The paper deals with selected philosophical and methodological problems concerning the building of the quantum theory of gravitation, which is expected to unify general relativity and the quantum field theory into a single consistent and comprehensive theory. It outlines the basic ontological characteristics of such a theory, its structure and the limitations set upon it by the general relativity and the quantum field theory. Models of such a theory are described as well.

A serious difficulty for theories of consciousness is to go beyond mere correlation between physical processes and experience. Currently, neural workspace and sensorimotor contingency theories are two of the most promising approaches to make any headway here. This paper explores the relation between these two sets of theories. Workspace theories build on large-scale activity within the brain. Sensorimotor theories include external processes in their explanations, stressing the sensorimotor contingencies that arise from our interaction with the environment. Despite the basic differences, (...) we argue that workspace- and sensorimotor theories are complementary rather than competitive. By combining these theories, a number of problems that hamper them individually may be overcome and their strengths combined: Workspace theories have more to offer for explaining how there can be consciousness in the first place, while sensorimotor theories are strong in making sense of the specific phenomenal character of experiences.

Hilbert's axiomatization program of physical theories met an interesting challenge when it confronted the rise of quantum mechanics in the mid-twenties. The novelty of the mathematical apparatus of the then newly born theory was to be matched only by its substantial lack of any definite physical interpretation. The early attempts at axiomatization, which are described here, reflect all the difficulty of the task faced by Jordan, Hilbert, von Neumann and others. The role of von Neumann is examined in considerable detail (...) as he can be viewed here as the most outstanding of Hilbert's heirs. Von Neumann, especially in his work devoted to the proof of the impossibility of hidden variables, not only continued Hilbert's program but pushed it to its very limits, blending axiomatic rigor and interpretative commitment.

What I call the active mind approach revolves around the claim that what is “on” a person’s mind is in an important sense brought on and held on to through the agent’s self-conscious rational activ...

Existing accounts of hypothetico-deductive confirmation are able to circumvent the classical objections, but the confirmation of conjunctions of hypotheses brings them into trouble. Therefore this paper develops a new, falsificationist account of qualitative confirmation by means of Ken Gemes ' theory of content parts. The new approach combines the hypothetico-deductive view with falsificationist and instance confirmation principles. It is considerably simpler than the previous suggestions and gives a better treatment of conjunctive hypotheses while solving the tacking problems equally well.

Software systems play an ever more important role in our lives and software engineers and their companies find themselves in a position where they are held responsible for ethical issues that may arise. In this paper, we try to disentangle ethical considerations that can be performed at the level of the software engineer from those that belong in the wider domain of business ethics. The handling of ethical problems that fall into the responsibility of the engineer has traditionally been addressed (...) by the publication of Codes of Ethics and Conduct. We argue that these Codes are barely able to provide normative orientation in software development. The main contribution of this paper is, thus, to analyze the normative features of Codes of Ethics in software engineering and to explicate how their value-based approach might prevent their usefulness from a normative perspective. Codes of Conduct cannot replace ethical deliberation because they do not and cannot offer guidance because of their underdetermined nature. This lack of orientation, we argue, triggers reactive behavior such as “cherry-picking,” “risk of indifference,” “ex-post orientation,” and the “desire to rely on gut feeling.” In the light of this, we propose to implement ethical deliberation within software development teams as a way out.

Notes on the life of Adolf Lindenbaum, a complete bibliography of his published works, and selected references to his unpublished results.

The author proposes a formalization of Hilary Putnam's proof of the thesis that time does not pass. This enables one to eliminate difficulties connected with the original formulation.

Extensionalist theories of the specious present suggest that every perceptual experience is extended in time for a short while, such that they are co-extensive in time with the time experienced in them. Thus, there can be no experience of time, unless the experience itself is extended in time. Accordingly, there must be something that unites the temporal parts of a perceptual experience into temporally extended wholes. I call this the “glue-problem for extensionalism”. In this paper I suggest three desiderata that (...) an extensionalist theory should meet in order to solve the glue-problem. I also distinguish between different versions of extensionalism, and argue that none of them can solve the glue-problem without violating at least one desideratum. (shrink)

In this encyclopedia entry I canvass the current interpretations of John Locke's concept of Real Essence and the role it plays in his philosophy.

Due to the intense selection pressure against inbreeding, humans are expected to possess psychological adaptations that regulate mate choice and avoid inbreeding. From a gene’s-eye perspective, there is little difference in the evolutionary costs between situations where an individual him/herself is participating in inbreeding and inbreeding among other close relatives. The difference is merely quantitative, as fitness can be compromised via both routes. The question is whether humans are sensitive to the direct as well as indirect costs of inbreeding. Using (...) responses from a large population-based sample (27,364 responses from 2,353 participants), we found that human motivations to avoid inbreeding closely track the theoretical costs of inbreeding as predicted by inclusive-fitness theory. Participants were asked to select in a forced choice paradigm, which of two acts of inbreeding with actual family members they would want to avoid most. We found that the estimated fitness costs explained 83.6% of participant choices. Importantly, fitness costs explained choices also when the self was not involved. We conclude that humans intuit the indirect fitness costs of mating decisions made by close family members and that psychological inbreeding avoidance mechanisms extend beyond self-regulation.

The main thesis of this monograph, and its novelty, is the attempt to read Newman's work not only as a defence of the author's life, but as a defence of individual life in general. This reading is done against the background of his profound personalism based on two foundations: truth and responsibility.

In this paper, I mainly pursue the following two goals: on the one hand, I want to show how a central Fregean insight is tried to be captured within a two-dimensional strategy. On the other hand, I want to show that, in the light of Saul Kripke’s arguments against descriptivism, this strategy is faced with a fundamental problem. I proceed in four steps: in a first step, I bring together the passages that contain a central Fregean insight as a source (...) of inspiration for a two-dimensional reconstruction and that suggest a descriptivist reading of Frege’s view. In a second step, I shortly present Kripke’s threefold argumentation against two versions of descriptivism, which is also the basis for Kripke’s view that proper names are rigid designators. In a third step, I explain the basic idea of a Frege-inspired two-dimensional strategy which is used to reconcile theories of definite descriptions with theories of rigid designation and which is sometimes characterized as ‘neo-descriptivism’. Since the two-dimensional strategy is dependent on rigidified definite descriptions, I argue, in a fourth step, that, in the light of Kripke’s epistemological and semantic arguments, the two-dimensional strategy is problematic and untenable – though it is, nevertheless, motivated by Kripke’s modal argument.

This is a defence of some kind of reality of relativistic effects, against the thesis that they are mere kinematic appearances or deceptions.
