The early evolution of metazoans is a major focus of biological attention, but is the historical record revealed in the Cambrian “explosion” an accurate reflection of original events? The key questions concern the nature of the earliest animals and when they originated. One widely-mooted suggestion is that planktotrophic larvae, typified by the annelidan trochophore and echinoid pluteus, existed long before the metazoan radiations evident in the Cambrian fossil record. This idea could be consistent for recent evidence of divergence times, based (...) on molecular “clocks,” of phyla appearing well before the Cambrian. Now a surprising new discovery of eggs with blastomeres and embryos with well-defined anatomy from the Cambrian (c.530 Myr ago) of China and Siberia promises to extend the arena of debate. In one case a convincing ontogeny can be traced from eggs to adult tube-dwelling cnidarians. In the other example a possible protostome, unhatched and wrapped around the egg, shows segmentation and possibly nascent sclerites. In both, these cases development is direct, i.e., there is no evidence for any planktotrophic larval stage. The implications for our perceptions of both the Cambrian ‘explosion’ and metazoan phylogeny could be considerable. BioEssays 20:676–682, 1998.© 1998 John Wiley & Sons Inc. (shrink)

In recent years, two schools of thought have emerged with regard to the Cambrian “explosion”. One argues that it was very quick, with phyla tumbling into existence in a virtual geological instant. The other view has a more relaxed temporal perspective. It looks to slow aeons of cryptic metazoan history, which led to a final breakthrough in the Cambrian, not in evolution but of fossilization potential. Yet both views have serious difficulties. Now, in a recent issue of Biological Reviews, Graham (...) Budd and Sören Jensen(1) argue for a third way. In an intriguing blend of functional morphology, the fossil record and cladistic thinking, they suggest that the assembly of metazoan bodyplans took place in a surprisingly straightforward manner.

e live on a wonderful planet that not only teems with life but shows a marvellous exuberance of form and variety. In comparison with the size of the Earth its living skin (the so-called biosphere) may be thin, but it is by no means negligible. From high in the atmosphere, where ballooning spiders wafted aloft on their silk-strings have been trapped at heights of more than 4500 m and birds such as condors cross tropical storms at altitudes well above 6000 (...) in, via the oceans and the green continents, to deep within the Earth's crust where bacteria are known to live at depths of at least several kilometres, life is pervasive.

Simon Conway Morris, noted Cambridge University paleontologist, argues that in evolutionary natural history humans (or beings rather like humans) are an inevitable outcome of the developing speciating processes over millennia; humans are “inherent” in the system. This claim, in marked contrast to claims about contingency made by other prominent paleontologists, is based on numerous remarkable convergences—similar trends found repeatedly in evolutionary history. Conway Morris concludes approaching a natural theology. His argument is powerful and informed. But (...) does it face adequately the surprising events in such history, particularly notable in unexpected co‐options that redirect the course of life? The challenge to understand how humans are both on a continuum with other species and also utterly different remains a central puzzle in paleontology. (shrink)

Conway Morris argues against Stephen Jay Gould's argument that the history of life is radically contingent by describing the abundance of convergences, wherein different lineages starting in different states, arrive at the same adaptations. A standard example is the evolution of the camera eye. This review assesses the validity of Conway Morris' argument.

Debating the interpretation of the Burgess Shale fossil records, Stephen Jay Gould and Simon Conway Morris have formulated two conflicting theses regarding the nature of evolutionary processes. While Gould argued that evolution is essentially a contingent process whose outcomes are unpredictable, Conway Morris claimed that the omnipresence of convergence testifies that it is in fact deterministic, leading to predictable and inevitable outcomes. Their theses have been extensively researched from various perspectives. However, a systematic parallel analysis (...) of the core arguments each of them offered in support of their thesis has been lacking. I argue Conway Morris has successfully exposed the core weaknesses of Gould's thesis and offered a comprehensive account in favor of the major role of convergence in evolutionary history. On the other hand, I will point out some of the weak points in the latter's arguments supporting the deterministic view of life's evolution. Although Conway Morris has been more successful in arguing for the deterministic nature of the evolutionary processes, both theses could be improved if their shortcomings are taken into consideration.

On the basis of three physical axioms, we prove that if the choice of a particular type of spin 1 experiment is not a function of the information accessible to the experimenters, then its outcome is equally not a function of the information accessible to the particles. We show that this result is robust, and deduce that neither hidden variable theories nor mechanisms of the GRW type for wave function collapse can be made relativistic and causal. We also establish the (...) consistency of our axioms and discuss the philosophical implications. (shrink)

We respond to criticisms of our paper “The Free Will Theorem”, and produce a new form of the theorem based on weaker assumptions.

We prove a no-triplets theorem for spin 1 particles, which implies a strengthened form of the no-cloning theorem.

This is a collection of chapters by some of the most influential memory researchers.

The term 'episodic memory' refers to our memory for unique, personal experiences, that we can date at some point in our past - our first day at school, the day we got married. It has again become a topic of great importance and interest to psychologists, neuroscientists, and philosophers. How are such memories stored in the brain, why do certain memories disappear (especially those from early in childhood), what causes false memories (memories of events we erroneously believe have really taken (...) place)? Since Endel Tulving's classic book 'Episodic memory' (OUP, 1983) very few books have been published on this topic. In recent years however, many of the assumptions made about episodic memory have had to be reconsidered as a result of new techniques, which have allowed us a far deeper understanding of episodic memory. In 'Episodic memory: new directions in research' three of the worlds leading researchers in the topic of memory have brought together a stellar team of contributors from the fields of cognitive psychology, neuropsychology, and neuroscience, to present an account of what we now know about about this fundamentally important topic. The list of contributors includes, amongst others, Daniel Schacter, Richard Morris, Fareneh Vargha-Khadem, and Endel Tulving. The work presented within this book will have a profound effect on the direction that future research in this topic will take. (shrink)

From Simon & Schuster and edited by Morris Weitz, 20th Century Philosophy: The Analytic Tradition is a collection of readings in the history of philosophy. The full scope and impact of Western philosophy from the Presocratics to the important thinkers of the twentieth century are presented in this original paperback series.

Numerous theories have attempted to overcome the anti-essentialist scepticism about the possibility of defining art. While significant advances have been made in this field, it seems that most modern definitions fail to successfully address the issue of the ever-changing nature of art raised by Morris Weitz, and rarely even attempt to provide an account which would be valid in more than just the modern Western context. This thesis looks at the most successful definitions currently defended, determines their strengths and (...) weaknesses, and offers a new, cultural definition which can preserve the good elements of other theories, solve or avoid their problems, and have a scope wide enough to account for art of different times and cultures. The resulting theory is a synthetic one in that it preserves the essential institutionalism of Dickie's institutional views, is inspired by the historical and functional determination of artistic phenomena present in Levinson's historicism and Beardsley's functionalism, and presents the reasons for something becoming art in a disjunctive form of Gaut's cluster account. Its strengths lie in the ability to account for the changing art-status of objects in various cultures and at various times, providing an explanation of not only what is or was art, but also how and why the concept 'art' changes historically and differs between cultures, and successfully balancing between the over-generalisations of ahistorical and universalist views, and the uninformativeness of relativism. More broadly, the cultural theory stresses the importance of treating art as a historical phenomenon embedded in particular social and cultural settings, and encourages cooperation with other disciplines such as anthropology and history of art.

An essential addition to the Stone Reader series, Question Everything is a groundbreaking collection of philosophical essays from some of our foremost thinkers and storytellers. When The Stone Reader-a landmark collection of 133 essays from the New York Times' award-winning philosophy column-first published, in 2015, the world urgently needed insight and wisdom, and for many, the book served as a bulwark of reason against the rising tide of post-fact rhetoric. Now, as disinformation continues to run rampant and our rights are (...) increasingly called into question, editors Peter Catapano and Simon Critchley contend that philosophy in the public sphere is more crucial than ever. Like The Stone Reader and its sequel, Modern Ethics in 77 Arguments, Question Everything delivers the contrarian views, sound arguments, and creative approaches to traditional opinion-writing that loyal readers of the series have come to expect. Its essays, however, are not organized by traditional categories like ethics or epistemology, but thematically by question, thirteen of them in all-the first twelve like the hours of a clock, ticking us through the tumultuous time in which these pieces were written, from late 2015 to 2021, with the last speculating into an uncertain future. The volume begins with the most fundamental of questions: What does it mean to be human? There, contemporary thinkers from Martha Nussbaum to Bernard-Henri Lévy explore the essence of who we are as a species. The next question-Is democracy possible?-interrogates our social and political ideals. While Malka Older calls into question the viability of our institutions, philosophers Gary Gutting and Alex Rosenberg reassess the meaning of patriotism. And onward, with more timeless struggles: What is happiness? Does life have meaning? Finally, it asks, Is this the end of the world as we know it? Now what? While its foundation and core consists of the work of professional scholars and philosophers, Question Everything also features a number of prominent artists and thinkers who may never appear on a philosophy syllabus, including, among others, novelist Elena Ferrante, actor Cate Blanchett, filmmaker Errol Morris, musician Sonny Rollins, and artist Ai Weiwei, all of whom offer insights shaped by decades of devotion to and practice of their crafts. Designed both for immediate gratification and long-term use, Question Everything, with an introduction by Catapano, is not only an essential addition to a much-loved series, but an act of resistance, "a product," as Catapano writes, "of the spirit of agitation and inquiry that has been integral to the human enterprise from the beginning of recorded history.".

My objective in this project is to explore the concept of moral luck as it relates to sports. I am especially interested in constitutive luck. As a foundation I draw from both Bernard Williams and Thomas Nagel’s classic handling of moral luck, generally. Within the philosophy of sport are similar explorations of this nexus by Robert Simon and David Carr that also factor into the present work. My intent is to put a new lens in front of a puzzle (...) drawn from Torbjörn Tännsjö’s well-known article ‘Is Our Admiration of Sports Heroes Facistoid?’ Specifically, the idea that we might admire an athlete who excels without having worked hard for it. If we may call this puzzle ‘the talent problem,’ the questions driving the present work are as follows: what is the relationship between moral luck and the talent problem, and can this relationship provide a prescription for morally assessing the talent problem? The thesis that this exploratory work suggests that more complex games (and... (shrink)

Richard Rorty is one of the most influential and provocative figures in contemporary intellectual life. He argues that many of philosophy's traditional concerns are redundant, and that the goal of inquiry should not be truth but human betterment. In this collection a distinguished team of scholars grapples with the implications of his writings for social and political thought. Avoiding mindless adulation or ritual denunciation, they offer careful but critical investigations of the meaning of Rorty's work for a range of important (...) issues. Topics explored include anti-foundationalism; irony and commitment; justice; liberalism and utopianism; reason and aesthetics; humanism and anti-humanism; the Holocaust; the theory of international relations; social democracy and the pragmatist tradition. Each essay is followed by a reply written for this volume by Rorty. The volume also includes a substantial essay by Rorty on 'Justice as a Larger Loyalty'. This volume is indispensable for any reader interested in Rorty's work, or in contemporary debates in social, political or ethical theory. Contributors: Molly Cochran; Daniel Conway; Matthew Festenstein; Norman Geras; John Horton; David Owen; Richard Rorty; Kate Soper; Simon Thompson. (shrink)

Why is consciousness associated with recovery of memories that are initially dependent on the hippocampal system? A hypothesis is proposed that the medial temporal lobe/hippocampal complex (MTL/H) receives as its input only information that is consciously apprehended. By a process termed “cohesion,” the MTL/H binds into a memory trace those neural elements that mediated the conscious experience so that effectively, “consciousness” is an integral part of the memory trace. It is the phenomenological records of events (Conway 1992), integrated consciousness-content (...) packets, that are recovered when memory traces are retrieved. (shrink)

A number of authors have pointed to “convergent evolution” as evidence for the central role of natural selection in shaping predictable trajectories of macroevolution. However, there are numerous conceptual and empirical difficulties that arise in broadly appealing to the frequency of homoplasy as evidence for a non-contingently constrained adaptational design space. Most important is the need to distinguish between convergent (externally constrained) and parallel (internally constrained) evolution, and to consider how the respective frequencies of these significantly different sources of homoplasy (...) affect a strong adaptationist view of life. In this paper, I critically evaluate Simon Conway Morris’s use of the homoplasy literature to support his argument for a non-contingent, counterfactually stable account of macroevolutionary pattern. In so doing, I offer a conception of parallelism which avoids the charge that it differs from convergence merely in degree and not in kind. I argue that although organisms sharing a homoplastic trait will also share varying degrees of homology, it is the underlying developmental homology with respect to the generators directly causally responsible for the homoplastic event that defines parallel evolution and non-arbitrarily distinguishes it from convergence. The notion of “screening-off” is used to distinguish the proximal generators of a homoplastic trait from its more distal genetic causes (such as a master control gene). (shrink)

Life's Solution builds a persuasive case for the predictability of evolutionary outcomes. The case rests on a remarkable compilation of examples of convergent evolution, in which two or more lineages have independently evolved similar structures and functions. The examples range from the aerodynamics of hovering moths and hummingbirds to the use of silk by spiders and some insects to capture prey. Going against the grain of Darwinian orthodoxy, this book is a must read for anyone grappling with the meaning of (...) evolution and our place in the Universe. Simon Conway Morris is the Ad Hominen Professor in the Earth Science Department at the University of Cambridge and a Fellow of St. John's College and the Royal Society. His research focuses on the study of constraints on evolution, and the historical processes that lead to the emergence of complexity, especially with respect to the construction of the major animal body parts in the Cambrian explosion.

For several decades, a debate has been waged over how to interpret the significance of fossils from the Burgess Shale and Cambrian Explosion. Stephen Jay Gould argued that if the “tape of life” was rerun, then the resulting lineages would differ radically from what we find today, implying that humans are a happy accident of evolution. Simon Conway Morris argued that if the “tape of life” was rerun, the resulting lineages would be similar to what we now (...) observe, implying that intelligence would still emerge from an evolutionary process. Recent methodological innovations in paleontological practice call into question both positions and suggest that global claims about the history of life, whether in terms of essential contingency or predictable convergence, are unwarranted.

This article considers the current state of the science–religion debate in the United Kingdom. It discusses the societies, groups, and individual scholars that shape that debate, including the dialogue between theology and physics, biology, and psychology. Attention is also given to theology's engagement with ecological issues. The article also reflects on the loss of influence of denominational Christianity within British society, and the impact both on the character of the debate and the role of the churches. Finally, some promising trajectories (...) of development for the future are outlined. (shrink)

Excerpt from Relativity The four chapters which follow are four lectures delivered before the Edinburgh Mathematical Colloquium on the subject of Relativity. As many of the audience had their chief interests in other branches of mathematical science, it was necessary to start ab initio.

If I have stimulated any of my audience (...) to pursue the matter further, I shall be amply repaid for any trouble that I have taken. I wish to express my thanks to the Edinburgh Mathematical Society for the honour that they have conferred on me in inviting me to give these lectures.

Science and the End of Ethics examines some of the most important positive and negative implications that science has for ethics. Addressing the negative implications first, author Stephen Morris discusses how contemporary science provides significant challenges to moral realism. One threat against moral realism comes from evolutionary theory, which suggests that our moral beliefs are unconnected to any facts that would make them true. Ironically, many of the same areas of science (e.g. evolutionary biology, neuroscience, psychology) that present difficulties (...) for moral realism point to a new ethical approach that focuses on achieving some of the key practical goals shared by ethicists. Chief among these is how to increase amicable behavior among people. (shrink)

Long before the viewers of Ridley Scott's Alien catch their first, fleeting glimpse of the terrifying alien, they have already made the acquaintance of the alienated human beings aboard the USCSS Nostromo. The plot of Ridley Scott's Alien is well known to science fiction buffs and film enthusiasts more generally. In fact, the human members of the crew of the Nostromo exhibit “alienation”, a condition identified by Karl Marx in the “Estranged Labor” section of his Economic and Philosophic Manuscripts of (...) 1844. So long as the capitalist mode of production remains viable and authoritative, Marx insists, workers will suffer the indignities associated with alienated labor. In the transition from Alien to Aliens, the added s makes a huge difference. Alienated from their (admittedly clueless) leadership, their cloudy mission objectives, and one another, and overly dependent on their military hardware, the Colonial Marines are no match for the coordinated attack of the alien species.
