This thesis addresses three challenges posed by intentionality - the ability of our mental states and language to be about something - to a logician: an apparent reference to non-existent objects, intentional indeterminacy and the failure of substitutivity of coextensive terms in an intentional context. Since intentionality plays an important role in our everyday reasoning, a proper formal account of it is highly desirable, yet it requires a departure from classical logic. One can modify classical logic and adapt the formal (...) apparatus to account for the aforementioned problems (Graham Priest’s logic for intentionality serves as an example of such an approach in this work) or one can make an even more radical shift and seek for inspiration in a different logical tradition like the terminist logic developed in the Late Middle Ages by figures like William of Ockham or John Buridan. The second path is explored here as a modest attempt to show that once we abandon the bias against the history of logic as irrelevant, we can actually get access to firm logical solutions inaccessible from a classical perspective, while still practising logic proper.

IntroductionIn this paper I examine William Ockham's theory of judgment — in particular, his account of the nature and ontological Status of its objects. ‘Judgment’ (Latiniudicio)is the expression Ockham and other medieval thinkers use to refer to a certain subset of what philosophers nowadays call ‘propositional attitudes’. Judgments include all and only those mental states in which a subject not only entertains a given propositional content, but also takes some positive stance with respect to its truth. For Ockham, therefore, as (...) for other medievals, a judgment is a type of mental State that includes attitudes such as belief, knowledge, opinion, doubt, faith, and so on. (shrink)

This article develops a new perspective on theism that makes the simple juxtaposition of theism and atheism problematic, and helps bridge philosophy of religion and the empirical study of religious phenomena. The basic idea is developed inspired by Terrence Deacon's book Incomplete Nature and its description of “ententional” phenomena, together with some ideas from the cognitive science of religion, especially those related to agency and “theological correctness.” It is argued that God should not be understood as a “homunculus” that stops (...) an otherwise infinite regress of arguments.

In line with his theory of secularization according to which all significant concepts of the modern theory of the state are secularized theological concepts, Carl Schmitt argues in Constitutional Theory that people’s (Volk) constitution-making power in modern democracy is analogical to God’s potestas constituens in medieval theology. It is also undoubtedly possible to find a resemblance between Schmitt’s constitution-making power and God’s power as it is described in medieval theology. In the same sense as the constitution-making power is absolutely free (...) from all normative ties, God’s potestas constituens, or rather, God’s potentia absoluta is free from such ties. Yet, unlike the Schmittian constitution-making power, God’s potentia absoluta was not, in medieval theology, originally intended as a description of some form of divine action: the absolute power of God referred to the total possibilities initially open to God. However, when the canonists started to employ the term potentia absoluta in their speculations concerning the papal plenitude of power (plenitude potestatis) by the end of the thirteenth century, they used it in a different sense than the theologians previously. According to certain canonists, the pope, by his potentia absoluta, could grant de facto dispensations from divine and ecclesiastical laws. Later on, this notion became a theological notion as well, but given its origin in juridical discourse, the constitution-making power, rather than being a secularized theological notion, is a theologized juristic notion.

The thesis tries to define and explain the rudiments of a 'nonphilosophical' or 'non-decisional' theory of materialism on the basis of a theoretical framework provided by the 'non-philosophy' of Francois Laruelle. Neither anti-philosophical nor anti-materialist in character, non-materialism tries to construct a rigorously transcendental theory of matter by using certain instances of philosophical materialism as its source material. The materialist decision to identify the real with matter is seen to retain a structural isomorphy with the phenomenological decision to identify the (...) real with the phenomenon. Both decisions are shown to operate on the basis of a methodological idealism; materialism on account of its confusion of matter and concept; phenomenology by virtue of its confusion of phenomenon and logos. By dissolving the respectively 'materiological' and 'phenomenological' amlphibolies which are the result of the failure to effect a rigorously transcendental separation between matter and concept on the one hand; and between phenomenon and logos on the other, non-materialist theory proposes to mobilise the non-hybrid or non-decisional concepts of a 'matter-without-concept' and of a 'phenomenon-without-logos' in order to effect a unified but non-unitary theory of phenomenology and materialism. The result is a materialisation of thinking that operates according to matter's foreclosure to decision. That is to say, a transcendental theory of the phenomenon that licenses limitless phenomenological plasticity, unconstrained by the apparatus of eidetic intuition or any horizon of apophantic disclosure; yet one which is simultaneously a transcendental theory of matter, uncontaminated by the bounds of empirical perception and free of all phenomenological circumscription.

To understand pre-Fregean theories of judgment and proposition, such as those found in Locke and the Port-Royal logic, it is important to distinguish between propositions in the modern sense and propositions in the pre-Fregean sense. By making this distinction it becomes clear that these pre-Fregean theories cannot be meant to solve the propositional attitude problem. Notwithstanding this fact, Locke and Arnauld are able to make a distinction between asserted and unasserted propositions (in their sense). The way Locke makes this distinction (...) turns out to be very different from the way it is made by Arnauld. (shrink)

In this paper I examine William Ockham’s theory of judgment and, in particular, his account of the nature and ontological status of its objects. Commentators, both past and present, habitually interpret Ockham as defending a kind of anti-realism about objects of judgment. My aim in this paper is two-fold. The first is to show that the traditional interpretation rests on a failure to appreciate the ways in which Ockham’s theory of judgment changes over the course of his career. The second, (...) and larger, aim is to show that careful attention to these changes in Ockham’s account (and to the motivations for them) sheds new light on broader developments in his philosophy of mind—specifically, on his views about the nature of concepts and on his account of the nature and structure of intentionality itself.

Philosophers today have largely given up on the project of categorizing being. Aristotle’s ten categories now strike us as quaint, and no attempt to improve on that effort meets with much interest. Still, no one supposes that reality is smoothly distributed over space. The world at large comes in chunks, and there remains a widespread intuition, even among philosophers, that some of these chunks have a special sort of unity and persistence. These, we tend to suppose, are most truly agents (...) and subjects, and are what exist in the most proper sense of the term. We believe, in other words, in substances. (shrink)

The central recommendation of this article is that philosophers trained in the analytic tradition ought to add the sensibilities and skills of the historian to their methodological toolkit. The value of an historical approach to strictly philosophical matters is illustrated by a case study focussing on the medieval origin of conceivability arguments and contemporary views of modality. It is shown that common metaphilosophical views about the nature of the philosophical enterprise as well as certain inference patterns found in thinkers from (...) Descartes to Chalmers have their origin in the theological concerns of the Scholastics. Since these assumptions and inference patterns are difficult to motivate when shorn of their original theological context, the upshot is that much post-Cartesian philosophy is cast in an altogether unfamiliar, and probably unwelcome, light. The methodological point, however, is that this philosophical gain is born of acquaintance with the history of ideas. (shrink)
