In most decision-making situations, there is a plethora of information potentially available to people. Deciding what information to gather and what to ignore is no small feat. How do decision makers determine in what sequence to collect information and when to stop? In two experiments, we administered a version of the German cities task developed by Gigerenzer and Goldstein (1996), in which participants had to decide which of two cities had the larger population. Decision makers were not provided with the (...) names of the cities, but they were able to collect different kinds of cues for both response alternatives (e.g., “Does this city have a university?”) before making a decision. Our experiments differed in whether participants were free to determine the number of cues they examined. We demonstrate that a novel model, using hierarchical latent mixtures and Bayesian inference (Lee & Newell, 2011) provides a more complete description of the data from both experiments than simple conventional strategies, such as the take–the–best or the Weighted Additive heuristics.

Corporate psychopathy thrives perhaps as the most significant threat to ethical corporate behaviour around the world. We argue that Human Resources Management professionals should formulate strategic solutions metaphorically by balancing what strategic military planners famously call ‘Search and Destroy’ and ‘Hearts and Minds’ counter-terrorist strategy. We argue that these military metaphors offer creative inspiration to help academics and practitioners theorise CP in richer, more reflective and more balanced and complementary ways. An appreciation of both metaphors is likely to favour the (...) use of hybrid strategies comprising SD and HM elements, which may provide the best HRM solutions to CP for the same reasons as the military now considers parallel hybrid solutions optimal for combating terrorist and guerrilla insurgency.

One of Hume's most well-known works and a masterpiece of philosophy, A Treatise of Human Nature is indubitably worth taking the time to read.

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.

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.

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.

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.
