Perceptually secured knowledge consists of beliefs that amount to knowledge just because they are based on suitable perceptual states. Relationism about the ground of perceptually secured knowledge is the view that if a perceptual state can make a belief based on it amount to knowledge, then it can do that because it constitutes an appropriate kind of relational state, e.g., a state of perceptual acquaintance. I explore the prospects of both maintaining that some beliefs amount to perceptually secured knowledge and developing a relationist account of their ground.

Phenomenology is about subjective aspects of the mind, such as the conscious states associated with vision and touch, and the conscious states associated with emotions and moods, such as feelings of elation or sadness. These states have a distinctive first-person ‘feel’ to them, called their phenomenal character. In this respect they are often taken to be radically different from mental states and processes associated with thought. This is the first book to fully question this orthodoxy and explore the prospects of cognitive phenomenology, applying phenomenology to the study of thought and cognition. Does cognition have its own phenomenal character? Can introspection tell us either way? If consciousness flows in an unbroken ‘stream’ as William James argued, how might a punctuated sequence of thoughts fit into it? Elijah Chudnoff begins with a clarification of the nature of the debate about cognitive phenomenology and the network of concepts and theses that are involved in it. He then examines the following topics: • Introspection and knowledge of our own thoughts • Phenomenal contrast arguments • The value of consciousness • The temporal structure of experience • The holistic character of experience and the interdependence of sensory and cognitive states • The relationship between phenomenal character and mental representation -/- Including chapter summaries, annotated further reading, and a glossary, this book is essential reading for anyone seeking a clear and informative introduction to and assessment of cognitive phenomenology, whether philosophy student or advanced researcher. It will also be valuable reading for those in related subjects such as philosophy of mind, philosophy of psychology and epistemology.

“The Epistemic Significance of Perceptual Learning” defends the view that perceptual experiences generate justification in virtue of their presentational phenomenology, preserve past justification in virtue of the influence of perceptual learning on them, and thereby allow new beliefs formed on their basis to also be partly based on that past justification. “The Real Epistemic Significance of Perceptual Learning” mounts challenges to these three claims. Here we explore some avenues for responding to those challenges.

By a reasoned change in logic I mean a change in the logic with which you make inferences that is based on your evidence. An argument sourced in recently published material Kripke lectured on in the 1970s, and dubbed the Adoption Problem by Birman (then Padró) in her 2015 dissertation, challenges the possibility of reasoned changes in logic. I explain why evidentialists should be alarmed by this challenge, and then I go on to dispel it. The Adoption Problem rests on a failure to distinguish between logical principles such as Universal Instantiation and Modus Ponens which might or might not govern your inferences with superficially similar laws which must govern your cognitive architecture.

According to proponents of irreducible cognitive phenomenology some cognitive states put one in phenomenal states for which no wholly sensory states suffice. One of the main approaches to defending the view that there is irreducible cognitive phenomenology is to give a phenomenal contrast argument. In this paper I distinguish three kinds of phenomenal contrast argument: what I call pure—represented by Strawson's Jack/Jacques argument—hypothetical—represented by Kriegel's Zoe argument—and glossed—first developed here. I argue that pure and hypothetical phenomenal contrast arguments face significant difficulties, but that there is a sound glossed phenomenal contrast argument for irreducible cognitive phenomenology.
