Ivan Efimovič Orlov’s paper “The calculus of the compatibility of propositions”, published in Russian in 1928, is fascinating for anyone interested in the early history of relevance, modal or intuitionistic logic. This is a guide that outlines Orlov's life and work, analyses the content of the paper, and relates it to work of his contemporaries and successors.

Ivan Efimovič Orlov’s paper “The calculus of the compatibility of propositions”, published in Russian in 1928, is fascinating for anyone interested in the early history of relevance, modal or intuitionistic logic. This is a translation of that paper.

Le philosophe russe Nicolai Vasiliev est connu en tant que précurseur des logiques essentiellement non-classiques, c'est-à-dire de logiques qui diffèrent de la logique classique par l'abandon de principes qui sont corrects en logique classique. La gamme de telles logiques couvre la logique intuitionniste, la logique plurivalente, la logique paraconsistante et les logiques de la pertinence. Dans la première partie de ce texte, j'analyse brièvement les vues de Vasiliev, à savoir sa « logique imaginaire », qu'il présente comme une nouvelle logique (...) non-aristotélicienne. Dans les sections suivantes je discute l'impact des approches de Vasiliev sur la logique du consentement. Ici, les idées essentiellement non-classiques de Vasiliev seront reliées à des logiques non- essentiellement non-classiques, qui ne constituent pas une révision de la logique classique, mais étendent sa puissance expressive.

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)

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)

Stance-independent nonnaturalist moral realism is subject to two related epistemological objections. First, there is the metaethical descendant of the Benacerraf problem. Second, there are evolutionary debunking arguments. Standard attempts to solve these epistemological problems have not appealed to any particular moral epistemology. The focus on these epistemologically neutral responses leaves many interesting theoretical stones unturned. Exploring the ability of particular theories in moral epistemology to handle these difficult epistemological objections can help illuminate strengths or weaknesses within these theories themselves, as (...) well as opening up potentially unexplored avenues for responding to deeply entrenched concerns about our epistemic access to the moral properties. In this paper, I assess the prospects of an empiricist and perceptualist model of moral knowledge for responding to epistemological arguments against non-skeptical moral realism. I argue that such a view has powerful responses to these objections that are not open to other moral epistemologists. The upshot is that if some version of the view is correct, then the realist has less to fear from Benacerraf and evolutionary debunking–style epistemological objections. Insofar as one is already a committed realist, then, this provides some indirect support for moral perceptualism. (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.

This article focuses on unjust credibility deficits in cases of testimony about emotional reactions towards acts of oppression. It argues that the injustice in these cases is not rooted in the hearer’s identity prejudices against the speaker, but the hearer's problematic way of dealing with his simulation of being in the speaker's situation. The simulation is in itself not morally problematic. However, I focus on a case where the hearer either recklessly or negligently fails to consider knowledge about the differences (...) in people’s emotional reactions and comes to believe that his simulated reaction is the only possible reaction, thus believing that the speaker does not report her emotions truthfully.In this case, the ‘epistemic poison’ results from the recklessness or negligence not necessarily from identity prejudice against the speaker. This credibility deficit is unjust, yet its persistent and systematic nature stems from the fact that a hearer who is not from the same marginalized or oppressed group as the speaker will simulate different emotional reactions to those reported by the speaker. Hence, the unjust credibility deficit can be connected to other forms of social injustices suffered by the speaker. (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)
