A key topic in the work of Burghard Rieger is the notion of meaning. To explore this notion, he and his collaborators developed a most sophisticated approach combining theoretical ideas and concepts of semiotics with empirical and numerical tools of computational linguistics. In the present contribution, relations of Rieger’s achievements to some issues of interest in the physics and philosophy of complex systems will be addressed.

Placide Tempels’ Bantu Philosophy has largely been met with hostility from African philosophers. Whilst Tempels intended to show that the Bantu were not only capable of thinking, but also that they had a distinct and coherent philosophy of their own, his project seems to have achieved exactly the opposite. Temples’ project sought to expose the racism of thinkers such as Lucien Levy-Bruhl, thereby raising the African to the same status as the Westerner. However, his efforts have been rejected for a (...) number of reasons ranging from the view that it is a theory of magic, freely generalized to the Bantu, to the accusation that his project fails to speak on behalf of the oppressed Bantu and furthermore, that he is overly obsessed with finding the African difference at the cost of reason. In this paper, I seek to argue that a neglected critique of Tempels is one that has to do with the basis of his philosophical racialism. I seek to show that at the root of Bantu Philosophy is racialism grounded in the same assumptions as those made by Levy-Bruhl. I seek to argue that the categories that Tempels creates for Bantu thought do not simply seek to articulate a genuine difference from Western categories. The Bantu categories are coined as inferior, incoherent, inarticulate, illogical, and mystified. I argue that it is for reasons of philosophical racialism that Tempels urges his Western audience to overthrow their logical and articulable systems if they ever want to understand the Bantu system of thought.

We interpret the concept of determinism for a classical system as the requirement that the solution to the Cauchy problem for the equations of motion governing this system be unique. This requirement is generally believed to hold for all autonomous classical systems. Our analysis of classical electrodynamics in a world with one temporal and one spatial dimension provides counterexamples of this belief. Given the initial conditions of a particular type, the Cauchy problem may have an infinite set of solutions. Therefore, (...) random behavior of closed classical systems is indeed possible. With this finding, we give a qualitative explanation of how classical strings can split. We propose a modified path integral formulation of classical mechanics to include indeterministic systems.

Storrs McCall claims to have a novel solution to the age-old problem of the incompatibility of free will and God's omniscience. His solution is based on the thesis of the supervenience of truth on being. I argue that this thesis plays no role in solving the ancient conundrum.

If all the fundamental constants x of physics were expressed in one set of units (e.g., mks) and then used as pure numbers in one overall histogram, what shape would that histogram have? Based on some invariances that the law should reasonably obey, we show that it should have either an x−1 or an x−2 dependence. Empirical evidence consisting of the presently known constants is consistent with an x−1 law. This is independent of the system of units chosen for the (...) constants. The existence of the law suggests that the fundamental constants may have been independently and randomly chosen, at creation, from it, and hence that at the next “big bang” randomly a different set will be produced. Also, because of the law, the number 1.0 has an interesting cosmological property: it is the theoretical median of all the fundamental constants. Finally, as a practical matter, the law predicts that current methods of evaluating the fundamental constants are biased toward overly large numbers. A correction term is given for each of three kinds of noise. (shrink)

We present a structure theorem for superstable quasi-varieties without DOP. We show that every algebra in such a quasi-variety weakly decomposes as the product of an affine algebra and a combinational algebra, that is, it is bi-interpretable with a two sorted structure where one sort is an affine algebra, the other sort is a combinatorial algebra and the only non-trivial polynomials between the two sorts are certain actions of the affine sort on the combinatorial sort.

Demonstrates there are two separate (albeit remarkably similar) versions of the philosopher's engraved bookplate. Presents arguments as to which is the earlier. Speculates that the later version was produced for Hume's favorite nephew and the inheritor of his library, David Hume the Younger.

The central idea of this paper is that forming the black hole horizon is attended with the transition from the classical regime of evolution to the quantum one. We offer and justify the following criterion for discriminating between the classical and the quantum: creations and annihilations of particle-antiparticle pairs are impossible in the classical reality but possible in the quantum reality. In flat spacetime, we can switch from the classical picture of field propagation to the quantum picture by changing the (...) overall sign of the spacetime signature. To describe a self-gravitating object at the final stage of its classical evolution, we propose to use the Foldy–Wouthuysen representation of the Dirac equation in curved spacetimes, and the Gozzi classical path integral. In both approaches, maintaining the dynamics in the classical regime is controlled by supersymmetry. (shrink)
