As Peter Niebyl has documented, one of the issues in which the Wittenberg-based physician and philosopher Daniel Sennert (1572–1637) departed from Paracelsus and his followers was the concept of disease. Paracelsus and some of his followers regarded diseases as real beings—so-called “disease-entities” (entia morbis) that can enter into the body of a living being and thereafter possess a clearly defined location in the affected organism. 1 For Sennert, such a view is a dangerous confusion between disease and its causes. According (...) to him, causes of disease can be present in an organism without actually causing a disease (Sennert 1629, p. 253). Moreover, he shares the traditional Christian doctrine .. (shrink)

Abstract This article examines the little-explored remarks on verification in Wittgenstein's notebooks during the period between 1930 and 1932. In these remarks, Wittgenstein connects a verificationist theory of meaning with the notion of logical multiplicity, understood as a space of possibilities: a proposition is verified by a fact if and only if the proposition and the fact have the same logical multiplicity. But while in his early philosophy logical multiplicities were analysed as an outcome of the formal properties of simple (...) objects and simple signs, Wittgenstein in the early 1930s connects the notion of logical multiplicity with the notion of ways of seeing. I will argue that the relevant ways of seeing are closely similar to seeing-as or aspect seeing. According to Wittgenstein's view in the early 1930s, logical multiplicities are part of our perceptual experience of propositions and facts. In this sense, the verification relation depends on how we experience propositions and facts as being surrounded by a logical space of possibilities. Strikingly, Wittgenstein's way of thinking about the verification relation offers solutions to a set of seemingly intractable problems connected with the versions of verificationism developed by members of the Vienna Circle.

This paper investigates the relationship between some corpuscularian and Aristotelian strands that run through the thought of the sixteenth-century philosopher and physician Julius Caesar Scaliger. Scaliger often uses the concepts of corpuscles, pores, and vacuum. At the same time, he also describes mixture as involving the fusion of particles into a continuous body. The paper explores how Scaliger’s combination of corpuscularian and non-corpuscularian views is shaped, in substantial aspects, by his response to the views on corpuscles and the vacuum in (...) the work of his contemporary, Girolamo Fracastoro. Fracastoro frequently appears in Scaliger’s work as an opponent against whom numerous objections are directed. However, if one follows up Scaliger’s references, it soon becomes clear that Scaliger also shares some of Fracastoro’s views. Like Scaliger, Fracastoro suggests corpuscularian explanations of phenomena such as water rising in lime while at the same time ascribing some non-corpuscularian properties to his natural minima. Like Scaliger, Fracastoro maintains that there is no vacuum devoid of bodies since places cannot exist independently of bodies (although their opinions diverge regarding how exactly the relevant dependency relation might be explicated). Finally, like Scaliger, Fracastoro connects a continuum view of mixture with a theory of natural minima. (shrink)

ABSTRACT: This article explores Wittgenstein's little known remarks on colour from his notebooks of the early 1930s. It emphasizes the importance of the notion of logical multiplicity contained in these remarks. The notion of logical multiplicity indicates that Wittgenstein, as in the years of the Tractatus, is committed to a theory of logical space in which every colour is embedded. However, logical multiplicities in his remarks of the early 1930s do not depend on an apparatus of simple objects, states of (...) affairs, and elementary propositions. I suggest that, in this period, the logical multiplicity of colour space is a matter of how we see colours.RÉSUMÉ: Cet article examine les remarques trap peu connues de Wittgenstein sur les couleurs dans ses cahiers du début des années 1930. Je souligne l'importance qu'y prend la notion de multiplicité logique, qui est le signe que Wittgenstein souscrivait alors, tout autant que dans les années du Tractatus, à une théorie de l'espace logique propre à chaque couleur. Dans ces remarques du début des années 1930, les multiplicités logiques ne dépendent toutefois pas du dispositif conceptuel constitué par les objets simples, les états de choses et les propositions élémentaires. Mon propos est de montrer que, dans cétte periode, la multiplicité logique de l'espace chromatique est relative à la manière dont nous voyons les couleurs. (shrink)

According to Wittgenstein, internal relations are such that, once their terms are given, it is unthinkable that they do not hold. In his early philosophy, the concept of internal relation plays a central role in his views on meaning. The present paper addresses the question of how Wittgenstein's views about internal relations develop during his years of transition (1930-32). In particular, it investigates the connections between the concepts of internal relation, logical multiplicity, and aspect seeing in two thematic fields: (1) (...) Wittgenstein's discussion of the relation between an expectation and what fulfils it, and (2) his discussion of the relation between a sign and an action guided by it. (shrink)

Robert M. Adams claims that Leibniz’s rehahilitation of the doctrine of incomplete entities is the most sustained etlort to integrate a theory of corporeal substances into the theory of simple substances. I discuss alternative interpretations of the theory of incomplete entities suggested by Marleen Rozemond and Pauline Phemister. Against Rozemond, I argue that the scholastic doctrine of incomplete entities is not dependent on a hylomorphic analysis of corporeal substances, and therefore can be adapted by Leibniz. Against Phemister, I claim that (...) Leibniz did not reduce the passivity of corporeal substances to modifications of passive aspects of simple substances. Against Adams, I argue that Leibniz’s theory of the incompleteness of the mind cannot be understood adequately without understanding the reasons for his assertion that matter is incomplete without minds. Composite substances are seen as requisites for the reality of the material world, and therefore cannot be eliminated from Leibniz’s metaphysics. (shrink)

This paper has two aims: In the first part it is argued, that - contrary to a predominant line of interpretation in recent literature - Wittgenstein holds no implicit (positive or negative) assumptions conceming the categorial status of objects in the Tractatus. The second part tries to explain the categorial indeterminacy of Tractarian objects as a consequence of Wittgenstein's concept of logic and his distinction between "logic" and "application of logic".
