Die Frequenzkurven, die die lebendige Substanz charakterisieren, können als eine statische Beschreibung oder als das Ergebnis einer Entwicklung betrachtet werden.Im ersten Falle akzeptiert man ohne weiteres die gegebenen Verteilungen und man versucht, ihnen durch mathematische Gleichungen, die keine unmittelbare Wirklich-keitsbedeutung haben, nahezukommen. Das kausale Denken wird hier ausgeschaltet oder man gibt sich wenigstens mit nur sehr groben Analogien zufrieden.Verschiedene Methoden über die Genese der Frequenzkurven werden besprochen; dabei wird gezeigt, dass die Mehrheit der Fälle auf Hypothesen beruht, die biologisch wenig (...) begründet sind. Eine Ausnahme davon macht die Theorie vonJ. C. Kapteyn, weil er den Vorgang des Wachstums in die Genese einbezieht. Seine Methode weiter ausbauend kann man sich vorstellen, dass die Genese einer Frequenzkurve in erblich homogenem Pflanzenmaterial durch Variation der Wachstumsgeschwindigkeit zustandekommt.Auf solche Weise kann man in einem Koordinatensystem mit Länge und Zeit als Koordinaten ein “Deviationsraster” konstruieren.In einem experimentell untersuchten Fall ergab die graphische Methode mit völlig ausreichender Genauigkeit die schon gefundene Frequenz.Les courbes de fréquence qui caractérisent la matière vivante, peuvent être considérées ou comme une description statique ou bien comme le produit d'un développement.Dans le premier cas on accepte les distributions obtenues et on essaie de s'en rapprocher par des équations mathématiques qui n'ont pas une réalité effective. On ne recherche plus la causalité ou alors on se contente le plus souvent d'analogies très grossières.Les auteurs traitent des diverses méthodes de la genèse des courbes de fréquence et démontrent que la plupart des cas reposent sur des hypothèses qui ont peu de fond biologique. La théorie deM. J. C. Kapteyn fait exception parcequ'il introduit le processus de croissance dans la genèse. En poursuivant plus loin dans sa méthode on peut se figurer que la genèse d'une courbe de fréquence de plantes homogènes par hérédité s'expliquerait par des variations de vitesse de croissance.De cette façon on peut construire une “grille de déviation” dans un système en prenant longueur et temps comme coordonnées.Dans un cas essayé expérimentalement ce graphique donnait avec une exactitude assez grande la distribution de fréquence déjà trouvée.

Various causes are responsible for the important absenteeism which prevails in the public sessions and committees of the legislative assemblies: the various activities to be accomplished by Representatives andSenators outside Parliament are more and more numerous and time-consuming.However, they cannot afford to neglect these since they favour the contacts indispensable for re-election. Additionally, absenteeism can be explained by the M.P.s' lack of interest for debates which they consider insignificant, either because these are too specialized, or because they concern matters largely (...) aired by the media before being submitted to Parliament, or because they cover political choices already made.Within the parliamentary institution there are means to reduce this absenteeism. It would be appropriate to reduce drastically the number of public sessions of the Assemblies and to multiply the written proceedings. It is important to make use of the existing procedures such as permanent sections, as these are better adapted than the large assemblies to the requirements of contemporary parliamentarism. Finally, it is necessary that group leaders and commission presidents should be more vigilant to absenteeism in the commissions, because it impedes correct and functional parliamentary work and can in no manner be justified.

An examination of verbal hallucinations and thought insertion as examples of "alienated self-consciousness.".

Hume's Reception in Early America: Expanded Edition brings together the original American responses to one of Britain's greatest men of letters, David Hume. Now available as a single volume paperback, this new edition includes updated further readings suggestions and dozens of additional primary sources gathered together in a completely new concluding section. From complete pamphlets and booklets, to poems, reviews, and letters, to extracts from newspapers, religious magazines and literary and political journals, this book's contents come from a wide variety (...) of sources published in colonial America and the early United States between 1758 and 1850. As well as classics by Thomas Jefferson, John Adams and Alexander Hamilton, it contains scores of unknown and hard-to-locate items, many of which have not been reprinted since their original publication. These responses are divided into four parts covering Hume's Essays; his Philosophical Writings; his History of England; and his Character and Death. Each of those parts has a separate introductory essay, and every selection is introduced by a short headnote that sets the piece in its historical context and provides bibliographical references. Packed with new insights into Hume and American thought and culture, Hume's Reception in Early America reveals the relevance and impact of Hume on American political, philosophical, historical, religious, and aesthetic debates.

This entirely new work guides the reader through the most basic systems of modal propositional logic up to systems of modal predicate with identity, dealing with both technical developments and discussing philosophical applications.

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.

Editor James Fetzer presents an analytical and historical introduction and a comprehensive bibliography together with selections of many of Carl G. Hempel's most important studies to give students and scholars an ideal opportunity to appreciate the enduring contributions of one of the most influential philosophers of science of the 20th century.

One of Hume's most well-known works and a masterpiece of philosophy, A Treatise of Human Nature is indubitably worth taking the time to read.

Throughout his career, Schelling assigns knowledge of the absolute first principle of philosophy to intellectual intuition. Schelling's doctrine of intellectual intuition raises two important questions for interpreters. First, given that his doctrine undergoes several changes before and after his identity philosophy, to what extent can he be said to “hold onto” the same “sense” of it by the 1830s, as he claims? Second, given that his doctrine of intellectual intuition restricts absolute idealism to what he calls a “science of reason”, (...) which he says cannot prove the absolute’s existence, what other doctrine does he require in order to prove this? I will answer these questions by tracing the shifts in Schelling’s doctrine of intellectual intuition from the 1790s to the 1830s and drawing out its evolving methodological role within his science of intelligibility.

The COVID-19 pandemic revealed numerous weaknesses in pandemic preparedness and response, including underfunding, inadequate surveillance, and inequitable distribution of countermeasures. To overcome these weaknesses for future pandemics, WHO released a zero draft of a pandemic treaty in February, 2023, and subsequently a revised bureau's text in May, 2023. COVID-19 made clear that pandemic prevention, preparedness, and response reflect choices and value judgements. These decisions are therefore not a purely scientific or technical exercise, but are fundamentally grounded in ethics. The latest (...) treaty draft reflects these ethical considerations by including a section entitled Guiding Principles and Approaches. Most of these principles are ethical—they establish core values that undergird the treaty. Unfortunately, the treaty draft's set of principles are numerous, overlapping, and show inadequate coherence and consistency. We propose two improvements to this section of the draft pandemic treaty. First, key guiding ethical principles should be clearer and more precise than they currently are. Second, the link between ethical principles and policy implementation should be clearly established and define boundaries on acceptable interpretation, ensuring that signatories abide by these principles.

This paper aims to show that Godel's ontological argument can be parodied in much the same kind of way in which Gaunilo parodied Anselm's Proslogion argument. The parody in this paper fails; there is a patch provided in "Reply to Gettings" (Analysis 60, 4, 2000, 363-7).

R.I.G Hughes offers the first detailed and accessible analysis of the Hilbert-space models used in quantum theory and explains why they are so successful.

This paper is a critical examination of Stephen Neale's *The Philosophical Significance of Godel's slingshot*. I am sceptical of the philosophical significance of Godel’s Slingshot (and of Slingshot arguments in general). In particular, I do not believe that Godel’s Slingshot has any interesting and important philosophical consequences for theories of facts or for referential treatments of definite descriptions. More generally, I do not believe that any Slingshot arguments have interesting and important philosophical consequences for theories of facts or for referential (...) treatments of definite descriptions. Friends of facts and referential treatments of definite descriptions can, and should, proceed with the construction of their theories, blithely ignoring the many Slingshots which now litter the landscape. (Of course, there may be other considerations which should give such theorists pause -- but those are other considerations.). (shrink)

George Boole published the pamphlet The Mathematical Analysis of Logic in 1847. He believed that logic should belong to a universal mathematics that would cover both quantitative and nonquantitative research. With his pamphlet, Boole signalled an important change in symbolic logic: in contrast with his predecessors, his thinking was exclusively extensional. Notwithstanding the innovations introduced he accepted all traditional Aristotelean syllogisms. Nevertheless, some criticisms have been raised concerning Boole’s view of Aristotelean logic as the solution of algebraic equations. In order (...) to circumvent such criticisms, we show here how Boole’s conclusions may be deduced from the axioms and inference rules proposed in his pamphlet, from which Aristotle’s deductions in Prior Analytics (including those that are completed through an impossibility) can be stated as theorems. We clarify his method for dealing with both universal and particular premises by means of his symbol v and demystify some criticisms concerning the way he expressed particular premises. Boole’s conclusions for some of those premises for which according to Aristotle there is no deduction are also discussed. The deductive system presented here has the potential to provide a new perspective on Boole’s approach to logic in The Mathematical Analysis of Logic. (shrink)
