That holobionts are units of selection squares poorly with the observation that microbes are often recruited from the environment, not passed down vertically from parent to offspring, as required for collective reproduction. The taxonomic makeup of a holobiont’s microbial community may vary over its lifetime and differ from that of conspecifics. In contrast, biochemical functions of the microbiota and contributions to host biology are more conserved, with taxonomically variable but functionally similar microbes recurring across generations and hosts. To save what (...) is of interest in holobiont thinking, we propose casting metabolic and developmental interaction patterns, rather than the taxa responsible for them, as units of selection. Such units need not directly reproduce or form parent-offspring lineages: their prior existence has created the conditions under which taxa with the genes necessary to carry out their steps have evolved in large numbers. These taxa or genes will reconstruct the original interaction patterns when favorable conditions occur. Interaction patterns will vary in ways that affect the likelihood of and circumstances under which such reconstruction occurs. Thus, they vary in fitness, and evolution by natural selection will occur at this level. It is on the persistence, reconstruction, and spread of such interaction patterns that students of holobiosis should concentrate, we suggest. This model also addresses other multi-species collectively beneficial interactions, such as biofilms or biogeochemical cycles maintaining all life. (shrink)

Das »Richtige und das Gute« (1930), das ethische Hauptwerk W. D. Ross’, enthält eine Vielzahl wichtiger moralphilosophischer Thesen und Argumente, die bis in die Gegenwart kontrovers diskutiert werden. Im Mittelpunkt steht seine pluralistische Deontologie, der zufolge sich die richtige Handlung aus einer Abwägung der in der jeweiligen Situation relevanten und unableitbaren Prima-facie-Pflichten ergibt, von denen nur ein Teil auf die Optimierung der Handlungsfolgen bezogen ist. Diese Deontologie wurde zu einem modernen Klassiker unter den normativen ethischen Theorien. Darüber hinaus stellt Ross’ (...) These, dass moralische Intuitionen eine Quelle selbstevidenten Wissens sein können, einen wichtigen Referenzpunkt in Debatten um den erkenntnistheoretischen Fundamentalismus dar. Auch für die Handlungstheorie liefert Ross einflussreiche Argumente, wenn er die Ansicht vertritt, dass Pflichten nie ein bestimmtes Motiv des Handelnden zum Gegenstand haben können. Eine zentrale Stellung nimmt für Ross die Güterlehre ein, in welcher er von vier Grundgütern, Tugend, Wissen, Lust und Gerechtigkeit, ausgeht. Wurde Ross in den ersten Jahrzehnten des 20. Jahrhunderts im damaligen Großbritannien als ein herausragender Ethiker – einer der bedeutendsten des Jahrhunderts, auf Augenhöhe mit G.E. Moore – angesehen, wandelte sich das Meinungsbild in den folgenden Jahrzehnten unter dem Einfluss besonders des Logischen Positivismus und der Philosophie Wittgensteins. In den letzten Jahrzehnten ist jedoch wieder ein wachsendes Interesse an Ross’ Ethik festzustellen. Dabei wird »Das Richtige und das Gute« bisweilen sogar mit der »Nikomachischen Ethik«, Kants »Grundlegung« und Humes »Untersuchung über die Prinzipien der Moral« verglichen. (shrink)

Human aesthetic experiences are pervasive; they are triggered by faces, art, natural scenery, foods, ideas, theories, and decision-making situations, among many sources, and seem to be a distinctive trait of our species. Our moral sense, understood as our capacity to judge events, actions, or people as good or bad, appropriate or inappropriate, also seems to be an exclusively human endowment (Ayala 2010). As part of the scientific efforts to characterize the biological foundations of our human uniqueness, recently there has been (...) interest in the brain’s underpinnings of aesthetic reactions to art on the one hand, and in the neural correlates of moral judgment and decision-making on the other (Greene and Paxton ..

The Right and the Good, a classic of twentieth-century philosophy by the eminent scholar Sir David Ross, is now presented in a new edition with a substantial introduction by Philip Stratton-Lake, a leading expert on Ross. Ross's book is the pinnacle of ethical intuitionism, which was the dominant moral theory in British philosophy for much of the nineteenth and early twentieth century. Intuitionism is now enjoying a considerable revival, and Stratton-Lake provides the context for a proper understanding of Ross's great (...) work today. (shrink)

What connexion is there between factual statements concerning God or man and moral judgments? That is the question which occasions this paper. Not long ago moral philosophers were wont to say that there is a logical gap between the two sorts of utterance to which I have just referred: that nothing follows in terms of moral value from a statement of fact, no ‘ought’ from any ‘is’. They recognised only one restriction on what may be said in terms of ‘ought’ (...) by what has been said in terms of ‘is’, namely that ‘ought’ implies ‘can’. It is manifest nonsense to say that anyone ought to do what he cannot do. But, this apart, they thought it possible without contradiction or anomaly to hold any conceivable factual belief and at the same time subscribe to any conceivable moral judgment. They would have held that it makes perfectly good sense to say, for example, ‘This is God’s will but it ought not to be done’ or ‘Men are not pigs but a good man will live like a pig’. Bizarre such judgments may be, they would have said, but nonsensical they are not. They conceived it to be their main business, as moral philosophers, to erect warning notices along the edge of the is-ought gap so that contemporary moralists would not fall headlong into it as so many of their predecessors, in less enlightened ages, had done.

It is sometimes suggested that the logic of religious language differs from other kinds of language. Or it is said that each ‘language-game’ has its own ‘logic’ and that, whatever usual language-games are played in the context of religion, there is something that could be called the ‘religious language-game’ which does not correspond to any other and, therefore, has its own peculiar logic. In either case, religious people are urged to make clear what this logic is, so that their utterances (...) may be understood and evaluated. (shrink)

At the beginning of his book, Principles of Christian Theology, John Macquarrie says that theology ‘implicitly claims to have its place in the total intellectual endeavour of mankind’. The question I want to discuss is this: in what terms, if any, can that claim be justified?

I want to put forward a certain view of the logical foundation of religious belief. It is, in a sentence, the view that religious belief is constituted by the concept of god. This view will be discussed under three headings. First, I shall explain as clearly as I can what I mean by it. Secondly, I shall indicate what seem to me to be interesting parallels, both with regard to universes of discourse in general and to religious belief in particular, (...) between my idea of a constitutive concept and Wittgenstein's ideas of a fundamental proposition and a religious ‘picture’. Thirdly, I shall try to substantiate the view I take of the logical foundation of religious belief by rebutting three conceivable objections to it: namely, that it rests on an illegitimate craving for generality, that it is at variance with common usage, and that it consigns religious belief to an intellectual ghetto.

We assess J. Baird Callicott’s attempt in Earth’s Insights to reconcile his land ethic with the “environmental ethics” of indigenous peoples. We critique the rejection of ethical pluralism that informs this attempted rapprochement. We also assess Callicott’s strategy of grounding his land ethic in a postmodern scientific world view by contrasting it with the roles of “respect” and narrative in indigenous “ethics.”.

Unlike old soldiers, the rhetoric of the great neither dies nor fades away. And so Hume's celebrated ‘is-ought’ passage still provokes debate.Hume was worried about the relation between ought statements and those supporting them: between ‘tolerence brings peace’ or ‘is God's will’, and ‘so one ought to be tolerant’. He denies the deducibility of the latter from the former, as the ‘ought’ expresses ‘a new relation or affirmation’, ‘entirely different from the others’. And this is commonly taken as saying that (...) the ought statement is ‘different’ and non-deducible, because it is no longer a ‘purely factual statement’, to wit one that makes another ordinarily testable truth claim.However, recent criticism, by W. D. Hudson and others, points out that Hume says other things seemingly inconsistent with this. In the passage, he mentions ‘ought’ and ‘virtue’ interchangeably, and ‘tolerance is virtuous’ as in the same boat as ‘one ought to be tolerant’. But, also, he treats the virtue of an action as sensibly discernible by the approbation which it evokes, and takes us to mean by a virtuous action that we will approve of it on contemplation.

The genetically-modified-organism (GMO) experience has been prominent in motivating science, industry, and regulatory communities to address the social and ethical dimensions of nanotechnology. However, there are some significant problems with the GMO-nanotech analogy. First, it overstates the likelihood of a GMO-like backlash against nanotechnology. Second, it invites misconceptions about the reasons for public engagement and social and ethical issues research as well as their appropriate roles in nanotech research, development, application, commercialization, and regulatory processes. After an explication of the standard (...) GMO-Nanotech analogy, these two problems are discussed in turn. (shrink)

One would hardly be a human being if the good of others, or of society at large, could not weigh with one as a cogent reason for doing what will promote goodness. So one has not fully learned about living like a rational and moral being unless one has learned to appreciate that one ought to do things out of regard for others, and not only out of regard for oneself. In the first place, not everything done for oneself is (...) done for reasons of prudence. That one ought to insure one's house, save for one's old age, not put all one's money into one venture, are precepts of prudence. But it is not a precept of prudence, though it may be a good precept that someone ought to undergo a dangerous operation as a long shot to restoring his health rather than linger under a disability forever after.
