Neurobiologist William Calvin explores the human brain, positing that the neurons in the brain operate in an accelerated version of biological evolution, evolving ideas through random variations and selections, and supports his hypothesis with numerous ca.

Error theory turns on a particular presupposition about the conceptual commitments of moral realism, namely that the moral facts posited by realists need to be categorical. True moral propositions are said to have an absolute authority in their prescriptions in the sense that an agent, regardless of her own ends, needs or desires, is categorically obligated and has reason to act in accordance with their prescriptions. But, nothing in the world has such a queer property as categoricity, and therefore we (...) ought to be suspect of the enterprise of moral discourse. Some philosophers, like Stephen Finlay, have argued that this categoricity is not a necessary feature of moral language, and in so doing hope to have shown that the error theoretic critique is thus refuted. In this article I offer a survey of the literature on this topic and then contribute independent motivations for siding with those who think moral facts need not be categorical. (shrink)

In “Justice as Fairness: Political not Metaphysical,” John Rawls suggests an approach to a public conception of justice that eschews any dependence on metaphysical conceptions of justice in favor of a political conception of justice. This means that if there is a metaphysical conception of justice that actually obtains, then Rawls’ theory would not be sensitive to it. Rawls himself admitted in Political Liberalism that “the political conception does without the truth.” Similarly, in Law of Peoples, Rawls endorses a political (...) conception of justice to govern the society of peoples that is not concerned with truth, but instead concerned with being sufficiently neutral so as to avoid conflict with any reasonable comprehensive doctrines. The odd result is that this neutrality excludes any conception of truth at all. Therefore, in times of crisis that demand incisive decision making based on scientific, economic or moral considerations, public reason will stall because it can contain no coherent conception of truth.

In "The Cerebral Code," he has solidly embedded his ideas in experimental neurophysiology and neuropharmacology, deriving from his decades in the laboratory.

Investigates the rapid evolution of the ape brain into the hominid brain, and explains why understanding our evolutionary past can help us survive an uncertain future.

This book looks back at the simpler versions of mental life in apes, Neanderthals, and our ancestors, back before our burst of creativity started 50,000 years...

Treating consciousness as awareness or attention greatly underestimates it, ignoring the temporary levels of organization associated with higher intellectual function (syntax, planning, logic, music). The tasks that require consciousness tend to be the ones that demand a lot of resources. Routine tasks can be handled on the back burner but dealing with ambiguity, groping around offline, generating creative choices, and performing precision movements may temporarily require substantial allocations of neocortex. Here I will attempt to clarify the appropriate levels of explanation (...) (ranging from quantum aspects to association cortex dynamics) and then propose a specific mechanism (consciousness as the current winner of Darwinian copying competitions in cerebral cortex) that seems capable of encompassing the higher intellectual function aspects of consciousness as well as some of the attentional aspects. It includes features such as a coding space appropriate for analogies and a supervisory Darwinian process that can bias the operation of other Darwinian processes. (shrink)

Developing countries face numerous barriers to conducting effective and efficient ethics reviews of international collaborative research. In addition to potentially overlooking important scientific and ethical considerations, inadequate or insufficiently trained ethics committees may insist on unwarranted changes to protocols that can impair a study's scientific or ethical validity. Moreover, poorly functioning review systems can impose substantial delays on the commencement of research, which needlessly undermine the development of new interventions for urgent medical needs. In response to these concerns, the Drugs (...) for Neglected Diseases Initiative, an independent nonprofit organization founded by a coalition of public sector and international organizations, developed a mechanism to facilitate more effective and efficient host country ethics review for a study of the use of fexinidazole for the treatment of late stage African Trypanosomiasis. The project involved the implementation of a novel ‘pre-review’ process of ethical oversight, conducted by an ad hoc committee of ethics committee representatives from African and European countries, in collaboration with internationally recognized scientific experts. This article examines the process and outcomes of this collaborative process. (shrink)

Plan-ahead becomes necessary for those movements which are over-and-done in less time than it takes for the feedback loop to operate. Natural selection for one of the ballistic movements (hammering, clubbing, and throwing) could evolve a plan-ahead serial buffer for hand-arm commands that would benefit the other ballistic movements as well. This same circuitry may also sequence other muscles (children learning handwriting often screw up their faces and tongues) and so novel oral-facial sequences may also benefit (as might kicking and (...) dancing). An elaborated version of the sequencer may constitute a Darwin Machine that spins scenarios, evolves sentences, and facilitates insight by offline simulation. An example is given of an evolutionary scenario from an apelike ancestor, demonstrating the transition behaviors and growth curve considerations that any such theory needs to have; this particular scenario (involving throwing improvements) also suggests an explanation for the puzzling design of the Acheulean "handaxe.".

The title is not a metaphor, though past tense might be better as this chapter is about how each of the many hundred abrupt coolings of the last several million years could have served as a pump stroke, each elevating intelligence a small increment - even though what natural selection was operating on was not intelligence per se.

An expanded version has now appeared: HOW BRAINS THINK: Evolving Intelligence, Then and Now in the Science Masters series (BasicBooks 1996 in the USA and Weidenfeld & Nicolson in the UK, various translation editions elsewhere, including China).

To fit the magnificence of this setting in Beijing’s Great Hall of the People, and the honor of giving the 2007 Sir John Crawford Memorial Lecture, it is well to have a subject of suitable proportions. I have chosen one of global size and urgent time frame: our climate crisis. We only have one future and one global climate–and now it looks as if we only have one chance to rescue our civilization from collapse and prevent a mass extinction of (...) species during the 21st century. Unless you have been keeping up with climate science for the past twenty-five years, you likely do not know how serious the matter has become. The notion that we might slowly get into serious trouble by mid-century has been conveyed by the media and understood by at least some political leaders. But that scenario depends on somehow avoiding sudden shifts in climate in the meantime, instant setbacks at a time when we lack maneuvering room. An abrupt shift in drought area occurred in 1983 and we had a near-miss of a mass extinction of Amazon species in 1999. It is easy to appreciate that one more degree of global warming will seriously reduce crop yields in the tropics, but in the words of climate scientist Claudia Tebaldi 1, “It’s the extremes, not the averages, that cause the most damage to..

Since Richard Dawkins ' The Extended Phenotype got me to thinking about copying units in the mid-1980s, I have been trying to define a cerebral code by searching for what can be successfully replicated in the brain's neural circuitry, a minimum replicable unit. I indeed found such circuitry. But to explore creativity in higher intellectual function, I wanted to see if the resulting copies could compete in a Darwinian manner, the process shaping up quality as it goes. And that forced (...) me to try and boil down a lot of evolutionary biology, attempting to abstract the features that were essential from those that merely contributed to speed or stability. This isn't the place to describe the neural outcome -- it's in The Cerebral Code and, more briefly, in the seventh chapter of my other 1996 book, How Brains Think -- but this does seem an appropriate place to review what I started calling "The Six Essentials." They seem applicable to a wide range of problems within memetics9 as the field attempts to cope with evolutionary models of information transmission. For a more. (shrink)

Long before signs of staged toolmaking appeared, Homo erectus made symmetrical tools. The handaxe is a flattened tear-drop shape, but often with edges sharpened all around. Before we assign their obsession with symmetry to an aesthetic judgment, we must consider whether it is possible that the symmetry is simply very pragmatic for one particular use in the many suggested.

Interdisciplinary collaboration figures centrally in frontier research in many fields. Participants in inter-disciplinary projects face problems they would not encounter within their own disciplines. Among those are problems of mutual understanding, of finding a language to communicate both within projects and with the scientific community and society at large, and of needing to master concepts and methods of different disciplines. We think that a concentrated research and development effort is necessary to analyze, on the one hand, cognitive conditions of successful (...) understanding, communication, and interaction and, on the other, to develop specific tools and methods that support and facilitate inter-disciplinarity both in practice and in educational projects that prepare future generations of professionals within and outside of academia. Those tools need to be developed and their cognitive efficiency measured. (shrink)

Rule of law and constitutionalist ideals are understood by many, if not most, as necessary to create a just political order. Defying the traditional division between normative and positive theoretical approaches, this book explores how political reality on the one hand, and constitutional ideals on the other, mutually inform and influence each other. Seventeen chapters from leading international scholars cover a diverse range of topics and case studies to test the hypothesis that the best normative theories, including those regarding the (...) role of constitutions, constitutionalism and the rule of law, conceive of the ideal and the real as mutually regulating.
