MATERIALISTS claim that in principle mentality could be accounted for entirely by properties of matter. They must, of course, clarify, as far as possible, the precise scope of the concept "properties of matter." According to materialists there exists only one type of "substance" in the universe, namely matter. Sophisticated experimental and theoretical analyses have led contemporary physicists to interpret known material entities as being composed of two classes of elementary particles, namely quarks and leptons and constituents of interaction fields that (...) mediate interactions between some or all of the elementary particles and which comprise photons, gluons, intermediate bosons and gravitons. For instance, protons and neutrons are composed--by hypothesis--of quarks, while electrons are probably the most familiar leptons. Whether any analyzed and postulated elementary particles and constituents of interaction fields are "ultimate" components of matter can never be known. It remains always possible that more basic subcomponents of known components will be discovered. This has happened repeatedly throughout the history of physics. Hence, what physicists understand by the "physical properties" of the basic components of matter must always remain expressed in terms of usually intricate hypothetico-deductive theories which are tentative and fallible. Contemporary relativistic quantum mechanics of elementary particles and of interaction fields provide typical examples of such hypothetico-deductive theories relating to present known basic components of matter.

SummaryExtremism in the environment‐versus innateness controversy in the behavioural sciences and in human sociobiology is being examined. Genetic effects can be severely modified or overruled by environmental factors, but may, nevertheless, be important. Dawkins' view that we are survival machines programmed to subserve selfish genes seems untenable and is a root of racialism. It is also argued that morality is compatible with mixed genetic and environmental control of brains via existing biological machinery.

The Four-Colour Theorem (4CT) proof, presented to the mathematical community in a pair of papers by Appel and Haken in the late 1970's, provoked a series of philosophical debates. Many conceptual points of these disputes still require some elucidation. After a brief presentation of the main ideas of Appel and Haken’s procedure for the proof and a reconstruction of Thomas Tymoczko’s argument for the novelty of 4CT’s proof, we shall formulate some questions regarding the connections between the points raised by (...) Tymoczko and some Wittgensteinian topics in the philosophy of mathematics such as the importance of the surveyability as a criterion for distinguishing mathematical proofs from empirical experiments. Our aim is to show that the “characteristic Wittgensteinian invention” (Mühlhölzer 2006) – the strong distinction between proofs and experiments – can shed some light in the conceptual confusions surrounding the Four-Colour Theorem.

The theory of pramonotheism is an important part of the theological conception of religion. Its founder is an Austrian theologian of the twentieth century. W. Schmidt. However, this theory was advanced and developed even before Schmidt in the Orthodox thought of the twentieth century, in which it was called "the doctrine of the original monotheism." The theory of pramonotheism was developed in the field of basic theology with the task of comprehending the emergence and evolution of religion in the paradigm (...) of Christian monotheism, as well as to refute views of religion only in the context of the natural laws of human consciousness and social life.

This edition, the first modern one in English, introduces undergraduates and more advanced students to the therapeutic possibilities of Seneca's Stoic philosophy. The short treatises De otio and De brevitate vitae balance each other by representing different but complementary aspects of Senecan philosophy: in De otio, one's duty to the 'active' life, in De brevitate vitae, one's duty to oneself in reclaiming life from the impositions made upon the self. The provocative Senecan message is to promote introspection in life, and (...) to suggest the benefits of an inner existence of the personal. In addition to its literary and linguistic emphasis, this edition tries to advertize the means by which Seneca conveys the attractions of his therapeutic 'philosophy'. (shrink)

At Phaedo 59b Echecrates asks Phaedo who was present on the day when Socrates drank the hemlock in prison. Various Athenians are named , then various foreigners , but when Echecrates subsequently asks if two other foreigners, Aristippus and Cleombrotus, were present, Phaedo replies that they were said to be in Aegina . After this fleeting reference to Cleombrotus, Plato does not mention him again in the Phaedo or any other dialogue; and yet in later antiquity a certain Cleombrotus of (...) Ambracia rose to fame in connection with the Phaedo. Callimachus is our earliest source for the anecdote which immortalized the Ambracian : Επας ‘Ἥλιε αρε’ Κλεμβρτος μβρακιτης λατ' φ' Ψηλο τεεος ες δην, ζιον οδν δν θαντου κακν, λλ Πλτωνος ν τ περ Ψυς γρμμ' ναλεζμενος.
