Whether collective agency is a coherent concept depends on the theory of agency that we choose to adopt. We argue that the enactive theory of agency developed by Barandiaran, Di Paolo and Rohde (2009) provides a principled way of grounding agency in biological organisms. However the importance of biological embodiment for the enactive approach might lead one to be skeptical as to whether artificial systems or collectives of individuals could instantiate genuine agency. To explore this issue we contrast the concept (...) of collective agency with multi-agent systems and multi-system agents, and argue that genuinely collective agents instantiate agency at both the collective level and at the level of the component parts. Developing the enactive model, we propose understanding agency – both at the level of the individual and of the collective – as spectra that are constituted by dimensions that vary across time. Finally, we consider whether collectives that are not merely metaphorically ‘agents’ but rather are genuinely agentive also instantiate subjectivity at the collective level. We propose that investigations using the perceptual crossing paradigm suggest that a shared lived perspective can indeed emerge but this should not be conflated with a collective first-person perspective, for which material integration in a living body may be required.

Philosophical orthodoxy holds that Thomas Reid is an externalist concerning epistemic justification, characterizing Reid as holding the key to an externalist response to internalism. These externalist accounts of Reid, however, have neglected his work on prejudice, a heretofore unexamined aspect of his epistemology. Reid’s work on prejudice reveals that he is far from an externalist. Despite the views Reid may have inspired, he exemplifies internalism in opting for an accessibility account of justification. For Reid, there are two normative statuses that (...) a belief might satisfy, being blameless and having a just ground. Through reflection, a rational agent is capable of satisfying both of these statuses, making Reid an accessibility internalist about epistemic justification. (shrink)

We are ignorant knowers. This paper proposes an information theoretic explanation of that fact. The explanation is a conjunction of three claims. First, that even in those dimensions where we are capable of picking up information, there is information that we don’t pick up. Second, that there can be dimensions of information for which we lack the capacity to pick up any information whatsoever. Third, that we don’t know whether the faculties and cognitive capacities we are endowed with process all (...) the information that they pick up. (shrink)

This paper presents and defends a model of religious faith as an epistemic disposition. According to the model, religious faith is a disposition to take certain doxastic attitudes toward propositions of religious significance upon entertaining certain mental states. Three distinct advantages of the model are advanced. First, the model allows for religious faith to explain the presence and epistemic appropriateness of religious belief. Second, the model accommodates a variety of historically significant perspectives concerning the relationships between faith and evidence, faith (...) and volition, and faith and doubt. And, finally, the model offers an appealing account of what unifies religious faith with other kinds of faith. (shrink)

This paper answers two interpretive questions surrounding belief in God in Thomas Reid’s philosophy, the status question and the detachability question. The former has to do with the type of justification Reid assigns to belief in God – immediate or mediate. The later question is whether anything philosophically significant depends on his belief in God. I argue that, for Reid, belief in God is immediately justified and integral to some parts of his system. Reid’s response to skepticism about God is (...) more complicated and more interesting than many of the contemporary philosophers who, citing Reid as inspiration, also hold that belief in God enjoys immediate justification. In Reid’s hands the approach to belief in God does not compete with inferential justification, does not rely on a special faculty, and foregrounds the developmental character of his epistemology.

The present investigation concerns Reid’s explanation of how objects (be they real or nonexistent) are conceived. This paper shows that there is a deep-rooted tension in Reid’s understanding of conception: although the type of conception employed in perception is closely related to the one employed in imagination, three fundamental features distinguish perceptual conception (as the former will be referred to throughout this paper) from imaginative conception (as the latter will be called henceforth). These features would have been ascribed by Reid (...) himself to conception as involved in perception, but not to conception as involved in imagination. He should have recognized them as marking the former as a different kind from the latter, and he should not have hastily lumped perceptual and imaginative conceptions together. (shrink)

This dissertation concerns the location and nature of phenomenal qualities. Arguably, these qualities naively seem to belong to perceived external objects. However, we also seem to experience phenomenal qualities in hallucinations, and in hallucinations we do not perceive any external objects. I present and argue for a theory of the phenomenal qualities, "brain theory", which claims that all phenomenal qualities we experience are physical properties instantiated in the brain, regardless of whether they are experienced in veridical perceptions or in hallucinations. (...) I begin by more carefully identifying the phenomenal qualities, discussing how they are related to "qualia" and "phenomenal character". Then I present brain theory, and investigate its implications for the perceptual relations we stand in to external objects, noting that it is mostly neutral. I also compare brain theory to a similar theory of perception advocated by Bertrand Russell. Next, I provide an overview over the competing theories of phenomenal qualities, and relate them to theories of perception, such as representationalism, qualia theory, sense data theory and disjunctivism. The majority of my argumentation for brain theory focuses on arguing that the phenomenal qualities are instantiated in the brain, rather than on arguing that they are physical properties. Instead, I largely assume physicalism. However, even independently of the physicalism assumption, I show that we have reason to believe that phenomenal qualities are experienced in hallucinations, and that qualities experienced in hallucinations are instantiated in internal objects, such as our brains or sense data. In the first step towards this conclusion I argue that theories which deny that phenomenal qualities are experienced in hallucinations face serious problems. In the next step I argue that theories which deny that phenomenal qualities experienced in hallucinations are instantiated in internal objects face serious problems. Finally, an important part of the argumentation is my replies to objections against brain theory, including common sense objections and the "observation objection". From these conclusions, together with the physicalism assumption, I infer that we have reason to believe that brain theory is true about hallucinations. On this basis, I then argue, through a generalizing argument, that the same is the case for veridical perceptions. (shrink)

Na filosofia moderna, Thomas Reid (1710-1796) foi um dos filósofos que olhou com atenção para o problema da vagueza das palavras quando utilizadas para expressar nosso pensamento ao outro. Ao tratar da concepção de linguagem, Reid parece abordar o tema da ambiguidade e da vagueza das palavras de modo a afastar os erros que a linguagem carrega consigo, apurando-a no sentido de torná-la mais adequada à representação dos fenômenos mentais e, desta forma, tornar possível o avanço sobre o estudo acerca (...) da mente. O presente estudo busca tornar aparente a noção reidiana de linguagem, pretendendo, assim, expor o que esta noção pode representar no que diz respeito à relação entre mundo perceptível, mente e linguagem a partir do pensamento de Reid.
