Open peer commentary on the article “Circularity and the Micro-Macro-Difference” by Manfred Füllsack. Upshot: Circularity occurs as emergent from either process or context or a combination of process and context.

Upshot: Eigenform is a precondition for distinction and distinction is a precondition for eigenform. While my target article discussed eigenform and reflexivity, it could just as well have discussed distinctions and the emergence of distinctions. This theme was implicit in many of the comments. We make this circularity explicit for the sake of a deeper understanding.

The proportion of older people in the total population is increasing in most countries because of advances in medical technology and resulting longer life expectancy. The role that older people play in our communities does not reflect this. Sometimes they are reduced to mere statistics and stereotypes in economic and political discussions on the financial burdens of care for older people. I argue that we need to rebuild inclusive communities in which older people are respected as valuable members. I suggest (...) that this can be done by studying the characteristics of past communities and by learning from the work of environmental ethicists who advocate the preservation of our heritage. Nurses share with them a holistic perspective on complex issues such as ageing. They are therefore in a position to empower older people to play a role in our communities as unique individuals with integrity and wisdom. (shrink)

We prove the hereditary undecidability of the L t theories of: (1) torsion-free Hausdorff topological abelian groups; (2) locally pure Hausdorff topological abelian groups.

Here, an epidemiological model considering pro and anti-vaccination groups is proposed and analyzed. In this model, susceptible individuals can migrate between these two groups due to the influence of false and true news about safety and efficacy of vaccines. From this model, written as a set of three ordinary differential equations, analytical expressions for the disease-free steady state, the endemic steady state, and the basic reproduction number are derived. It is analytically shown that low vaccination rate and no influx to (...) the pro-vaccination group have similar impacts on the long-term amount of infected individuals. Numerical simulations are performed with parameter values of the COVID-19 pandemic to illustrate the analytical results. The possible relevance of this work is discussed from a public health perspective. (shrink)

Bruening describes his book as "an attempt to capture the spirit of the man—not his works and his life considered in isolation from each other, but the person himself as one single human being." For the most part, however, life and works are separately presented, most of the biographical data being concentrated in the first chapter. Thereafter the works are treated one by one, in largely chronological order: "Notes on Logic" ; "Notes Dictated to Moore" ; Notebooks ; Prototractatus ; (...) Tractatus ; "Lecture on Ethics" ; Blue Book ; Brown Book ; Philosophical Investigations ; Philosophische Bemerkungen ; Philosophical Grammar ; Remarks on the Foundations of Mathematics ; Lectures and Conversations on Aesthetics, Psychology and Religious Belief ; Zettel ; On Certainty. Bruening does not explain his principles of selection. The direction of his interests is suggested by the ten pages on Lectures and Conversations, not written by Wittgenstein, as compared to the mere half page devoted to On Certainty, or by the four pages on a popular lecture on ethics as compared to the single page on Philosophische Bemerkungen. Longer treatments follow the course of the work being glossed and sample its topics, save in the case of the Investigations, where remarks are grouped under these five headings: "Reflections on the Tractatus," "Language Games and Forms of Life," "The Mind-Body Problem and Private Language," "The Nature of Philosophy," and "Seeing and Seeing As." Doubtless beginning readers such as Bruening usually has in view would have found more profit and interest in the coherent development of such themes than in running comments on work after work, especially if they had been shown inside Wittgenstein’s problems and been made to sense the struggle. This seldom happens, however, and the inaccuracies are numerous and sometimes serious. A select bibliography is appended.—G.L.H. (shrink)

The principal contemporary moral views are treated under three headings: 1) Intuitionism, represented by G. E. Moore, H. A. Prichard, and W. D. Ross; 2) Emotivism, as expounded by C. L. Stevenson; and 3) Prescriptivism, R. M. Hare's view. Warnock carefully distinguishes the questions these views were designed to answer from the questions which he feels they do in fact answer. Warnock emphasizes throughout the problem of the relation between moral discourse and conduct, as well as the question of the (...) possibility of moral "argument" in the sense of giving "reasons" for a moral viewpoint. In the latter half of the volume Warnock sketches what he takes to be some of the necessary requirements for a more adequate moral theory. He discusses "Naturalism" and rejects the blanket term as misleading unless the precise view one labels "naturalistic" is spelled out. Warnock distinguishes two "anti-naturalist" views: 1) that description and evaluation are different, i.e., that evaluation is not "reducible" to description and 2) that they are logically independent. He considers 1) a platitude. He accepts 2), but rejects what might be considered a further implication of this view—that absolutely anything might be regarded as a criterion of evaluation. In conclusion Warnock suggests that it might be profitable to look for the distinctive features of moral discourse in the content rather than the form. A good introduction to critical thinking, Warnock's account raises more questions than it answers.—C. L. H. (shrink)

In view of the confusion about the use of the term ‘population’ in biology, an analysis has been made of the use of the concept of population in biology. Origin and development, logic and epistemology of the population-concept have been investigated for that purpose. It appears that several concepts of population coexist in biology. The term ‘population’ is used for all these concepts, so it is not amazing that confusion has arisen. This confusion is the more dangerous, since ‘population’ plays (...) an important part in the theory of evolution. A modus has been suggested to diminish this confusion by defining ‘population’ in a very wide sense of the term and by proposing a ‘deme’—terminology to specify the various special concepts of population.
