Bocheński's Formalization of Summa Theologiae (Ia,75,6) Reconsidered

I investigate Bocheński's first-order logic formalization of the argument for the incorruptibility of the human soul given by Aquinas in Summa Theologiae (Ia,75,6). I suggest a slightly different axiomatization that reflect better Aquinas' informal argument. Along the way, I also fix a mistake in Bocheński's derivation that the human soul is not corruptible per se.     

Perspectivity,Intersubjectivity, Normativity: On Malpas’s Place and Experience

ABSTRACT

The publication of the revised edition of Jeff Malpas’s Place and Experience in 2018 gives the opportunity to reconsider this book (originally published in 1999) and the debates that it originally sparked. In this article, I focus on Malpas’s characterization of space as subjective, allocentric, and objective and I approach them in conjunction with other notions and considerations that, I suggest, are useful to expand and complement Malpas’s central theses. I approach the concept of subjective space in conjunction with the notion of coenaesthesis and with Heidegger’s notion of mineness (Jemeinigkeit); the concept of allocentric space by addressing Malpas’s critique of Nagel’s notion of detachment; and the concept of objective space through a discussion of the issue of perspective in light of Merleau-Ponty’s critique of Leibniz’s notion of ‘géométral’ (geometrized projection). These analyses pave the way for a discussion of some possible normative implications of the conception of place and subjectivity that emerges from Malpas’s Place and Experience against the background of Heidegger’s thought, and particularly in relation to Heidegger’s notion of dwelling (Wohnen).     

Group decision as a twice multicriteria optimum problem

This paper studies the problem of aggregation of preferences, preserving the multicriteria nature of the individual decision process. The resulting group decision problem is in effect a twice multicriteria optimum problem. We give a structural theory for the efficient set of this optimum problem. Moreover, on the basis of this theory we study the relationships between optimality, consensus and evaluation. We confirm the pathological nature of aggregation of preferences, but in a new setting and with a different meaning.
