Logic is usually thought to concern itself only with features that sentences and arguments possess in virtue of their logical structures or forms. The logical form of a sentence or argument is determined by its syntactic or semantic structure and by the placement of certain expressions called “logical constants.”[1] Thus, for example, the sentences Every boy loves some girl. and Some boy loves every girl. are thought to differ in logical form, even though they share a common syntactic and semantic (...) structure, because they differ in the placement of the logical constants “every” and “some”. By contrast, the sentences Every girl loves some boy. and Every boy loves some girl. are thought to have the same logical form, because “girl” and “boy” are not logical constants. Thus, in order to settle questions about logical form, and ultimately about which arguments are logically valid and which sentences logically true, we must distinguish the “logical constants” of a language from its nonlogical expressions.

Thomas Aquinas and Hervaeus Natalis share a correlational theory of intentionality. When I cognize a thing, I am in a real relation with the thing cognized and at the same time the thing is in a relation of reason with me. Hervaeus coins the term “intentionality” to designate precisely this relation of reason. First and second intentionality express two stages of this relation. First intentionality refers to the relation that a thing has to the mind, while second intentionality indicates the (...) relation that a thing qua cognized has to the mind. Thus, first intentionality involves direct cognition, while second intentionality reflexive cognition. This theory of intentionality has two purposes: first, to de-psychologize the cognitive process and second, to allow the application of Aristotle’s table of categories to the sphere of the mental. Through his detailed analysis of the relation of intentionality, Hervaeus clarifies some of Thomas’s obscurer points, but at the same time he has to solve a delicate problem of circularity entailed by the notion of intentionality as a relation of reason.

This paper indicates how continental philosophy may contribute to a diagnostics of contemporary life sciences research, as part of a “diagnostics of the present”. First, I describe various options for an oblique reading of emerging scientific discourse, bent on uncovering the basic “philosophemes” of science. Subsequently, I outline a number of radical transformations occurring both at the object-pole and at the subject-pole of the current knowledge relationship, namely the technification of the object and the anonymisation or collectivisation of the subject, (...) under the sway of automation, ICT and big machines. Finally, I further elaborate the specificity of the oblique perspective with the help of Lacan’s theorem of the four discourses. Philosophical reflections on contemporary life sciences concur neither with a Master’s discourse, nor with university discourse, nor with what Lacan refers to as hysterical discourse, but rather with the discourse of the analyst, listening with evenly-poised attention to the scientific files in order to bring to the fore the cupido sciendi which both inspires and disrupts contemporary life sciences discourse.

This monograph contributes to the scientific misconduct debate from an oblique perspective, by analysing seven novels devoted to this issue, namely: Arrowsmith by Sinclair Lewis (1925), The affair by C.P. Snow (1960), Cantor’s Dilemma by Carl Djerassi (1989), Perlmann’s Silence by Pascal Mercier (1995), Intuition by Allegra Goodman (2006), Solar by Ian McEwan (2010) and Derailment by Diederik Stapel (2012). Scientific misconduct, i.e. fabrication, falsification, plagiarism, but also other questionable research practices, have become a focus of concern for academic communities (...) worldwide, but also for managers, funders and publishers of research. The aforementioned novels offer intriguing windows into integrity challenges emerging in contemporary research practices. They are analysed from a continental philosophical perspective, providing a stage where various voices, positions and modes of discourse are mutually exposed to one another, so that they critically address and question one another. They force us to start from the admission that we do not really know what misconduct is. Subsequently, by providing case histories of misconduct, they address integrity challenges not only in terms of individual deviance but also in terms of systemic crisis, due to current transformations in the ways in which knowledge is produced. Rather than functioning as moral vignettes, the author argues that misconduct novels challenge us to reconsider some of the basic conceptual building blocks of integrity discourse. (shrink)

This essay explores some of the central aspects of Aquinas's account of mental representation, focusing in particular on his views about the intentionality of concepts (or intelligible species). It begins by demonstrating the need for a new interpretation of his account, showing in particular that the standard interpretations all face insurmountable textual difficulties. It then develops the needed alternative and explains how it avoids the sorts of problems plaguing the standard interpretations. Finally, it draws out the implications of this interpretation (...) with the aim of correcting some persistent misunderstandings of the connection between Aquinas's views and those developed by contemporary philosophers of mind.

The author contends that the Objectivist epistemology has lacked a viable model of propositional knowledge for nearly fifty years, due to neglect of Rand's unit-perspective view of concepts. This pioneering insight, he says, not only is an essential building block of her concept theory, but also welds together the three levels of logical theory and provides the clearest X-ray picture of our multilayered conceptual knowledge. Using the unit-perspective to expand Rand's theory of concepts, the author then devises a theory of (...) the proposition, giving considerable attention to axioms and statements about nonexistent subjects.

“The problem of universals” in general is a historically variable bundle of several closely related, yet in different conceptual frameworks rather differently articulated metaphysical, logical, and epistemological questions, ultimately all connected to the issue of how universal cognition of singular things is possible. How do we know, for example, that the Pythagorean theorem holds universally, for all possible right triangles? Indeed, how can we have any awareness of a potential infinity of all possible right triangles, given that we could only (...) see a finite number of actual ones? How can we universally indicate all possible right triangles with the phrase ‘right triangle’? Is there something common to them all signified by this phrase? If so, what is it, and how is it related to the particular right triangles? The medieval problem of universals is a logical, and historical, continuation of the ancient problem generated by Plato's (428-348 B.C.) theory answering such a bundle of questions, namely, his theory of Ideas or Forms.

La “relación” en Tomás de Aquino es una de las “categorías” aristotélicas que representan “accidentes”. No obstante, tal compromiso metafísico conlleva algunas dificultades ya que el esquema “sustancia”-“accidentes” no deja lugar a la idea de un “término medio” entre dos cosas. En este artículo presento algunas tensiones entre la sistematización de la “relación” como categoría en Tomás de Aquino y su posición sobre el “estatus” de los predicamentos en general. Para ello analizo primero la deducción de las categorías tal como (...) es presentada por el autor para luego abordar la “relación” de modo sistemático. En esta exposición argumento que Tomás tiene severas dificultades para asignarle un “fundamento accidental propio” distinto al de los otros predicamentos que le permita considerarla una de las “categorías”.
