The work of Professor Jaeger on the Aristotelian metaphysics, and its modification by the late Hans von Arnim, have raised many new points of the greatest interest, and may, I hope, be considered as having opened up a large and fascinating new field for discussion rather than as having closed the matter. It is a subject which must be considered as a whole. There would be little profit in writing short notes on isolated points in the arguments of the two (...) scholars. Anyone who, possessed of some previous acquaintance with the Aristotelian corpus, reads their work is inevitably stimulated to return to Aristotle with his mind full of fresh ideas. If after a re-examination of the texts he feels he has a different story to tell, he must tell it for himself. That is my excuse for an account which must include much which was always known and much which has arisen out of the work of Jaeger and von Arnim. My conclusions are not the same as theirs, and the argument must stand or fall as a consistent whole. (shrink)

A square tabular array was introduced by R. C. Punnett in (1907) to visualize systematically and economically the combination of gametes to make genotypes according to Mendel’s theory. This mode of representation evolved and rapidly became standardized as the canonical way of representing like problems in genetics. Its advantages over other contemporary methods are discussed, as are ways in which it evolved to increase its power and efficiency, and responded to changing theoretical perspectives. It provided a natural visual decomposition of (...) a complex problem into a number of inter-related stages. This explains its computational and conceptual power, for one could simply “read off” answers to a wide variety of questions simply from the “right” visual representation of the problem, and represent multiple problems, and multiple layers of problems in the same diagram. I relate it to prior work on the evolution of Weismann diagrams by Griesemer and Wimsatt (What Philosophy of Biology Is, Martinus-Nijhoff, the Hague, 1989), and discuss a crucial change in how it was interpreted that midwifed its success.

Studie van de oud-direkteur van het Humanistisch Verbond over een verantwoorde humanistische levenshouding, waarin ook de religieuze dimensie een plaats heeft.

Three famous sophists are referred to together in the Apology of Sokrates as still practising their enviably lucrative itinerant profession in 399 B.C. (not, by implication, in Athens): Gorgias of Leontinoi, Prodikos of Keos and Hippias of Elis. The last of these was the least well known to the Athenian demos, having practised mainly in Dorian cities. There is no extant reference to him in Old Comedy, but we can assume that he was sufficiently famous - especially for his fees (...) (possibly the highest charged by any sophist) - to justify his inclusion as the third of this 'triad'; cf. the triad Protagoras - Hippias - Prodikos in the Protagoras, considered further below. Gorgias was by now a grand old man of about ninety (with more than a decade of active life still ahead of him), the last survivor of the first generation of fee-taking educators, associated first and foremost in the popular mind with the suspect arts of political and forensic persuasion. Prodikos and Hippias were probably in their sixties. (shrink)
