This paper considers how cognitive architecture impacts and constrains the rational requirement to respond to reasons. Informational encapsulation and its close relative belief fragmentation can render an agent’s own reasons inaccessible to her, thus preventing her from responding to them. For example, someone experiencing imposter phenomenon might be well aware of their own accomplishments in certain contexts but unable to respond to those reasons when forming beliefs about their own self-worth. In such cases, are our beliefs irrational for failing to (...) respond to our own reasons? Or are they excused on grounds of the reasons’ inaccessibility? I argue that in such cases, the rational status of the belief that fails to respond to reasons is modulated by the degree of encapsulation of the system that produces it. Yet because our cognitive systems are rarely perfectly encapsulated, our failures to respond to reasons are almost always irrational to some degree. (shrink)

Must reasons be able to feature in our deliberation? Proponents of a deliberative constraint on reasons endorse an affirmative answer to this question. Deliberative constraints enjoy broad appeal and have been deployed as premises in support of a variety of controversial philosophical positions. Yet, despite their uses, deliberative constraints have not received systematic philosophical attention. This entry aims to fill this gap in the literature. First, I sketch what's at stake in the debate over whether a deliberative constraint is true. (...) Then, I offer a taxonomy of the different versions of a deliberative constraint. Finally, I assess some of the arguments for and against a deliberative constraint. (shrink)

Perceptualism is a prominent theory analyzing emotions as perceptual experiences of value. A long-standing challenge to perceptualism says that emotions cannot be perceptual because they are subject to normative assessments in terms of reasons and rationality, while perceptual experiences are not. I defend perceptualism from this charge. My argument begins by distinguishing two forms of normative assessment: fundamental and non-fundamental. Perceptualism is compatible with the latter (i.e., non-fundamental reasons and rationality); even sensory experiences are so assessable. I next argue that (...) emotions are only non-fundamentally assessable. Following this argument, I outline a perceptualist-friendly theory of emotions as non-fundamentally normatively assessable.
