It is a classical result of Mortimer that $L^2$ , first-order logic with two variables, is decidable for satisfiability. We show that going beyond $L^2$ by adding any one of the following leads to an undecidable logic:– very weak forms of recursion, viz.¶(i) transitive closure operations¶(ii) (restricted) monadic fixed-point operations¶– weak access to cardinalities, through the Härtig (or equicardinality) quantifier¶– a choice construct known as Hilbert's $\epsilon$ -operator.In fact all these extensions of $L^2$ prove to be undecidable both for satisfiability, (...) and for satisfiability in finite structures. Moreover most of them are hard for $\Sigma^1_1$ , the first level of the analytical hierachy, and thus have a much higher degree of undecidability than first-order logic. (shrink)

Shifting the focus from fear, guilt, and indignation related to deteriorating environmental quality, the authors hypothesized that people who see greater potential for restorative experiences in natural environments also do more to protect them by behaving ecologically, as with recycling or reduced driving. University students rated a familiar freshwater marsh in terms of being away, fascination, coherence, and compatibility, qualities of restorative person-environment transactions described in attention restoration theory. They also reported on their performance of various ecological behaviors. The authors (...) tested a structural equation model with data from a randomly drawn subset of participants and then confirmed it with the data from a second subset. For the combined subsets, perceptions of the restorative qualities predicted 23% of the variance in general ecological behavior. As the only direct predictor, fascination mediated the influences of coherence, being away, and compatibility. (shrink)

The fast recovery of Germany's economy after World War II—the so‐called “German miracle”—can be explained by the market‐oriented economic policies pursued in the 1950s, based upon the ideas of Ordoliberalism. The slounng growth rates and increasing economic difficulties since the 1970s seem to have resulted from the extension of interventionist and redistributionist policies beyond those sanctioned by Ordoliberalism. The roots of the German economic decline are political: already in the 1950s, a broad consensus existed about the need to integrate market‐oriented (...) economic policy with a highly redistributory welfare state in a “social market economy.”.

An “insightful” and in-depth look at anti-science politics and its deadly results (Maria Konnikova, New York Times–bestselling author of The Biggest Bluff). Thomas Jefferson said, “Wherever the people are well informed, they can be trusted with their own government.” But what happens when they aren’t? From climate change to vaccinations, transportation to technology, health care to defense, we are in the midst of an unprecedented expansion of scientific progress—and a simultaneous expansion of danger. At the very time we need them (...) most, scientists and the very idea of objective knowledge are being bombarded by a vast, well-funded war on science, and the results are deadly. Whether it’s driven by identity politics, ideology, or industry, the result is an unprecedented erosion of thought in Western democracies as voters, policymakers, and justices actively ignore scientific evidence, leaving major policy decisions to be based more on the demands of the most strident voices. This compelling book investigates the historical, social, philosophical, political, and emotional reasons why evidence-based politics are in decline and authoritarian politics are once again on the rise on both left and right—and provides some compelling solutions to bring us to our collective senses, before it's too late. “If you care about attacks on climate science and the rise of authoritarianism, if you care about biased media coverage and shake-your-head political tomfoolery, this book is for you.”—The Guardian.

Following its publication in Germany in 1963, Otto Friedrich Bollnow's Human Space quickly became essential reading within a cross-disciplinary field of subject areas including architecture, anthropology, and philosophy. In this first English translation, Bollnow conceives the human experience of space not merely as a philosophical problem but also as an extension of his research into psychology, human behavior, and the conventional domains of architecture: living in a building, in an apartment, in a house. Human Space is a remarkable investigation (...) of space as we experience it, by a man many consider to be the father of spatial and architectural anthropology. This lush hardcover edition includes an afterword by Joseph Kohlmaier that situates the work in the context of philosophical and architectural discussion. (shrink)

Enthält: Die Herkunft der platonischen Kardinaltugenden / Otto Kunsemüller. And, Kalos kai agathos / Hermann Wankel.

Theologie / Altes Testament Philo von Alexandrien nimmt eine Schlüsselstellung in der hellenistischen Geistesgeschichte ein, weil er der erste mittelplatonische Denker gewesen ist, dessen Schriften zum größten Teil überliefert sind. Seine Schriften sind darüber hinaus eine unentbehrliche Quelle für die hellenistische und stoische Philosophie, deren Werke nicht erhalten sind. Seine theologiegeschichtliche Bedeutung beruht darauf, dass er sich als Erster bei seinen Auslegungen der Fünft Bücher Mose zur Welt- und Existenzerhellung der ihm vorliegenden Schriften der griechischen Philosophen und...
