This paper argues that normative claims are truth‐apt contents of cognition – propositions about what there is reason to believe, to do or to feel – but that their truth is not a matter of correspondence or representation. We do not have to choose between realism about the normative and non‐cognitivism about it. The universality of reasons, combined with the spontaneity of normative responses, suffices to give normative claims the distinctive link to a ‘convergence commitment’ which characterises any genuine judgement; (...) an accurate epistemology of normative discourse need postulate no faculty of receptivity to a special domain of normative fact. Some general arguments for the view that cognitivism about a domain of discourse imposes realism about it are considered and rejected. (shrink)

A new theory is taking hold in neuroscience. It is the theory that the brain is essentially a hypothesis-testing mechanism, one that attempts to minimise the error of its predictions about the sensory input it receives from the world. It is an attractive theory because powerful theoretical arguments support it, and yet it is at heart stunningly simple. Jakob Hohwy explains and explores this theory from the perspective of cognitive science and philosophy. The key argument throughout The Predictive Mind is (...) that the mechanism explains the rich, deep, and multifaceted character of our conscious perception. It also gives a unified account of how perception is sculpted by attention, and how it depends on action. The mind is revealed as having a fragile and indirect relation to the world. Though we are deeply in tune with the world we are also strangely distanced from it. (shrink)

This is a book about how we see: the environment around us (its surfaces, their layout, and their colors and textures); where we are in the environment; whether or not we are moving and, if we are, where we are going; what things are good for; how to do things (to thread a needle or drive an automobile); or why things look as they do.The basic assumption is that vision depends on the eye which is connected to the brain. The (...) author suggests that natural vision depends on the eyes in the head on a body supported by the ground, the brain being only the central organ of a complete visual system. When no constraints are put on the visual system, people look around, walk up to something interesting and move around it so as to see it from all sides, and go from one vista to another. That is natural vision—and what this book is about. (shrink)

"Perception is not something that happens to us, or in us," writes Alva Noe. "It is something we do." In Action in Perception, Noe argues that perception and perceptual consciousness depend on capacities for action and thought — that ...

Back in 1950, while a physics major at Harvard, I wandered into C.I. Lewis’s epistemology course. There, Lewis was confidently expounding the need for an indubitable Given to ground knowledge, and he was explaining where that ground was to be found. I was so impressed that I immediately switched majors from ungrounded physics to grounded philosophy.
