Crane envisions the speculative conjecture that intelligent civilizations might want and be able to produce black holes in the very far future. He implicitly suggests two main purposes of this enterprise: (i) energy production and (ii) universe production. We discuss those two options. The commentary is obviously highly speculative and should be read accordingly.

Philosophy lacks criteria to evaluate its philosophical theories. To fill this gap, this essay introduces nine criteria to compare worldviews, classified in three broad categories: objective criteria (objective consistency, scientificity, scope), subjective criteria (subjective consistency, personal utility, emotionality), and intersubjective criteria (intersubjective consistency, collective utility, narrativity). The essay first defines what a worldview is and exposes the heuristic used in the quest for criteria. After describing each criterion individually, it shows what happens when each of them is violated. From the (...) criteria, it derives assessment tests to compare and improve different worldviews. These include the is-ought, ought-act, and is-act first-order tests; the critical and dialectical second-order tests; the mixed-questions and first-second-order third-order tests; and the we-I, we-it, and it-I tests. The essay then applies these criteria and tests to a concrete example, comparing the Flying Spaghetti Monster deity with Intelligent Design. For another application, it draws more general fruitful suggestions for the dialogue between science and religion. (shrink)

Jan Greben criticized fine-tuning by taking seriously the idea that “nature is quantum mechanical”. I argue that this quantum view is limited, and that fine-tuning is real, in the sense that our current physical models require fine-tuning. Second, I examine and clarify many difficult and fundamental issues raised by Rüdiger Vaas’ comments on Cosmological Artificial Selection.

The Principia Cybernetica Project was created to develop an integrated philosophy or world view, based on the theories of evolution, self-organization, systems and cybernetics. Its conceptual network has been implemented as an extensive website. The present paper reviews the assumptions behind the project, focusing on its rationale, its philosophical presuppositions, and its concrete methodology for computer-supported collaborative development. Principia Cybernetica starts from a process ontology, where a sequence of elementary actions produces ever more complex forms of organization through the mechanism (...) of variation and selection, and metasystem transition. Its epistemology is constructivist and evolutionary: models are constructed by subjects for their own purposes, but undergo selection by the environment. Its ethics takes fitness and the continuation of evolution as the basic value, and derives more concrete guidelines from this implicit purpose. Together, these postulates and their implications provide answers to a range of age-old philosophical questions. (shrink)

Testing the validity of knowledge requires formal expression of that knowledge. Formality of an expression is defined as the invariance, under changes of context, of the expression's meaning, i.e. the distinction which the expression represents. This encompasses both mathematical formalism and operational determination. The main advantages of formal expression are storability, universal communicability, and testability. They provide a selective edge in the Darwinian competition between ideas. However, formality can never be complete, as the context cannot be eliminated. Primitive terms, observation (...) set-ups, and background conditions are inescapable parts of formal or operational definitions, that all refer to a context beyond the formal system. Heisenberg's Uncertainty Principle and Gödel's Theorem provide special cases of this more universal limitation principle. Context-dependent expressions, on the other hand, have the benefit of being more flexible, intuitive and direct, and putting less strain on memory. It is concluded that formality is not an absolute property, but a context-dependent one: different people will apply different amounts of formality in different situations or for different purposes. Some recent computational and empirical studies of formality and contexts illustrate the emerging scientific investigation of this dependence. (shrink)

My thesis situates itself within the field of the Philosophy of Worldviews. Specifically, it aims to address the normative question of what the task should be of such a philosophy when faced with the problem of conflicting beliefs between religious worldviews. To answer this question, I turn to the procedure of aporetical analysis, in short, aporetics. Firstly, aporetics offers a distinct method of consistency restoration within inconsistent sets on the basis of thesis rejection and thesis modification. Secondly, aporetics leads to (...) an understanding of the availability of aporetic exits on the basis of epistemic criteria. On the one hand, this leads us to opt for an orientational monism/pluralism, which steers the middle course between the epistemic stances of exclusivism and pluralism. On the other hand, it allows us to identify epistemic criteria for worldview acquisition on the basis of three distinct superclasses. These superclasses can be derived from Jürgen Habermas' validity claims, and applied to the self-understanding of contemporary theories of religion. (shrink)

The term “evolution” is often used in the administrative sciences to designate dynamic processes of change in general. In biology, evolution has a very specific meaning, namely the application of a generative variation-selective retention scheme to change. Applying this to the administrative sciences is more exacting: describing what the variation consists of, how replication of the generated variation occurs and delineating the population from which the selection is made are far from easy. While it is the intention of this special (...) issue as a whole to provide some empirical examples of evolutionary change in the public and private sectors, this introduction will lay out the main lines of thought in what is often referred to as universal Darwinism and what this means in the administrative sciences. Key concepts here are generative variation, selective retention, and selective institutional environment. According to the authors, the Darwinian scheme of evolutionary theory focuses on how new ideas or concepts arise, how they propagate and influence wider actor thinking and on how the institutional environment in which they operate affects their differential survival. This evolutionary process is an interplay between actors and replicators (sounds, images, and in this context mostly words) in which it cannot be said in advance which one is fooling the other.

We have demonstrated, using the Cantor dust method, that the statistical distribution of appearance and disappearance of rodents species (Arvicolid rodent radiation in Europe) follows power laws strengthening the evidence for a fractal structure set. Self-similar laws have been used as model for the description of a huge number of biological systems. With Nottale we have shown that log-periodic behaviors of acceleration or deceleration can be applied to branching macroevolution, to the time sequences of major evolutionary leaps (global life tree, (...) sauropod and theropod dinosaurs postural structures, North American fossil equids, rodents, primates and echinoderms clades and human ontogeny). The Scale-Relativity Theory has others biological applications from linear with fractal behavior to non-linear and from classical mechanics to quantum mechanics. (shrink)
