Innovative forms of green urban architecture aim to combine food, production, and design to produce food on a larger scale in and on buildings in urban areas. It includes rooftop gardens, rooftop greenhouses, indoor farms, and other building-related forms. This study uses the framework of sustainability to understand the role of ZFarming in future urban food production and to review the major benefits and limitations. The results are based on an analysis of 96 documents published in accessible international resources. The (...) analysis shows that ZFarming has multiple functions and produces a range of non-food and non-market goods that may have positive impacts on the urban setting. It promises environmental benefits resulting from the saving and recycling of resources and reduced food miles. Social advantages include improving community food security, the provision of educational facilities, linking consumers to food production, and serving as a design inspiration. In economic terms it provides potential public benefits and commodity outputs. However, managing ZFarming faces several challenges. For some applications, the required technologies are known but have not been used or combined in that way before; others will need entirely new materials or cultivation techniques. Further critical aspects are the problem of high investment costs, exclusionary effects, and a lack of acceptance. In conclusion, ZFarming is seen as an outside-the-box solution which has some potential in generating win–win scenarios in cities. Nevertheless, ZFarming practices are not in and of themselves sustainable and need to be managed properly. (shrink)

In solving judgment aggregation problems, groups often face constraints. Many decision problems can be modelled in terms the acceptance or rejection of certain propositions in a language, and constraints as propositions that the decisions should be consistent with. For example, court judgments in breach-of-contract cases should be consistent with the constraint that action and obligation are necessary and sufficient for liability; judgments on how to rank several options in an order of preference with the constraint of transitivity; and judgments on (...) budget items with budgetary constraints. Often more or less demanding constraints on decisions are imaginable. For instance, in preference ranking problems, the transitivity constraint is often contrasted with the weaker acyclicity constraint. In this paper, we make constraints explicit in judgment aggregation by relativizing the rationality conditions of consistency and deductive closure to a constraint set, whose variation yields more or less strong notions of rationality. We review several general results on judgment aggregation in light of such constraints. (shrink)

Plato's dialogues frequently criticize traditional Greek myth, yet Plato also integrates myth with his writing. Daniel S. Werner confronts this paradox through an in-depth analysis of the Phaedrus, Plato's most mythical dialogue. Werner argues that the myths of the Phaedrus serve several complex functions: they bring nonphilosophers into the philosophical life; they offer a starting point for philosophical inquiry; they unify the dialogue as a literary and dramatic whole; they draw attention to the limits of language and the (...) limits of knowledge; and they allow Plato to co-opt cultural authority as a way of defining and legitimating the practice of philosophy. Platonic myth, as a species of traditional tale, is thus both distinct from philosophical dialectic and similar to it. Ultimately, the most powerful effect of Platonic myth is the way in which it leads readers to participate in Plato's dialogues and to engage in a process of self-examination. (shrink)

Called by Karl Barth the brilliant Ethics of Dietrich Bonhoeffer, this book is finally being recognized as Bonhoeffers magnum opus and one of the most important works of Christian ethics of the last century.

Agents are often assumed to have degrees of belief (“credences”) and also binary beliefs (“beliefs simpliciter”). How are these related to each other? A much-discussed answer asserts that it is rational to believe a proposition if and only if one has a high enough degree of belief in it. But this answer runs into the “lottery paradox”: the set of believed propositions may violate the key rationality conditions of consistency and deductive closure. In earlier work, we showed that this problem (...) generalizes: there exists no local function from degrees of belief to binary beliefs that satisfies some minimal conditions of rationality and non-triviality. “Locality” means that the binary belief in each proposition depends only on the degree of belief in that proposition, not on the degrees of belief in others. One might think that the impossibility can be avoided by dropping the assumption that binary beliefs are a function of degrees of belief. We prove that, even if we drop the “functionality” restriction, there still exists no local relation between degrees of belief and binary beliefs that satisfies some minimal conditions. Thus functionality is not the source of the impossibility; its source is the condition of locality. If there is any non-trivial relation between degrees of belief and binary beliefs at all, it must be a “holistic” one. We explore several concrete forms this “holistic” relation could take. (shrink)

The Christian does not live in a vacuum, says the author, but in a world of government, politics, labor, and marriage. Hence, Christian ethics cannot exist in a vacuum what the Christian needs, claims Dietrich Bonhoeffer, is concrete instruction in a concrete situation. Although the author died before completing his work, this book is recognized as a major contribution to Christian ethics. The root and ground of Christian ethics, the author says, is the reality of God as revealed in (...) Jesus Christ. This reality is not manifest in the Church as distinct from the secular world such a juxtaposition of two separate spheres, Bonhoeffer insists, is a denial of God's having reconciled the whole world to himself in Christ. On the contrary, God's commandment is to be found and known in the Church, the family, labor, and government. His commandment permits man to live as man before God, in a world God made, with responsibility for the institutions of that world. (shrink)

Presents German physicist Werner Heisenberg's 1958 text in which he discusses the philosophical implications and social consequences of quantum mechanics and other physical theories.

Modal dispositionalists hold that dispositions provide the foundation of metaphysical necessity and possibility. According to the kind of modal dispositionalism that can be found in the present literature, a proposition p is possible just in case some things are disposed to be such that p. In the first part of this paper I show that combining this classic form of dispositionalism with the assumptions that the laws of nature are necessary and deterministic and that all dispositions are forward-looking in time (...) leads to the unattractive conclusion that every truth is necessary. I argue that the classic dispositionalist should be troubled by this result and in the second part of the paper I suggest a novel variant of dispositionalism that avoids it. This extended form of dispositionalism allows that some propositions are only indirectly underwritten by dispositions. (shrink)

There is a prevalent notion among cognitive scientists and philosophers of mind that computers are merely formal symbol manipulators, performing the actions they do solely on the basis of the syntactic properties of the symbols they manipulate. This view of computers has allowed some philosophers to divorce semantics from computational explanations. Semantic content, then, becomes something one adds to computational explanations to get psychological explanations. Other philosophers, such as Stephen Stich, have taken a stronger view, advocating doing away with semantics (...) entirely. This paper argues that a correct account of computation requires us to attribute content to computational processes in order to explain which functions are being computed. This entails that computational psychology must countenance mental representations. Since anti-semantic positions are incompatible with computational psychology thus construed, they ought to be rejected. Lastly, I argue that in an important sense, computers are not formal symbol manipulators. (shrink)

Affective congruency effects in the evaluation task can be explained by either spreading of activation or response competition. Eliminating effects of response compatibility by using other tasks (semantic categorisation, naming task) typically also eliminates affective congruency effects. However, there is no need for processing the affective information of the stimuli in these tasks either, which could be necessary for an affectively mediated spreading of activation (Spruyt et al., 2007, 2009, 2012). We introduced a new task to further test this hypothesis. (...) The valent/neutral-categorisation task does not confound affective congruency with response compatibility, but still requires a processing of the stimuli's valence. No affective congruency effect was obtained with this task in two experiments, disfavouring a conditional spreading activation account. On the other hand, a significant priming effect was found for associated word pairs in Experiment 1, providing evidence for the sensitivity of the task to detect spreading activation processes.

The widely discussed "discursive dilemma" shows that majority voting in a group of individuals on logically connected propositions may produce irrational collective judgments. We generalize majority voting by considering quota rules, which accept each proposition if and only if the number of individuals accepting it exceeds a given threshold, where different thresholds may be used for different propositions. After characterizing quota rules, we prove necessary and sufficient conditions on the required thresholds for various collective rationality requirements. We also consider sequential (...) quota rules, which ensure collective rationality by adjudicating propositions sequentially and letting earlier judgments constrain later ones. Sequential rules may be path-dependent and strategically manipulable. We characterize path-independence and prove its essential equivalence to strategy-proofness. Our results shed light on the rationality of simple-, super-, and sub-majoritarian decision-making. (shrink)

Behaviourism is the view that preferences, beliefs, and other mental states in social-scientific theories are nothing but constructs re-describing people's behaviour. Mentalism is the view that they capture real phenomena, on a par with the unobservables in science, such as electrons and electromagnetic fields. While behaviourism has gone out of fashion in psychology, it remains influential in economics, especially in ‘revealed preference’ theory. We defend mentalism in economics, construed as a positive science, and show that it fits best scientific practice. (...) We distinguish mentalism from, and reject, the radical neuroeconomic view that behaviour should be explained in terms of brain processes, as distinct from mental states. (shrink)

In the theory of judgment aggregation, it is known for which agendas of propositions it is possible to aggregate individual judgments into collective ones in accordance with the Arrow-inspired requirements of universal domain, collective rationality, unanimity preservation, non-dictatorship and propositionwise independence. But it is only partially known (e.g., only in the monotonic case) for which agendas it is possible to respect additional requirements, notably non-oligarchy, anonymity, no individual veto power, or implication preservation. We fully characterize the agendas for which there (...) are such possibilities, thereby answering the most salient open questions about propositionwise judgment aggregation. Our results build on earlier results by Nehring and Puppe (2002), Nehring (2006), Dietrich and List (2007a) and Dokow and Holzman (2010a). (shrink)

There are many possible ways to approach the topic of educational theory and critique. One could inquire into the meaning of critical phenomena and subject-matter in practical education and instruction, investigate the various forms of critique with the goal of determining the extent to which they assist in clarifying pedagogical action, or one could ask: ‘What is meant by critical educational research?’ and ‘How do the various approaches to this topic relate to one another?’. This article inquires into the relationship (...) between critique and negativity. Such a distinction is relevant for the practical, theoretical and research-oriented use of the various forms and subject matters of critique. This analysis of their relationship aims to clarify how the structure of human learning connects to that of pedagogical action; and, additionally, how the theoretical guidelines and orientation for pedagogical action relate to scientific analyses and research in education in a way that is productive. Distinctions made in thought, judgement and action are not simply delimiting positive characteristics. Such distinctions are at once mediated by the relations of knowledge and ignorance, ability and inability. Although ignorance and inability can be transformed into positive knowledge and ability, they are not superseded in the process. Ignorance and inability are, on the contrary, constitutive elements of learning. The possibility for transitions from ignorance and inability to knowledge and ability—a possibility that itself presupposes knowledge and ability—point to a form of negativity within the process of education (Bildung). This form of negativity relates to the human ability to learn (Bildsamkeit) and provides the definitive basis of human learning. A form of negativity constitutive of learning processes leads to one that grounds pedagogical processes. Pedagogical efficacy is mediated by a double negativity, comprised of both a universal and a particular form of negativity. The relation of negativity to learning and pedagogical efficacy, with specific reference to educational research studies on teaching and learning processes, is considered. A form of educational research that operates beyond fundamentalist criticisms—that is to say, criticisms based on unshakeable beliefs—and utilises issues arising from a pluralisation of critique to confront the pluralism of critical positions, is considered. The article closes with reflections on the relation between the Critical and the Uncritical. (shrink)

This paper discusses a puzzle raised by Sharon Berry, published in Analysis. The question in the background of this puzzle is how we should deal with seemingly plausible possibility judgements that commit us to counterfactual truths that find no basis in reality. Three answers to this question and their corresponding solutions to the puzzle will be discussed. The last answer provides a way to make sense of the claim that it is in some cases indeterminate whether a proposition is possible (...) and offers an account of indeterminate modal status. (shrink)

We introduce a “reason-based” framework for explaining and predicting individual choices. It captures the idea that a decision-maker focuses on some but not all properties of the options and chooses an option whose motivationally salient properties he/she most prefers. Reason-based explanations allow us to distinguish between two kinds of context-dependent choice: the motivationally salient properties may (i) vary across choice contexts, and (ii) include not only “intrinsic” properties of the options, but also “context-related” properties. Our framework can accommodate boundedly rational (...) and sophisticatedly rational choice. Since properties can be recombined in new ways, it also offers resources for predicting choices in unobserved contexts. (shrink)

Der logische Status dessen, was in der Hegelschen Terminologie «Begriff» heisst, kann nur als seine eigene Genese zur Darstellung kommen. In ihm sind die Formen der Positivität, die durch die Subjekt-Objekt-Relation charakterisiert sind, als Momente enthalten. Die Einsicht in die einzelnen Formen der Positivität ermöglicht es, sich einen Begriff von der Sprachlichkeit des Selbstbewusstseins zu machen.

All existing impossibility theorems on judgment aggregation require individual and collective judgment sets to be consistent and complete, arguably a demanding rationality requirement. They do not carry over to aggregation functions mapping profiles of consistent individual judgment sets to consistent collective ones. We prove that, whenever the agenda of propositions under consideration exhibits mild interconnections, any such aggregation function that is "neutral" between the acceptance and rejection of each proposition is dictatorial. We relate this theorem to the literature.

Which rules for aggregating judgments on logically connected propositions are manipulable and which not? In this paper, we introduce a preference-free concept of non-manipulability and contrast it with a preference-theoretic concept of strategy-proofness. We characterize all non-manipulable and all strategy-proof judgment aggregation rules and prove an impossibility theorem similar to the Gibbard--Satterthwaite theorem. We also discuss weaker forms of non-manipulability and strategy-proofness. Comparing two frequently discussed aggregation rules, we show that “conclusion-based voting” is less vulnerable to manipulation than “premise-based voting”, (...) which is strategy-proof only for “reason-oriented” individuals. Surprisingly, for “outcome-oriented” individuals, the two rules are strategically equivalent, generating identical judgments in equilibrium. Our results introduce game-theoretic considerations into judgment aggregation and have implications for debates on deliberative democracy. (shrink)

Recently, a number of philosophers of biology have endorsed views about random drift that, we will argue, rest on an implicit assumption that the meaning of concepts such as drift can be understood through an examination of the mathematical models in which drift appears. They also seem to implicitly assume that ontological questions about the causality of terms appearing in the models can be gleaned from the models alone. We will question these general assumptions by showing how the same equation (...) — the simple 2 = p2 + 2pq + q2 — can be given radically different interpretations, one of which is a physical, causal process and one of which is not. This shows that mathematical models on their own yield neither interpretations nor ontological conclusions. Instead, we argue that these issues can only be resolved by considering the phenomena that the models were originally designed to represent and the phenomena to which the models are currently applied. When one does take those factors into account, starting with the motivation for Sewall Wright’s and R.A. Fisher’s early drift models and ending with contemporary applications, a very different picture of the concept of drift emerges. On this view, drift is a term for a set of physical processes, namely, indiscriminate sampling processes. (shrink)

This article is about the 500 hundred year commemoration of the Reformation in 2017. However, the question is to be asked: What should we celebrate in 2017? The article reflects on this question against the background of the ongoing division within Western Christianity. It discusses objectives laid out by Wolfgang Huber in 2008 for the Luther Decade. These objectives focus on the relationship between church and society, and particularly Lutheran-themes such as ‘hopelessnesses of life’, ‘afflictions of faith’, ‘God’s hiddenness’ and (...) the ‘theology of the cross’. The article demonstrates that the soteriological focal point of Biblical-Lutheran theology reflects the assertion that it is only God who, through the belief in Christ, awards freedom and dignity to every human. The Church represents the ‘metaphor of a Christian fellowship’, which is a fellowship of equals that provides a socio-political impetus. (shrink)

This paper argues that institutions are higher-level autonomous systems enacted by patterns of participatory sense-making. Therefore, unlike in the standard equilibrium theory, institutions are not themselves thought of as behavioural patterns. Instead, they are problem domains that these patterns have brought forth. Moreover, these are not merely any patterns, but only those devoted to maintaining a specific strategy of problem solving, called the strategy of ‘letting be’. The latter refers to, following Hanne de Jaegher, a balance between underdetermination and overdetermination (...) of individual behaviour by a collective. Such an understanding of institutions becomes an option once a hybrid ‘equilibrium + rules’ theory of institutions, such as the one proposed by Frank Hindriks, is supplemented with insights from enactivism. In this light, drawing a connection between these two areas is the additional, meta-theoretical goal of this paper. This connection is beneficial, I argue, in particular since it allows for a satisfactory, in-depth account of the normative character of institutions as well as their local character. (shrink)
