Determinism fails easily if spacetimes with points removed from the spacetime manifold are taken to be physically reasonable representations of a way the world could be according to classical general relativity. I discuss a recently proposed condition for determining which spacetimes have holes—epistemic hole freeness—and show that epistemic hole freeness gives the correct verdict in some non-globally hyperbolic spacetimes with a closed subset removed, certain spacetimes with genuinely indeterministic features count as having an epistemic hole, which implies that the requirement (...) of epistemic hole freeness enforces a form of determinism, and there is a large class of spacetimes that intuitively are radically indeterministic and unphysical due to containing a hole, but are free from epistemic holes. I show that a few natural ways of remedying are not satisfactory. (shrink)

ABSTRACT The paper undertakes a critical analysis of the so-called Presupposition of the Spiritual Exercises of St. Ignatius Loyola, which prescribes the benevolent interpretation of the other’s words. We aim to identify the anthropological and epistemological background of the pedagogical guidelines contained therein and to explicate the intellectual and moral virtues needed to put them into practice. We argue that practising the Presupposition is both virtuous and mutually beneficial in pedagogical practice.

The kernel of this volume is an English translation of Jan Łukasiewicz’s classic work on the concept of cause (1906). It is the starting point for analytical considerations on causality of two generations of philosophers belonging to the tradition of the Lvov-Warsaw School.

I discuss candidates for definitions of determinism in the context of general relativistic spacetimes, and argue that a definition which does not make recourse to any particular region of spacetime should be preferred over alternatives; one such notion is discussed in detail in the light of various physical examples. The emerging picture of determinism is a pluralist one: sometimes there is no unique way of making our intuitive concept of determinism precise. Instead, what is crucial for assessment of determinism of (...) the theory are auxiliary conditions under which it counts as deterministic or indeterministic, and justification for using them in a given situation.

The article aims at analyzing the case of Beppe Grillo and his Five Stars Movement in terms of social, cultural and linguistic phenomenon that – initially as a virtual party without a structured organization – seems to conquer both right-wing and left-wing Italian citizens notwithstanding generational and ideological differences. The success of grillini in the parliamentary election of 2018 as a consequence of Matteo Renzi’s constitutional referendum failure, represents a clear sign of the leadership crisis as well as the drifting (...) apart of the ruling class that ignored the problems of ordinary people for several years. The analysis is focused on both form and content: on the one hand, the artistic expression characteristic of Grillo, his gestures, mimicry and direct language plenty of verbal hyperboles, rhetorical figures, swearwords and blasphemous obscenities that build his uncompromising charisma, on the other modern technologies and social media that are used to communicate efficiently with the electorate, create an image of an open-minded politician keeping up with the outer world. All the aforementioned circumstances demonstrate an innovative approach based on political communication that devolves some level of decision-making power to the party supporters being active web users: bloggers and influencers at the same time. Such paradigm is followed by other representatives of the Italian political scene nowadays. (shrink)

ABSTRACT Capital regulations stemming from the Basel accords created incentives for banks to securitize mortgages, even risky ones; hold them at a correspondingly low Basel risk weight; or shift them off of banks' balance sheets to obtain even greater leverage. Securitization was praised by economists and regulators for dispersing risks to investors across the world, providing greater resilience to the financial system. However, since in reality banks tended to hold onto securitized assets—either on their balance sheets or off of them, (...) in off‐balance‐sheet entities—the accumulated credit risk remained with the banks, especially in the “shadow banking sector.” This explains the heightened vulnerability of the financial system to a sudden collapse.

We discuss three philosophically interesting epistemic peculiarities of black hole astrophysics: (1) issues concerning whether and in what sense black holes do exist; (2) how to best approach multiplicity of available definitions of black holes; (3) short (i.e., accessible within an individual human lifespan) dynamical timescales present in many of the recent, as well as prospective, observations involving black holes. In each case we argue that the prospects for our epistemic situation are optimistic.

ABSTRACTThe inherent complexity of modern financial systems, and their basis in human behavior, make it hard to establish unequivocally the “who, what, where, when, and why” of the global financial crisis. However, after almost a decade, we know enough to discard much of what has, in the meantime, become folk wisdom about the causes of the debacle, including Wall Street bonus culture, bankers’ greed, the moral hazard of “too big to fail,” government intervention and deregulation. While each of these factors (...) may have played some role, the crisis can be much more accurately described as one of ignorance than malevolence. The common thread tying the emergence of the bubble to the disastrous consequences of its bursting is the misunderstanding of correlation and causation links in three key domains: economic policy, financial modeling, and the regulatory framework. These misunderstandings helped fuel the housing bubble and introduced fragility into the system, making it vulnerable to the bubble’s subsequent, unavoidable burst. (shrink)

This is an English translation of Juliusz Domański’s “Fausta Socyna Explicatio primae partis primi capitis Euangelii Ioannis i egzegeza erazmiańska,” in his "Erasmiana minora. Studia i szkice o pisarstwie filozoficznym i religijnym Erazma z Rotterdamu" (Warsaw: Instytut Tomistyczny, Instytut Filologii Klasycznej UW, 2017), 337–63. Translated with the Author’s permission. The paper compares the method of Biblical interpretation used by Erasmus of Rotterdam with the method of Socinus, raising the question of the extent to which the method outlined by Socinus (...) in his Explicatio primae partis primi capitis Euangelii Joannis can be seen as continuous and and consonant with the method of Erasmus, and to what extent it should be seen as its rejection or modification. In addition, the essay outlines similarities and differences, with respect to both method and content, between Erasmus' Adnotationes and Socinus’ Explicatio. (shrink)

Recent scholarship has underscored the possibility that capital-adequacy regulations may have contributed to the 2008 financial crisis by privileging highly rated asset-backed securities, such as mortgage-backed securities. The same regulations gave an even more privileged position to sovereign debt, leading to the question of whether they helped cause the European sovereign-debt crisis. There is little question that the regulations encouraged European banks to invest in European governments' bonds, but it does not appear that this encouragement led to more government borrowing (...) by significantly reducing the yield governments needed to pay on their debt. However, it does appear that capital-adequacy regulations—along with post-2008 liquidity regulations—concentrated sovereign risk in the European banking system, aggravating the sovereign-debt problem by requiring government bailouts that, in turn, required the issuance of more sovereign debt, further jeopardizing the governments' fiscal position and banks' solvency. Exacerbating the situation, in the midst of a panic, the European Banking Authority imposed new capital requirements on banks and effectively forced them to realize mark-to-market losses on sovereign exposures.

General relativity cannot be formulated as a perturbatively renormalizable quantum field theory. An argument relying on the validity of the Bekenstein–Hawking entropy formula aims at dismissing gravity as non-renormalizable per se, against hopes that d-dimensional GR could turn out to have a non-perturbatively renormalizable d–dimensional quantum field theoretic formulation. In this note we discuss various forms of highly problematic semi-classical extrapolations assumed by both sides of the debate concerning what we call The Entropy Argument, and show that a large class (...) of dimensional reduction scenarios leads to the blow-up of Bekenstein–Hawking entropy.
