Abstract With some help from the commentators, a few adjustments to the characterizations of A-consciousness and P-consciousness can avoid some trivial cases of one without the other. But it still seems that the case for the existence of P without A is stronger than that for A without P. If indeed there can be P without A, but not A without P, this would be a remarkable result that would need explanation. 

The science of consciousness must include its more advanced forms

An understanding of high forms of consciousness is invaluable to the scientific study of consciousness and poses challenges to the passive frame theory, including the notions that conscious thoughts are not connected and that consciousness serves skeletomotor conflict only.

The Interstitial Pathways as the Substrate of Consciousness: A New Synthesis

In reviewing the wealth of studies of human consciousness since the mid-20th century, it concludes that many proposals for the particular neural substrate of consciousness are insufficient in various respects, but that the results can be integrated into a novel scheme that consciousness extends through a subcortical network of interlaminar structures from the brainstem to the claustrum.

Consciousness, semiosis, and the unbinding problem

Understanding Phenomenal Consciousness

Focusing on sensory experience and perception qualities to present a dualistic view of the mind (called Qualitative Event Realism), this book doesn't conform to the dominant materialist views. Its

The ant colony as a test for scientific theories of consciousness

It is suggested that the Ant Colony Test (ACT) can provide insight into the nature of consciousness, and highlight the ant colony as a model system for ethically performing clarifying experiments about consciousness.


Thomas Reid claims to share Locke's view that consciousness is a kind of inner sense. This is puzzling, given the role the inner-sense theory plays in indirect realism and in the theory of ideas

Empirical status of Block's phenomenal/access distinction

P/A (Block's phenomenal/access) confounds a logical distinction with an empirical claim. Success of P/A in its logical role has almost no bearing on its plausibility as an empirical thesis (i.e.,

This target article argues for an abstract solution to the problem and exhibits a source of empirical data that is relevant, data that show that in a certain sense phenomenal consciousness overflows cognitive accessibility and can be found a neural realizer of this overflow.

Continuity and the Flow of Time: A Cognitive Science Perspective

This chapter aims to provide an overview of functional consciousness and time perception in brains and minds, and to describe a computational cognitive architecture partially implementing these phenomena.

In the view advanced here, human consciousness constitutes the ultimate evolutionary transition by allowing agents to become autonomous with respect to their evolutionary priors leading to a post-biological Anthropocene.



A Reason for Doubting the Existence of Consciousness

I was asked, as a philosopher, to address an audience primarily of psychobiologists about the nature of consciousness. Many people—among them, quite likely, many readers of the present volume—might

A Thoroughly Empirical Approach To Consciousness

When are psychologists entitled to call a certain theoretical construct "consciousness?" Over the past few decades cognitive psychologists have reintroduced almost the entire conceptual vocabulary of

Is there a ghost in the cognitive machinery

Abstract The cognitive mind‐brain is haunted by the ghost of consciousness. Cognitive science must face this ghost, since consciousness is perhaps the most important mental phenomenon: it forms a

It is argued that the notion of conscious experience is a good candidate for denoting a distinct and scientifically interesting phenomenon in the brain, and data concerning deficits resulting from various types of brain damage strongly point to the hypothesis that conscious experience expresses information that is available for global, integrated, and flexible behavior.

Consciousness and the Computational Mind

In Consciousness and the Computational Mind, Ray Jackendoff develops an overview of the mental representations invoked by the language, visual, and musical faculties, and describes how they are used in perception, production, imagery, and thought.

A History of the Mind

The mind-body problem is widely seen as the great remaining challenge to science and philosophy. Why and how did matter evolve to take on the quality of mind? The author takes the reader to the edges

What is it like to be a Bat

Consciousness is what makes the mind-body problem really intractable. Perhaps that is why current discussions of the problem give it little attention or get it obviously wrong. The recent wave of

The Rediscovery of the Mind

The Nature of the Mind

Men have minds, that is to say, they perceive, they have sensations, emotions, beliefs, thoughts, purposes, and desires. What is it to have a mind? What is it to perceive, to feel emotion, to hold a
