This essay attempts to implement epistemic logic through a non-classical inference relation. Given that relation, an account of '(the individual) a knows that A' is constructed as an unfamiliar non-normal modal logic. One advantage to this approach is a new analysis of the skeptical argument.

This book is a synthesis of more than three decades of research into the concept of time and its semiotic nature. If traditional philosophy – and philosophy of time should be no exception – in the shadow of advancing biology can be said to have reached an impasse, one important reason for this, in harmony with Wittgenstein’s vision, appears to have been its lack of appropriate tools for explicating language. The present theory of time proceeds, accordingly, from the exploration of (...) temporal expressions in language as an evolutionary fact. It derives in a hypothetical, coherent feedback process of hierarchically ordered distinctions the semantics of time from its biologically dictated perceptual and cognitive-pragmatic origins. The corresponding abductive-regulative model is anchored in the assumption of biological rhythmization as the very foundation of perception and mental/physical action. Understood to originate in space and spatial perspective, time reveals itself as an instrument for temporal perspective on motion (events and situations) in a process of analysis, i.e., discontinuation of chaos made divisible and continuous by the rhythmical screen. Whereas traditional philosophy of time paid attention almost exclusively to the temporal category of tense, the biopragmatic model sees strong evidence in the perspectival nature of time for ascribing the decisive, and probably universal, role in temporal analysis to the linguistic category of aspect. Aspect may, according to the present findings, be assumed to partake already of change-of-state and cause-effect analysis without which man’s adaptation to new situations – and precondition for survival – would be inconceivable. The proposed model of space/time cognition, inspired by Hegelian dialectics, Heidegger-Gadamer’s hermeneutic circle and Peircean logic, makes Kantian a priori superfluous and liberates time from its enigmatic appearance. For the first time in temporal studies it thus appears possible to derive hypothetically linguistic expressions of time all the way from pretemporal, homogeneous continuity effected by biological rhythmization, via pretemporal metonymic (Gestalt), chunk-wise partitioning – as a general precondition for the perception and, based on primary metaphorization, the cognition of things, space and motion – to temporal analysis/discontinuation proper, primarily by aspectual perspective, and the subsequent synthesized, heterogeneous continuity of temporally ordered events. The conception of time, so disastrous for modern temporal logic, i.e., as moving object assigned extension, divisible continuity (‛linearity’) and direction, can be shown to have emerged as a result of secondary metaphorization.

Many philosophers insist that the most plausible solution to the exclusion problem is to adopt the so-called ‘autonomy approach’, which denies either upward or downward causation between mental and physical properties. But the question of whether the autonomy approach is compatible with respectable theories of causation has seldom been discussed in the literature. This paper considers two influential theories of causation, the counterfactual account and the regularity account. I argue that neither the counterfactual theory nor the regularity theory can support (...) the autonomy approach – while the counterfactual approach fails to block downward causation, the regularity approach is unable to refute upward causation.

Section 1 of this thesis investigates one issue in meta-ethics, namely, the nature of moral judgments. What are moral judgments? What does it mean by "wrong" when we assert "Killing is wrong?" Neo-sentimentalism is a meta-ethical theory which holds that the judgment that killing wrong is the judgment that it is appropriate to have a particular negative emotion towards the action. In other words, to judge that murder is wrong is to judge that we have a right reason for having (...) a negative emotion towards the behavior. In the framework of neo-sentimentalism, the concepts of wrongness consist of negative emotions. If the moral judgment is the judgment that it is appropriate to have a negative emotion towards the action, and the concept of wrongness contains a negative emotion, then the following question is what emotions are. In section 2, I endorse the bodily attitudinal theory of emotions, a view which holds that a conscious physiological reaction which induces behavior disposition and the change of facial expression and internal organs is necessary for having an emotion. This section also articulates and replies to three major objections towards the bodily attitudinal theory of emotion. (shrink)

The moral intuitions and arguments of some prominent business ethics authors regarding the ethics of monopoly are drenched with contestable economic theory. Discussions too typically ignore theoretical alternatives and debates about the nature of monopolies, their assets and liabilities. I review the theoretical debates and show why they matter to business ethics. That there may be genuine cases of rivalrous monopoly, that monopolies might in the odd circumstance prove more efficient or become advantageous in contests with labor or useful in (...) respect of a nation''s international affairs does not imply we should unwary of monopolies. However, not only the best theory to date, but also the mere fact of serious disagreement in the field suggests that there is no necessary connection between monopolies and practices such as price discrimination, price fixing, bribery, collusion, and so on. This frustrates the most pervasive and most prominent argument so far for the claim that monopolies are intrinsically unethical. (shrink)

This paper answers a philosophical challenge that emerges when we problematize the seemingly trivial "fact" that, on the one hand, through our senses we are presented with a realm that is not of our own making; while, on the other hand, various perceivers are acquainted with diverse presentations of this realm, depending on their perspective and cognitive machinery. The challenge is dubbed here the problem of presentations. The paper draws on the idea of situation-dependent properties proposed by Susanna Schellenberg. However, (...) the paper takes the notion of situation more seriously and introduces a number of basic notions borrowed from situated cognition—a cluster of ideas that have recently emerged in the philosophy of mind. These make it possible to introduce the perceiver in such a way as not to endanger the objective character of situation-dependent properties. Thought of this way, situation-dependent properties are in turn described as the building blocks of presentations. (shrink)

This thesis investigates the metaphysical nature of necessity. My study focuses primarily on the reduction of metaphysical necessity and the question of whether a necessary truth can be reductively defined. Theodore Sider develops a new reductive account of metaphysical necessity. Unfortunately, the multiple realizability problem posed by Jonathan Schaffer undermines the credibility of Sider’s account. This underlies my motivation to search for a revised Siderian account of necessity. On this basis, I propose a modified version of Sider’s account and argue (...) that analytic, natural-kind and micro-reduction truths are necessary truths if and only if they express the same states of affairs as logical truths. Since logical truths are necessary truths, analytic, natural-kind and micro-reduction truths are necessary truths as well. In this thesis, I will proceed as follows. Chapter 1 introduces Sider’s account of necessity. In particular, I focus on his analysis of the necessity of a micro-reduction truth. His analysis is largely constitutive of the notion of a metaphysical semantics and some associated notions. I reconstruct his analysis and articulate his metaphysical semantics and the associated notions. Chapter 2 presents and clarifies the multiple realizability problem of Schaffer. His critique shows that Sider’s metaphysical semantics cannot handle multiple realizability. Sider refutes this claim by arguing that the multiple realizability problem is a problem for his analysis of the necessity of a micro-reduction truth, not for his metaphysical semantics itself. This is a good starting point to propound a modified account of necessity. Chapter 3 proposes and articulates my modified analysis of the necessity of a micro-reduction, where I show that the necessity of a micro-reduction truth can be reductively defined without appeal to Sider’s metaphysical semantics. I argue that analytic, natural-kind and microreduction truths are necessary truths if and only if they express the same states of affairs as logical truths. Logical truths are necessary and so are they. After that, I consider a potential objection to my modified account and attempt to respond to it. (shrink)

Feminist philosophers of technoscience have long argued that it is vital that we question biomedical and scientific claims to an immaterial and disembodied objectivity, and also, more specifically, that we disable the conception of medical visualising technologies as neutral or transparent conduits to the “fact” of the body. In this paper we suggest that corporeal feminism is well situated to provide such a critique. Feminist phenomenologists over the past decade have theorised embodiment in a number of critical ways, many deriving (...) concepts from the work of Merleau-Ponty, and emphasising the pliability and diversity of our body images and corporeal schematics. Others such as Elizabeth Wilson, Cathy Waldby and Drew Leder have considered the interdependence of our inner biology or viscerality with the socio-cultural inscriptions of embodiment. In this paper, these adaptations of phenomenology, and their account of the specificity and depth of embodied being, will be discussed and applied to the discourse of biomedicine and the apparatus of magnetic resonance imaging (MRI).

This article is an ethnographic account of the speculative thought of Jane Roberts, a spirit medium or “channel,” important in New Age religion for the books that she dictated at the behest of a personality named “Seth.” At first, she tried to understand her strange subjectivity in psychiatric terms, then went on to elaborate metaphysical concepts to account for it. The author argues that understanding Roberts's concepts in social historical terms risks obscuring their meaning and that comparing them with the (...) related concepts of a credentialed philosopher, in this case Gilles Deleuze, is a more effective way of approaching them. The latter sort of interpretation entails another risk, however, which is that concepts like those of Roberts may get taken for mere illustrations of the arguments made by academic philosophers, whereas marginal thinking of Roberts's kind can form sophisticated bodies of thought on their own. Roberts developed concepts of consciousness and the person that exceed, in ways that this article specifies, anything that Deleuze's work can say about them and thus cast his own arguments in an unanticipated light. This essay's main point is that uncredentialed, marginal thinkers like Roberts should be considered proper objects of both anthropological and philosophical study and should be taken seriously for what they can teach us.
