Over the past few decades there has been a rebellion brewing in the world of Parmenides scholarship. Most of the things you probably think you know about the man have come under serious and sustained attack. No longer is it safe to accept on trust the view—which G. E. L. Owen so forcefully defended in his 1960 paper “Eleatic Questions”—that according to Parmenides there exists only one thing, ungenerated, indestructible, unchanging, indivisible, and spherical. Nor is it safe to assume (...) that he had no real commitment to empirical theorizing, and sought only to demolish the cosmological tradition that was initiated and developed by his Ionian predecessors Thales, Anaximander, and Anaximenes.

This Element is on new developments in the psychology of reasoning that raise or address philosophical questions. In traditional studies in the psychology of reasoning, the focus was on inference from arbitrary assumptions and not at all from beliefs, and classical binary logic was presupposed as the only standard for human reasoning. But recently a new Bayesian paradigm has emerged in the discipline. This views ordinary human reasoning as mostly inferring probabilistic conclusions from degrees of beliefs, or from hypothetical premises (...) relevant to a purpose at hand, and as often about revising or updating degrees of belief. This Element also covers new formulations of dual-process theories of the mind, stating that there are two types of mental processing, one rapid and intuitive and shared with other animals, and the other slow and reflective and more characteristic of human beings. The final topic covered is the new developments and rationality. (shrink)

The two main psychological theories of the ordinary conditional were designed to account for inferences made from assumptions, but few premises in everyday life can be simply assumed true. Useful premises usually have a probability that is less than certainty. But what is the probability of the ordinary conditional and how is it determined? We argue that people use a two stage Ramsey test that we specify to make probability judgements about indicative conditionals in natural language, and we describe experiments (...) that support this conclusion. Our account can explain why most people give the conditional probability as the probability of the conditional, but also why some give the conjunctive probability. We discuss how our psychological work is related to the analysis of ordinary indicative conditionals in philosophical logic. (shrink)

The collection and disposal of rubbish and waste and the maintenance of a decent standard of hygiene was as much a problem for ancient city authorities as for modern town councils. The responsibility for the removal of waste would often be dependent upon the nature of the rubbish and the facilities which city authorities offered. Thus early in the fourth century B.C. the agoranomic law from Piraeus prohibited individuals from piling earth and other waste on the streets and compelled the (...) offender to remove it. The astynomic law from Pergamon, which probably dates originally to the Hellenistic period, similarly forbade the dumping or piling up of earth or the mixing of mortar on the streets of the city. As one of Demosthenes' speeches indicates, the effect of dumping rubbish indiscriminately was to raise the level of the road surface, which consequently restricted access and endangered adjacent property. Excavation of a triangular hieron to the south west of the agora at Athens further illustrates the results of dumping. Here it was found that, between the construction of the hieron in the late fifth century B.C. and the beginning of the fourth century B.C, the road surface on its northern side rose more than half a metre and covered the lower part of the wall of the hieron and its boundary marker. The accumulated fill included a deep layer of marble chips, which had been dumped in the area by marble workers. The laws from Piraeus and Pergamon were thus designed to keep streets passable, protect adjacent buildings, and safeguard pedestrians. (shrink)

Given the sordid history of injustices linking genetics to race and ethnicity, considerations of justice are central to ensuring the responsible development of precision medicine programmes around the world. While considerations of justice may be in tension with other areas of concern, such as scientific value or privacy, there are also tensions between different aspects of justice. This paper focuses on three particular aspects of justice relevant to this precision medicine: social justice, distributive justice and human rights. We describe the (...) implications of each for the use of race and ethnicity in precision medicine, and also how they intersect and potentially conflict with each another. By attending to these intersections, we aim to enrich and add nuance to debates over how best to proceed with precision medicine initiatives. (shrink)

Stanovich & West distinguish between evolutionary rationality and normative rationality, and System 1 and System 2 mental processes. They hold that the main function of System 2 has to do with normative and not evolutionary rationality. We ask how System 2 could then be an adaptation, especially given S&W's own work on individual differences.

What is truly beautiful? For Søren Kierkegaard the beautiful is to be found in an integrated self, one that is freely chosen. This article explores Kierkegaard's "aesthetic" stage of existence through the character of Augusto Pérez, the protagonist of Miguel de Unamuno's novel, Niebla. After establishing a solid link between Unamuno and Kierkegaard, Kierkegaard's "ethical" stage is used to critique the "aesthetic" stage on aesthetic grounds, on the basis of the beauty found in life's work, a calling. The conclusion is (...) that the sphere of the "aesthetic" does not achieve Kierkegaard's "aesthetics" of an integrated, fully existing self. (shrink)

Collaboration requires agents to coordinate their behavior on the fly, sometimes cooperating to solve a single task together and other times dividing it up into sub‐tasks to work on in parallel. Underlying the human ability to collaborate is theory‐of‐mind (ToM), the ability to infer the hidden mental states that drive others to act. Here, we develop Bayesian Delegation, a decentralized multi‐agent learning mechanism with these abilities. Bayesian Delegation enables agents to rapidly infer the hidden intentions of others by inverse planning. (...) We test Bayesian Delegation in a suite of multi‐agent Markov decision processes inspired by cooking problems. On these tasks, agents with Bayesian Delegation coordinate both their high‐level plans (e.g., what sub‐task they should work on) and their low‐level actions (e.g., avoiding getting in each other's way). When matched with partners that act using the same algorithm, Bayesian Delegation outperforms alternatives. Bayesian Delegation is also a capable ad hoc collaborator and successfully coordinates with other agent types even in the absence of prior experience. Finally, in a behavioral experiment, we show that Bayesian Delegation makes inferences similar to human observers about the intent of others. Together, these results argue for the centrality of ToM for successful decentralized multi‐agent collaboration. (shrink)
