new properties of matter in far-from-equilibrium conditions, and the prevalence of instability-where small changes in initial conditions may lead to amplified effects.

This book addresses a wide range of topics relating to the properties and behavior of condensed matter under extreme conditions such as intense magnetic and electric fields, high pressures, heat and cold, and mechanical stresses. It is divided into four sections devoted to condensed matter theory, molecular chemistry, theoretical physics, and the philosophy and history of science. The main themes include electronic correlations in material systems under extreme pressure and temperature conditions, surface physics, the transport properties of low-dimensional (...) electronic systems, applications of the density functional theory in molecular systems, and graphene. The book is the outcome of a workshop held at the University of Catania, Italy, in honor of Professor Renato Pucci on the occasion of his 70th birthday. It includes selected invited contributions from collaborators and co-authors of Professor Pucci during his long and successful career, as well as from other distinguished guest authors. (shrink)

Modern science faces a series of problems that undermine confidence in its reliability. To solve these problems, we must reflect on what makes science work and what leads it astray. This book is about Science, its strengths and weaknesses. The papers that scientists write form a vast resource of evidence and theory that is doubling about every ten years, along with the number of scientists. The size of this resource makes it hard for it to be used effectively by scientists, (...) and along with this are growing concerns about its integrity and reliability. This book looks at the scientific method, as currently applied and as understood philosophically by scientists, the social structure of science, and the structure of scientific communication through journals. It includes case studies of controversies, and looks at how fields develop over time. (shrink)

Fetal pain has long been a contentious issue, in large part because fetal pain is often cited as a reason to restrict access to termination of pregnancy or abortion. We have divergent views regarding the morality of abortion, but have come together to address the evidence for fetal pain. Most reports on the possibility of fetal pain have focused on developmental neuroscience. Reports often suggest that the cortex and intact thalamocortical tracts are necessary for pain experience. Given that the cortex (...) only becomes functional and the tracts only develop after 24 weeks, many reports rule out fetal pain until the final trimester. Here, more recent evidence calling into question the necessity of the cortex for pain and demonstrating functional thalamic connectivity into the subplate is used to argue that the neuroscience cannot definitively rule out fetal pain before 24 weeks. We consider the possibility that the mere experience of pain, without the capacity for self reflection, is morally significant. We believe that fetal pain does not have to be equivalent to a mature adult human experience to matter morally, and so fetal pain might be considered as part of a humane approach to abortion.

Nothing about Xenophon's Hellenica is more outrageous than his treatment of the relations of Persia and the Greeks. It was orthodoxy in the circle of Agesilaus that Theban medizing, barbarismos, had sabotaged the plans for a glorious anabasis and recalled him to the defence of his city . Not until the Thebans woo and win the fickle favour of the King , does anything like detail emerge. In the regrettable interlude, the less said the better. If the third speech of (...) Andocides had not survived, there would have been some tangled theorizing about a note in Didymus , especially as regards ‘the ambassadors who in Sparta consented’, but sober historical judgement would never have transgressed so far from the text of Xenophon as to postulate a Peace Congress in Sparta as well as in Sardis in 392. Likewise, the merest chance of epigraphic survival assures us that the oaths, which the ‘Athenians and the Spartans and the other Greeks’ swore in 387/6, ‘the King swore’ — and so on. If we did not have the reflection of Ephorus in Diodorus, albeit a mirror cracked and blemished, we would be sadly astray in 375 and 371. When, however, the despicable Thebans become the King's favoured power, disgraceful scenes unfold. ‘Pelopidas very much had things his own way with the Persian; he could say that the Thebans alone of the Greeks had fought on the King's side at Plataea, that they had never afterwards campaigned against him, that the Spartans were at war with them because they would not join Agesilaus…etc.’ . A Persian is found at Thebes reading out the contents of a Royal Rescript, after displaying the Royal seal ; at Sparta twenty years before, such details had been left to the imagination. The cause of Xenophon's method in this matter is not for the moment under discussion, but rather the consequence, viz. our uncertainty about what precisely the King's Peace said. There was a document, inscribed on stone pillars and displayed in the national shrines . If ever a copy turns up, what can we expect to find? The measure of our uncertainty was provided by Wilcken, who produced a curious hypothesis which found little sympathy; that he could do so shows the state of the evidence. Some effort of the imagination is needed, and those who gravely disapprove of conjectures of what might have been the case need read no further. At the end one can be sure of very little. Conjectures, however, have been uttered, en passant, elsewhere. What may prove to be a chorus of disdain has begun. A formal confession may be welcome. (shrink)

Aldo Antonelli offers a novel view on abstraction principles in order to solve a traditional tension between different requirements: that the claims of science be taken at face value, even when involving putative reference to mathematical entities; and that referents of mathematical terms are identified and their possible relations to other objects specified. In his view, abstraction principles provide representatives for equivalence classes of second-order entities that are available provided the first- and second-order domains are in the equilibrium dictated by (...) the abstraction principles, and whose choice is otherwise unconstrained.entities are the referents of abstraction terms: such referents are to an extent indeterminate, but we can still quantify over them, predicate identity or non-identity, etc. Our knowledge of them is limited, but still substantial: we know whatever has to be true no matter how the representatives are chosen, i.e., what is true in all models of the corresponding abstraction principles. This view is backed up by an “austere” conception of universals, according to which these are first-order objects, i.e., ways of collecting first-order objects. Antonelli thus claims that second-order logic does not import any novel ontological commitment beyond ontology of first-order, naturalistically acceptable, objects. Moreover, in the case of arithmetic, even if Hume’s Principle is construed as described above, Frege’s Theorem goes through unaffected, since there is nothing in its proof that depends on an account of the “true nature” of numbers. A viable construal of logicism is then given by the combination of semantic nominalism and a naturalistic conception of abstraction. [Editors note]. (shrink)

This article is an attempt to clarify a confusion in the brain death literature between logical sufficiency/necessity and natural sufficiency/necessity. We focus on arguments that draw conclusions regarding empirical matters of fact from conceptual or ontological definitions. Specifically, we critically analyze arguments by Tom Tomlinson and Michael B. Green and Daniel Wikler. which, respectively, confuse logical and natural sufficiency and logical and natural necessity. Our own conclusion is that it is especially important in discussing the brain death issue to observe (...) the distinction between logical and natural sufficiency/necessity in a strict fashion.

Plutarch of Chaeronea was a voluminous writer whose experience of the Graeco-Roman world of his own day was quite as comprehensive as his knowledge of earlier ages. The ancient historian is often daunted by the sheer bulk of Plutarch's work and prefers customarily to concentrate his attention upon the Lives, which, if not history, at least contain much historical matter.

The nature of Marx's ethics has been a matter of considerable dispute since the latter part of the nineteenth century. Some have maintained that Marx had no ethics; others have claimed that his ethics is Kantian; and yet others have maintained that his ethics is utilitarian. The first two views were prominent at the turn of the century. It is the utilitarian view that seems to hold favor among a great many today. Thus Adam Schaff has claimed that ‘Marxist (...) theory … leads to the general position that may be called “social hedonism” —the view that the aim of human life is to secure the maximum happiness for the broadest masses of the people … ’ Similarly, Derek Allen has claimed that ‘it is possible … to show that the arguments which support [Marx's and Engels’] moral judgments are utilitarian in all but name.’.

For the past two decades, my research has primarily focused on two interrelated questions: 1)What do the data from mysticism and non-ordinary states of consciousness imply about the nature of consciousness understood broadly? 2) In what ways does a careful examination of the nature of consciousness illuminate the processes that undergird mysticism and non-ordinary states of consciousness? In my attempts to offer coherent, cogent, and compelling answers to these questions, I have been helped, immeasurably, by the work of William James (...) and Henri Bergson. I have already written a book on each figure,1 so I am keenly aware that this essay will be unable to encapsulate, even partially, the richness and depth of their respective perspectives on this provocative subject matter. Nonetheless, I am delighted to have been given the opportunity to underscore some of the insights offered by James and Bergson that over the years have continued to inspire me. (shrink)

In the Critique of the Power of Judgment, Kant diagnoses an antinomy of taste: either determinate concepts exhaust judgments of taste or they do not. That is to say, judgments of taste are either objective and public or subjective and private. On the objectivity thesis, aesthetic value is predicable of objects. But determining the concepts that would make a judgment of taste objective is a vexing matter. Who can say which concepts these would be? To what authority does one (...) appeal? On the subjectivity thesis, aesthetic value is not predicable of objects. But this threatens judgments of taste with a sort of relativism. Can we not firmly assert the aesthetic value of any object? Have we no authority to make criticisms of taste? Following John McDowell’s “Aesthetic Value, Objectivity and the Fabric of the World”, I will hold that aesthetic value is neither objective nor subjective, but rather intersubjective. But, contra McDowell, I will argue that the validity that intersubjective aesthetic value bestows on judgments of taste must assume an indeterminate absolute conception of reality, of the world as it is in itself. Only such a conceptual resource can in turn make intelligible the notion of a shared or common sense according to which a judgment of taste can be universally valid, that is, valid for all subjects. Finally, I will consider an objection to common sense in matters of taste. (shrink)

This paper examines conceptual issues that arise in applications of Darwinian natural selection to cultural systems. I argue that many criticisms of cultural selectionist models have been based on an over-detailed reading of the analogy between biological and cultural units of selection. I identify five of the most powerful objections to cultural selection theory and argue that none cuts to its heart. Some objections are based on mistaken assumptions about the simplicity of the mechanisms of biological heredity. Other objections are (...) attributable, rather, to mistaken inferences from observations of biological subject matter to what is essential in natural selection. I argue that such features are idiosyncratic of biological systems, but not essential for natural selection. My arguments throughout are illustrated by examples from biological and cultural evolution, and counter-factual illustrations from the history of theoretical biology.

If we accept the Socratic edict that the examined life is the only worth living, we find no examination can exclude that mortal fate of human life. If we define a philosophical problem as, in Hans Jonas’ words, “the collision between a comprehensive view (be it hypothesis or belief) and a particular fact which will not fit into it”, we see there can be no greater problem for materialism or organicism than the corpse. That living things die is a problem (...) for a view on which only a figment of the imagination differentiates organic from inorganic matter, as for a view on which life is rational and eternal. For any systematic view, the body is a constant reminder of an acceptable answer to the question 'what is being'. This is because the body that can die is the ultimate explanatory task for any principled answer to this question. (shrink)

The essays in this book offer an in-depth exploration of value theory. Portions examine the theoretical foundations of values and valuation exploring the rational groundwork for judgments. Other aspects, appealing to value distinctions of inherent, intrinsic, and instrumental, bring to light matters of aesthetic, social political, ethical, and ontological issues.

MATERIALISTS claim that in principle mentality could be accounted for entirely by properties of matter. They must, of course, clarify, as far as possible, the precise scope of the concept "properties of matter." According to materialists there exists only one type of "substance" in the universe, namely matter. Sophisticated experimental and theoretical analyses have led contemporary physicists to interpret known material entities as being composed of two classes of elementary particles, namely quarks and leptons and constituents of (...) interaction fields that mediate interactions between some or all of the elementary particles and which comprise photons, gluons, intermediate bosons and gravitons. For instance, protons and neutrons are composed--by hypothesis--of quarks, while electrons are probably the most familiar leptons. Whether any analyzed and postulated elementary particles and constituents of interaction fields are "ultimate" components of matter can never be known. It remains always possible that more basic subcomponents of known components will be discovered. This has happened repeatedly throughout the history of physics. Hence, what physicists understand by the "physical properties" of the basic components of matter must always remain expressed in terms of usually intricate hypothetico-deductive theories which are tentative and fallible. Contemporary relativistic quantum mechanics of elementary particles and of interaction fields provide typical examples of such hypothetico-deductive theories relating to present known basic components of matter.

It is generally unquestioned that human subjects research review boards should assess the ethical acceptability of protocols. It says so right on the tin, after all: they are explicitly called research ethics committees in the UK. But it is precisely those sorts of unchallenged assumptions that should, from time to time, be assessed and critiqued, in case they are in fact unfounded. John Stuart Mill's objection to suppressers of dissent is instructive here: “If the opinion is right, they are deprived (...) of the opportunity of exchanging error for truth: if wrong, they lose, what is almost as great a benefit, the clearer perception and livelier impression of truth, produced by its collision with error”.1 Andrew Moore and Andrew Donnelly's compelling article, “The job of ‘ethics committees’”, is just this sort of challenge to conventional wisdom, a rejection of the notion that review boards should be considering ethical matters at all.2 If true, we should be substantially reforming our research ethics policies. And if false, rebuttals would help strengthen and ground the otherwise unquestioned assumption of the role of ethics committees. As it happens, I will argue that their critiques fall into the second category. While mistaken, they present a valuable opportunity to clarify the role of ethics committees and their relationship to relevant codes. In particular, I will defend a hybrid account where codes have strict primacy, but leave significant room for review boards …. (shrink)

In an old paper of our group in Milano a formalism was introduced for the continuous monitoring of a system during a certain interval of time in the framework of a somewhat generalized approach to quantum mechanics. The outcome was a distribution of probability on the space of all the possible continuous histories of a set of quantities to be considered as a kind of coarse grained approximation to some ordinary quantum observables commuting or not. In fact the main aim (...) was the introduction of a classical level in the context of QM, treating formally a set of basic quantities, to be considered as beables in the sense of Bell, as continuously taken under observation. However the effect of such assumption was a permanent modification of the Liouville-von Neumann equation for the statistical operator by the introduction of a dissipative term which is in conflict with basic conservation rules in all reasonable models we had considered. Difficulties were even encountered for a relativistic extension of the formalism. In this paper I propose a modified version of the original formalism which seems to overcome both difficulties. First I study the simple models of an harmonic oscillator and a free scalar field in which a coarse grain position and a coarse grained field respectively are treated as beables. Then I consider the more realistic case of spinor electrodynamics in which only certain coarse grained electric and magnetic fields are introduced as classical variables and no matter related quantities.

In domestic scientific and public opinion, interest in religion as a new worldview paradigm is very high. Today's attention to the Christian religion in our society is connected, in our opinion, with the specificity of its value system, which distinguishes it from other forms of consciousness: the idea of ​​God, the absolute, the eternity of moral norms. That is why its historical forms do not receive accurate characteristics and do not matter in the mass consciousness. Modern religious beliefs do (...) not always arise as a result of the direct influence of church preaching. The emerging religious values ​​are absorbed in a wide range of philosophical, artistic, ethical ideas, acting as a compensation for what is generally defined as spirituality. At the same time, the appeal to Christian values ​​became very popular. (shrink)

In 1916, Einstein rederived the blackbody radiation law of Planck that originated the idea of quantized energy one hundred years ago. For this purpose, Einstein introduced the concept of transition probability, which had a profound influence on the development of quantum theory. In this article, we adopt Einstein's assumptions with two exceptions and seek the statistical condition for the thermal equilibrium of matter without referring to the inner details of either statistical thermodynamics or quantum theory. It is shown that (...) the conditions of thermodynamic equilibrium of electromagnetic radiation and the energy balance of thermal radiation by the matter, between any of its two energy-states, not only result in Planck's radiation law and the Bohr frequency condition, but they remarkably yield the law of the statistical thermal equilibrium of matter: the Maxwell–Boltzmann distribution. Since the transition probabilities of the modern quantum theory of radiation coincide with their definition in Einstein's theory of blackbody radiation, the presented deduction of the Maxwell–Boltzmann distribution is equally valid within the bounds of modern quantum theory. Consequently, within the framework of the fundamental assumptions, the Maxwell–Boltzmann distribution of energy-states is not only a sufficient, but a necessary condition for thermal equilibrium between the matter and radiation.

On one way of talking about a traditional metaethical topic, realists accept that some items appear on the list of what exists in the moral or more broadly normative domain of inquiry. They then divide over whether those items are like what science and experience suggest that all other items on the list of what exists across all domains are like – naturalistic and secular. Reductive naturalists answer this further question affirmatively. Why don’t nonnaturalists? I explore the answer that it’s (...) because normative entities are “just too different” in the sense that they are countably different things. However, I argue that this answer rests on the subtle presupposition that the normative domain doesn’t also contain uncountable entities of the sort that analytic metaphysicians call “stuff”. Taking intuitions of difference seriously points the way to a novel form of metaethical reductive naturalism. The key is to identify the stuff that matters. (shrink)

In a recent article Duncan Purves, Ryan Jenkins, and B. J. Strawser argue that in order for a decision in war to be just, or indeed the decision to resort to war to be just, it must be the case that the decision is made for the right reasons. Furthermore, they argue that this requirement holds regardless of how much good is produced by said action. In this essay I argue that their argument is flawed, in that it mistakes what (...) makes an agent morally good for what makes an act morally good. I argue that the main thrust of Purves et al.’s argument in fact undermines the conclusion they wish to draw, and that the reasons for one’s action do not make an in principle difference to the morality of actions in war. I further argue that this position undermines the traditional ad bellum just war constraint of right intention, and that the morality of actions in war is, at core, only concerned with outcomes. I conclude by clarifying that one’s reasons for action do in fact matter when deciding to enter war or kill in war, but only because one’s reasons significantly impact the way in which one acts. The purpose of this paper is to clear the theoretical space by showing why intentions/reasons do not in principle matter when assessing the morality of war (or killing), but this should not be taken as an argument that we should ignore intentions/reasons altogether.

Originally published in 1931, this book forms the first of two volumes based on the Gifford Lectures delivered at the University of Edinburgh in 1919 and 1921. The second volume, God and Nature, was originally published in 1952.

Throughout this discussion, a carefully defined 'common sense' position is put forward as the (...) mediating factor in the relationship between the mind and the material world. This book will be of value to anyone with an interest in philosophy, psychology and theories of knowledge. (shrink)
