We address the need for a model by considering two competing theories regarding the origin of life: (i) the Metabolism First theory, and (ii) the RNA World theory. We discuss two interrelated points, namely: (i) Models are valuable tools for understanding both the processes and intricacies of origin-of-life issues, and (ii) Insights from models also help us to evaluate the core objection to origin-of-life theories, called “the inefficiency objection”, which is commonly raised by proponents of both the Metabolism First theory (...) and the RNA World theory against each other. We use Simpson’s Paradox (SP) as a tool for challenging this objection. We will use models in various senses, ranging from taking them as representations of reality to treating them as theories/accounts that provide heuristics for probing reality. In this paper, we will frequently use models and theories interchangeably. Additionally, we investigate Conway’s Game of Life and contrast it with our SP-based approach to emergence-of-life issues. Finally, we discuss some of the consequences of our view. A scientific model is testable in three senses: (i) a logical sense, (ii) a nomological sense, and (iii) a current technological sense. The SP-based model is testable in the first two senses but it is not feasible to test it using current technology. (shrink)

1) Introduction. 2) The key libertarian insight into property and orthodox libertarianism’s philosophical confusion. 3) Clearer distinctions for applying to what follows: abstract liberty; practical liberty; moral defences; and critical rationalism. 4) The two dominant (‘Lockean’ and ‘Hobbesian’) conceptions of interpersonal liberty. 5) A general account of libertarianism as a subset of classical liberalism and defended from a narrower view. 6) Two abstract (non-propertarian, non-normative) theories of interpersonal liberty developed and defended: ‘the absence of interpersonal initiated imposed constraints on want-satisfaction’, (...) abbreviated to ‘no initiated imposed costs’; and ‘no imposed costs’. 7) Practical implications for both main abstract conceptions of liberty derived and compared. 8) How this positive analysis relates to morals. 9) Concluding conjectures: the main abstract theory of liberty captures the relevant interpersonal conception; the new paradigm of libertarianism solves the old one’s problems.

Although expected utility theory has proven a fruitful and elegant theory in the finite realm, attempts to generalize it to infinite values have resulted in many paradoxes. In this paper, we argue that the use of John Conway's surreal numbers shall provide a firm mathematical foundation for transfinite decision theory. To that end, we prove a surreal representation theorem and show that our surreal decision theory respects dominance reasoning even in the case of infinite values. We then bring our theory (...) to bear on one of the more venerable decision problems in the literature: Pascal's Wager. Analyzing the wager showcases our theory's virtues and advantages. To that end, we analyze two objections against the wager: Mixed Strategies and Many Gods. After formulating the two objections in the framework of surreal utilities and probabilities, our theory correctly predicts that (1) the pure Pascalian strategy beats all mixed strategies, and (2) what one should do in a Pascalian decision problem depends on what one's credence function is like. Our analysis therefore suggests that although Pascal's Wager is mathematically coherent, it does not deliver what it purports to, a rationally compelling argument that people should lead a religious life regardless of how confident they are in theism and its alternatives.

It has long been the position in law that, subject to some minor but important exceptions, property cannot be held in the human body, whether living or dead. In the recent case of Yearworth and Others v North Bristol NHS Trust, however, the Court of Appeal for England and Wales revisited the property debate and threw into doubt a number of doctrines with respect to property and the body. This brief article analyses Yearworth, (1) reviewing the facts and the Court’s (...) decision with respect to the originators’ proprietary and contractual interests in their body and bodily products, (2) considering the significance of relying on property and its use a legal metaphor, (3) questioning the scope of the property right created, and (4) querying whether an alternate conceptual approach to extending rights and a remedy was warranted. It concludes that, while Yearworth engages with, and impacts on, important theoretical and practical issues—from legal, healthcare and research perspectives—it does not offer a great deal of guidance and, for that reason, its precedential significance is in doubt.

Conway characterizes freedom in apparently contradictory ways. She describes God as the most free, yet he is necessitated to act perfectly due to his wisdom and goodness. Created beings, by contrast, sin. They are not necessitated to do so. This suggests that Conway has a binary account of freedom: divine freedom is a matter of being necessitated by wisdom and goodness, whereas creaturely freedom consists in indifference, understood as a power to act, or not act. Despite the apparently conflicting remarks, (...) I argue that Conway has a single account of freedom as spontaneity. Conway defines spontaneity in terms of causing one’s own action independent of external causes. I suggest that spontaneity is more precisely understood as an intrinsic power aimed at the good in Conway’s metaphysics, and that this account of freedom can combine necessity and contingency. Rather than a binary, Conway offers an account of freedom in creation that has it on a continuum with divine freedom. (shrink)

This essay examines several works that contribute to an understanding of the nature of contemporary Chinese capitalism and its historical development. Core issues include the character of the bureaucracy, which has had a distinctive relationship to capital formation, and the character of the working class. The periodisation of Chinese capitalism and the relation between the pre- and post-reform periods are pressing political and analytical concerns. This essay suggests the advantages of a clearer focus on the dynamics of depoliticisation in understanding (...) the transition. The contemporary left-intelligentsia in China has in large part pinned its hopes on achieving some form of ideological hegemony within theccp, maintaining that it still operates within its revolutionary tradition. This represents a questionable strategic gamble. Acknowledging the important contributions made by Au’s book and other recent characterisations of China’s political economy from the left, this essay suggests that there remains much to be done.
