No philosopher is needed to say where reality may be found. The fool no less than the wise man is in direct touch with real existence at every moment of his waking or dreaming life. To find reality might be a problem for timeless gods beyond the flux of nature—if timeless gods can be said to have problems—but natural creatures encounter reality at every turn. Nor need we look to the philosopher for knowledge. A division of labor having been made (...) between philosopher and scientist, it is to the scientist that we turn for most of our knowledge. Nevertheless, tasks for the philosopher remain and one of these is to make clear what knowledge is, for, to have knowledge is one thing; to know what knowledge is, is another. Science, we may safely assume, constitutes our best claim to knowledge but not all who know their science can say why it is knowledge. (shrink)

The literature of science speaks of many things in the heavens and on earth that neither the man in the street nor the scientist in his laboratory, can directly see with his eyes or touch with his fingers. Scientific hypotheses refer to atoms and genes, cosmic rays and electrostatic charges. No one can deny the importance of these hypothetical constructions; without them we could neither understand nor manage the world which we directly experience. They simplify the system of laws that (...) relate observable variables to one another. They suggest further research and enable us to predict what will be found if certain operations are carried out. The sporadic and disjointed collection of observed objects and events, and the occurrence of the unusual ones which we call illusions, are explained by correlating them with a hypothetical physical or physiological state of affairs that has order and spatio-temporal continuity.

It was with this bitter intervention from Thrasymachus, occurring halfway through the first of its ten Books, that that work begins to come urgently alive. For the remainder of Book I the Socrates of the Dialogue asks questions and raises objections, while Thrasymachus keeps urging that in fact the just become through their very justice the victims of exploitation–the suckers!

Question and quotation marks tend to proliferate in articles which ask whether Homer can provide any historical information about early Greek society. In this article ‘Homeric’ society will refer to the society which is portrayed in the Iliad and the Odyssey. ‘The World of Odysseus’ will refer to the recension of ‘Homeric’ society which appears in M. I. Finley's book of that name. Finley claims that ‘The World of Odysseus’ is a faithful account of ‘Homeric’ society and that the latter (...) is a literary portrait of a real society that existed in Greece some time during the dark ages. As a result of Finley's influential book, ‘The World of Odysseus’, or something very like it, has found its way into most of the history books generally available in the classroom. In this article I wish to reconsider ‘Homeric’ society and to question the propriety of identifying it with either ‘The World of Odysseus’ or any real society. (shrink)

At the beginning of the fifth century there was a change in the style of clothing worn by Athenian men.1 When Thucydides speaks of it,2 he first describes how the Greeks of ancient times used to carry weapons in everyday life, just as the barbarians of his own day still did. The Athenians were the first to lay weapons aside and to take up a relaxed and more luxurious way of life.

It is commonly assumed that personalization technologies used by Google for the purpose of tailoring search results for individual users create filter bubbles, which reinforce users’ political views. Surprisingly, empirical evidence for a personalization-induced filter bubble has not been forthcoming. Here, we investigate whether filter bubbles may result instead from a searcher’s choice of search queries. In the first experiment, participants rated the left-right leaning of 48 queries (search strings), 6 for each of 8 topics (abortion, benefits, climate change, sex (...) equality, immigration, nuclear family, Islam, and taxation). An independent sample of participants were then asked to select one of these queries for each of the 8 topics. With the exception of the topic of Islam, participants were significantly more likely to select a query corresponding to their own political leaning, compared to other queries, explaining between 12% and 39% of the variance. A second experiment investigated the effect of the political leaning of the same queries on the overall political leaning of Search Engine Result Pages (SERPs) in Google Search. The top six results of each SERP were rated collectively by a third group of participants, explaining 36.3% of the variance across all 48 search terms (p < .00001). That is, (1) participants in our experiments tended to select own-side search queries, and (2) using those queries tended to yield own-side search results when using the Google search engine. Our results are consistent with the notion of a self-imposed filter bubble in which query selection plays a salient role. (shrink)

Bernard Williams argues that human mortality is a good thing because living forever would necessarily be intolerably boring. His argument is often attacked for unfoundedly proposing asymmetrical requirements on the desirability of living for mortal and immortal lives. My first aim in this paper is to advance a new interpretation of Williams' argument that avoids these objections, drawing in part on some of his other writings to contextualize it. My second aim is to show how even the best version of (...) his argument only supports a somewhat weaker thesis: it may be possible for some people with certain special psychological features to enjoy an immortal life, but no one has good reason to bet on being such a person.

Why is it that despite having many of the same concerns on how ethics may be included in undergraduate medical curriculums, I write to state my concerns on Cowley’s formulation and conclusions.1I think my main problem is with an argument that starts from a position of criticising “universalising”, but offers as a substitute the idealising of another universality—“their own healthy intuitions and vocabulary”. What is it that can help in promoting an appreciation of what may be a “healthy”, as opposed (...) to an “unhealthy”, intuition? At the risk of immediately undermining my argument by indulging in psychoanalytical …. (shrink)
