Taking a detour to reach a goal is intelligent behavior based on making inferences. The main purpose of the present research is to show how such apparently complex behavior can emerge from basic mechanisms such as contextual categorisation and goal attribution when perceiving people. We presentacacia (Action by Contextually Automated Categorising Interactive Agents), a computer model implemented using StarLogo software, grounded in the principles of Artificial Life (Al), capable of simulating the behavior of a group of agents with a goal (...) (for instance, to find a treasure in a treasure hunt ) in an environment where obstacles mask the goal site. The results of the simulations show that agents reach the goal the fastest when they follow each other and take detours. We argue that these results indicate that intelligent adaptive behavior is based on the contextual categorisation of environmental constrainst (that is, obstacles and other agents). (shrink)
Are concepts stable entities, unchanged from context to context? Or rather are they context-dependent structures, created on the fly? We argue that this does not constitute a genuine dilemma. Our main thesis is that the more a pattern of features is general and shared, the more it qualifies as a concept. Contextualists have not shown that conceptual structures lack a stable, general core, acting as an attractor on idiosyncratic information. What they have done instead is to give a contribution to (...) the comprehension of how conceptual structure organized around such a stable core can produce contextually appropriate representations on demand.

P.T. Geach has maintained (see, e.g., Geach (1967/1968)) that identity (as well as dissimilarity) is always relative to a general term. According to him, the notion of absolute identity has to be abandoned and replaced by a multiplicity of relative identity relations for which Leibniz’s Law – which says that if two objects are identical they have the same properties – does not hold. For Geach relative identity is at least as good as Frege’s cardinality thesis – which he takes (...) to be strictly connected with relative identity – according to which an ascription of cardinality is always relative to a concept which specifies what, in any particular case, counts as a unit. The idea that there is a close connection between relative identity and Frege’s cardinality thesis has been issued again quite recently by Alston and Bennett in (1984). In their opinion, Frege’s cardinality thesis is not only similar to relative identity – as Geach maintains – but it implies it. Moreover, they agree with Geach in claiming that a commitment to Frege’s cardinality thesis forces a parallel commitment to relative identity. Against Geach, Alston and Bennett we will claim that (T1): «Frege’s cardinality thesis is similar to relative identity» is false and that therefore (T2) «Frege’s cardinality thesis implies relative identity» is false as well.

The ?traditional? conception of toleration, understood as the putting up with beliefs and practices by those who disapprove of them, has come under increasing attack in recent years for being negative, condescending and judgemental. Instead, its critics argue for a more positive, affirmative conception, perhaps best captured by Anna Elisabetta Galeotti?s idea of ?toleration as recognition?. In this article, without denying that it is not always the most appropriate form of response to differences, I defend the traditional conception of (...) toleration against its critics. Two principal arguments are advanced in defence of it: the first articulates its role as part of a viable and realistic political theory of modus vivendi, while the second argues that it is only the traditional conception of toleration that makes possible the mutual accommodation of some values that are genuinely antithetical and hostlie to each other. Thus, there remains an important place for the traditional conception of toleration in both political theory and practice. (shrink)
In this essay, I reconstruct tolerance as a moral virtue, by critically analysing its definition, circumstances, justification and limits. I argues that, despite its paradoxical appearance, tolerance qualifies as a virtue, by means of a restriction of its proper object to differences that are chosen. Since this excludes the most important and divisive differences of contemporary pluralism from the scope of the virtue of tolerance, the moral model of toleration cannot constitute the micro-foundation of the corresponding political practice. However, if (...) the political ideal of toleration must be founded on independent political reasons of justice, the moral model can bridge the gap between private morality and public reason, providing citizens with moral motives to supplement the political obligation to neutrality.

This paper explores the possibility of resisting meaning scepticism – the thesis that there are many alternative incompatible assignments of reference to each of our terms - by appealing to the idea that the nature of reference is to maximize knowledge. If the reference relation is a knowledge maximizing-relation, then some candidate referents are privileged among the others - i.e., those referents we are in a position to know about – and a positive reason against meaning scepticism is thus individuated. (...) A knowledge-maximizing principle on the nature of reference was proposed by Williamson in a recent paper (Williamson 2005). According to Williamson, such a principle would count as a defeasible reason for thinking that most of our beliefs tend to be true. My paper reverses Williamson’s dialectic, and argues that reference is knowledge-maximizing from the premise that most of our beliefs tend to be true. (shrink)
According to Frege a proposition—or, in his terms, a thought—is an abstract structured entity constituted by senses which satisfies, at least, the three following properties: it can be semantically assessed as true or as false, it is the object of so called propositional attitudes and it can be grasped. What Frege meant by 'grasping' is the peculiar way in which we can have epistemic access to propositions. The possibility for propositions to be grasped is put by Frege as a warrant (...) for their existence: to challenge their graspability would amount to jeopardise their ontological reality. But is it true, as Frege uncritically maintained, that the "graspability requirement" is satisfied as far as propositions (as he conceived them) are concerned? This is the topic of the present work. A negative answer to the above mentioned question has been given in recent time by the representatives of what has come to be labelled the "cognitive turn" in analytical philosophy. People such as Fodor and Johnson-Laird patently denied the possibility for propositions, conceived à la Frege, to be accessed by the grasping relation. What grounds their position is, to put it roughly, the following train of thought: in order for something to be the target of the grasping relation it must enter the mind. Nothing which is different from a mental entity can enter the mind. Therefore, what can be grasped must be mental. The upshot of this move implies, among other things, the rejection of that radical anti-psychologism which was characteristic of the forefathers of the analytical tradition. In our work we shall try to resist their conclusion by showing that it is not necessary to zero the distinction between propositions and mental entities in order to provide an adequate account of the grasping relation. What one has to give up, instead, is only Frege's late Platonism of the "third realm" which, in our view, is a wholly unnecessary and dispensable accretion of his picture. For, as we shall show, if Platonism is in place it is difficult to provide an account of the grasping relation which makes no use of the "representationalist hypothesis" — i.e. of the hypothesis that ideas mediate our access to whatever can be given to us. But representationalism, once in place, makes the theoretical role of the notion of sense dispensable or purely additional. (shrink)
In this paper I argue that equal respect-based accounts of the normative basis of tolerance are self-defeating, insofar as they are unable to specify the limits of tolerance in a way that is consistent with their own commitment to the equal treatment of all conceptions of the good. I show how this argument is a variant of the longstanding ‘conflict of freedoms’ objection to Kantian-inspired, freedom-based accounts of the justification of systems of norms. I criticize Thomas Scanlon’s defence of ‘pure (...) tolerance’, Anna Elisabetta Galeotti’s work on the relationship between tolerance, equal respect and recognition, and Arthur Ripstein’s recent response to the ‘conflict of freedoms’ objection. The upshot of my argument is that, while valuing tolerance for its own sake may be an appealing ideal, it is not a feasible way of grounding a system of norms. I close with a thumbnail sketch of two alternative, instrumental (i.e. non- Kantian) approaches to the normative foundations of tolerance. (shrink)
I argue that a concept is applied correctly when it is applied to the kind of things it is the concept of. Correctness as successful kind-tracking is fulfilling an externally and naturalistically individuated standard. And the normative aspect of concept-application so characterized depends on the relational (non-individualistic) feature of conceptual content. I defend this view against two objections. The first is that norms should provide justifications for action, and the second involves a version of the thesis of indeterminacy of reference.
This paper focuses on one of the original moments of the development of the “phenomenological” current of psychiatry, namely, the psychopathological research of Ludwig Binswanger. By means of the clinical and conceptual problem of schizophrenia as it was conceived and developed at the beginning of the twentieth century, I will try to outline and analyze Binswanger’s perspective from a both historical and epistemological point of view. Binswanger’s own way means of approaching and conceiving schizophrenia within the scientific, medical, and psychiatric (...) context of that time will lead us to grasp the epistemological stakes at the origins of his project of reforming psychiatry by means of phenomenology. I will finally attempt to upgrade and update Binswanger’s project in light of the current reappraisal of phenomenology within the ongoing debate on psychopathology engaged by studies in the field of science and philosophy of mind.

We aim to show that far-related primates like humans and the capuchin monkeys show interesting correspondences in terms of artifact characterization and categorization. We investigate this issue by using a philosophically-inspired definition of physical artifact which, developed for human artifacts, turns out to be applicable for cross-species comparison. In this approach an artifact is created when an entity is intentionally selected and some capacities attributed to it (often characterizing a purpose). Behavioral studies suggest that this notion of artifact is not (...) specific to the human kind. On the basis of the results of a series of field observations and experiments on wild capuchin monkeys that routinely use stone hammers and anvils, we show that the notions of intentional selection and attributed capacity appear to be at play in capuchins as well. The study also suggests that functional criteria and contextualization play a fundamental role in terms of artifact recognition and categorization in nonhuman primates. (shrink)
