Justice Across Ages offers an attractive account of justice between the young and the old that brings together three notable principles of age-group justice: complete-lives equality, relational equality, and prudence. Yet, the book says little about the fact that many of us live longer than others, and the little it does say casts doubt on whether lifespan inequality threatens justice as construed by the three principles. This essay argues, instead, that theories of justice between the young and the old should (...) not dispense with a conception of justice between different longevity groups. It concludes that we must be sensitive to lifespan variations when designing policies to promote justice across age groups. (shrink)

Retirement is often viewed as a reward for a working life. While many have reason to want a work-free retirement, not everyone does. Should working retirees have to give up their retirement pension and, consequently, their status as retirees? The answer, I argue, boils down to whether we conceive of retirement as free time (need-free) or as leisure (work-free). In this article, I put forward a liberal case in favour of free time, despite whether our liberalism leans towards perfectionism or (...) neutralism, with social primary goods being a case in point. Applying this case for free time to retirement yields two significant policy implications. First, it demands “free synchronic combination” – that retirees may use their retirement pensions however they see fit, including to work. Second, it also yields “free diachronic combination” – that, within limits, individuals have discretionary control over how to combine retirement and work across time – thus challenging the idea that retirement should be available only in old age and not earlier in life. So far, the literature on free time focused only on narrow temporal units, such as hours and days, but there is much to gain by extending the concept into retirement. (shrink)

Die Epitome physica des Nikephoros Blemmydes (1197 – nach 1269) gilt als eines der meistverbreiteten Lehrbücher aristotelischer Naturphilosophie in der byzantinischen und nachbyzantinischen Welt. Dennoch blieb die handschriftliche Überlieferung bisher gänzlich unerforscht und der Text wurde nie in Form einer kritischen Edition zugänglich gemacht. Die Epitome physica stellt das zweite Buch der Εἰσαγωγικὴ ἐπιτομή (Einführendes Kompendium) dar, deren erstes Buch der Logik gewidmet ist. Als Grundlage dienten Blemmydes im Wesentlichen Aristoteles und seine Kommentatoren (sowie für den astronomischen Teil den Stoiker (...) Kleomedes), wobei er versuchte, eine Synthese der antiken Naturphilosophie mit der christlichen Weltanschauung zu erreichen. Von den über 120 erhaltenen Manuskripten der Epitome, die vom 13. bis ins 19 Jh. datieren, werden im vorliegenden Buch die Handschriften aus der Palaiologenzeit sowie die Mehrheit derjenigen aus der Renaissance manuskriptologisch und philologisch untersucht sowie ihre textgeschichtlichen Beziehungen rekonstruiert. Daneben kommen auch die Verbreitung und der kulturelle Stellenwert der Epitome physica in der byzantinischen Welt und in der europäischen Renaissance zur Darstellung. (shrink)

A prova é a medula do processo penal de qualquer sistema jurídico-constitucional. A preservação da sua originalidade e da sua integridade é essencial e vital à realização da justiça assente numa descoberta da verdade processual prática, material, judicial e válida, de modo que possamos afirmar que os direitos e liberdades fundamentais de todos os afetados pelo processo-crime sejam garantidos e, assim, restabelecida a paz jurídica e social. Defendemos, pois e uma vez mais, que a legitimidade, a legalidade e a licitude (...) da prova são nucleares a um processo penal de um Estado constitucional democrático. (shrink)

There is a constructive method to define a structure of simple k-cyclic Post algebra of order p, L p,κ, on a given finite field F, and conversely. There exists an interpretation Ф₁ of the variety V generated by L p,κ into the variety V) generated by F and an interpretation Ф₂ of V) into V such that Ф₂Ф₁ = B for every B ϵ V and Ф₁₂ = R for every R ϵ V). In this paper we show how we (...) can solve an algebraic system of equations over an arbitrary cyclic Post algebra of order p, p prime, using the above interpretation, Gröbner bases and algorithms programmed in Maple.

We present an approach in which ancient Greek mathematical proofs by Hippocrates of Chios and Euclid are addressed as a form of (guided) intentional reasoning. Schematically, in a proof, we start with a sentence that works as a premise; this sentence is followed by another, the conclusion of what we might take to be an inferential step. That goes on until the last conclusion is reached. Guided by the text, we go through small inferential steps; in each one, we go (...) through an autonomous reasoning process linking the premise to the conclusion. The reasoning process is accompanied by a metareasoning process. Metareasoning gives rise to a feeling-knowing of correctness. In each step/cycle of the proof, we have a feeling-knowing of correctness. Overall, we reach a feeling of correctness for the whole proof. We suggest that this approach allows us to address the issues of how a proof functions, for us, as an enabler to ascertain the correctness of its argument and how we ascertain this correctness.

Universal basic income proposes providing instalments of constant magnitude to all. One problem with a stable basic income across life is that it seems unfair to shorter-lived persons, who are worst-off due to premature death and receive less over their whole lives. Basic capital solves this problem by providing a one-off grant to the young, but I argue that it mistreats long-lived persons, as it does not guarantee their real freedom across life. There is a dilemma between these proposals regarding (...) their respective unfairness to the short- and long-lived. The solution I propose is a net basic income of decreasing magnitude until a specific age, after which the income is constant. This solution is compatible with constant income benefits across life, and it offers a fair answer to the problem of unequal longevity, a widely neglected but essential challenge in debates about basic income.
