In this paper, I present the discussion between Ayer and Austin about whether sentences or utterances can be incorrigible and I argue in favor of Austin position. I defend Austin against objections from Ayer presented after the publication of Sense & Sensibilia. Unlike what was sustained by Ayer, experiential sentences and material object sentences are not epistemically asymmetrical. A material object sentence can be incorrigible if uttered in appropriated circumstances, and an experiential sentence can be corrigible if uttered in unappropriated circumstances. Relying on Austin position, I argue that self-knowledge does not have any epistemic privilege in relation to knowledge of the external world. These kinds of knowledge equally depend on objective circumstances of the utterance situation.

In this paper, I argue that the ecological approach to perception provides resources to overcome the causal argument against disjunctivism. According to the causal argument, since the brain states that proximally cause the perceptual experience and the corresponding hallucinatory one can be of the same type, there would be no good reason to reject that the perceptual experience and the corresponding hallucinatory experience have fundamentally the same nature. Disjunctivism concerning the nature of the experience would then be false. I identify three assumptions that support the causal argument: the indistinguishability assumption, the linearity assumption, and the duplication assumption. According to the ecological approach to disjunctivism, these assumptions should be rejected, opening up room for a version of disjunctivism that I call 'Ecological Disjunctivism'. Perceptual episodes are extended over time and are supervenient to the organism-environment system. They can be distinguished from the 'corresponding' hallucinations because the former results from a controlled process of attunement to the environment, whereas hallucinations are passive and insensible to the exploratory activities of the perceptual system. Finally, ecological disjunctivism, since it is immune to the causal argument, is more advantageous than negative and positive disjunctivism.

The foundationalist needs to deal with two fundamental problems: (i) to explain how a justificator grants justification without itself need justification and (ii) to determine the justificator’s epistemic status. Burdzinski (Burdzinski 2007), following Sellars and Bonjour, argues that the perceptive experience could not be a response to the first problem, because if its content was not propositional it would not grant justification and if its content was propositional it would grant justification and would require justification. My proposal is that perceptual experience justifies in virtue of its representational nature. The act of taking the content of a perception by its face value is justified until there is a reason to the contrary, ie, this act is prima facie justified. This forces us to answer the second problem by saying that the basic justificator is not infallible. This falibilist response dislike the skeptic, but it is the best foundationalist answer to epistemic regress.

A ideia de que a ciência — ou ao menos as atividades científicas que são consideradas as mais essenciais para a ciência — deve ser livre de valores é bastante difundida. Neste capítulo, vou discutir essa tese, normalmente entendida como um ideal de ciência. Na primeira seção, introduzo alguns conceitos e distinções que são importantes para entender essa tese, como a diferença entre valores cognitivos e não-cognitivos. Na segunda seção, discuto o papel dos valores na seleção de problemas e na metodologia científica. Na terceira seção, apresento dois argumentos canônicos contra o ideal da ciência como livre de valores: o argumento da lacuna explicativa, de Helen Longino (1990), e o argumento do risco indutivo, de Heather Douglas (2009). Na quarta seção, discuto algumas respostas a esses argumentos. Por fim, na última seção, a partir da abordagem ecológica, exploro e sustendo a ideia de que a reconcepção da ciência como uma atividade social situada e adaptativa supera a dicotomia entre fato e valor que subjaz a discussão. Essa nova concepção de ciência nos permite acomodar melhor os resultados dos argumentos apresentados na terceira seção.

Our goal in this paper is to discuss the notion of animal knowledge in Judgment and Agency. Our approach has two stages. First, we offer a positive contribution, attempting to show that there is room for the introduction of emotions into an animal knowledge approach and into Sosa’s theory of competence. If we follow Sosa and conceive knowledge as a kind of action or successful performance, then emotions can contribute functionally for enhancing performance and are essential for the sharing of knowledge among social agents. Second, we offer criticism of Sosa’s integrative project. It’s not clear that reflective knowledge always improves animal knowledge; rather, in order to avoid regress, Sosa should recognize that we can have perfectly safe animal knowledge. Finally, we argue that reflective knowledge has a more marginal role than Sosa seems at first sight to suggest.

The aim of this paper is to present an explanation of how perceptual experience fulfills its role of justification. The idea is that perceptual experience justifies non-inferentially empirical beliefs in an internalist sense of justification. Against Sellars, I want to say that S relied on his experience to believe that the world is so and so. To discuss this question, I choose the arguments of Brewer and McDowell. Both argue that theexperience can justify beliefs, provided it has a conceptual content. But I will defend that there is no such need. The content can be non-conceptual and even so the experience can justify beliefs non-inferentially. I will try to explain how this is possible and at the end I will assess my approach in the face of Sellars' claim that empiricism assumes a triad of inconsistents thesis. I will recast these thesis in accordance with the approach defended and I will conclude that this present version of empiricism is free from Sellars's criticism.
