Implicit knowledge, a term coined by Reber in 1965, is acquired independent of conscious attempts to learn, and generally without the capacity to communicate what has been acquired. One of the core assumptions of this argument is that implicit learning is a fundamental process, one that lies at the very heart of the adaptive behavioural repertoire of every complex organism. This is a highly readable account of the cognitive unconscious, focusing in particular on the problem of implicit learning.

First Minds: Caterpillars, 'Karyotes, and Consciousness presents a novel theory of the origins of mind and consciousness dubbed the Cellular Basis of Consciousness (CBC). It argues that sentience emerged with life itself. The most primitive unicellular species of bacteria are conscious, though it is a sentience of a primitive kind. They have minds, though they are tiny and limited in scope. Hints that cells might be conscious can be found in the writings of a few cell biologists but a fully developed theory has never been put forward before. Other approaches to the origins of consciousness are examined and shown to be seriously or fatally flawed, specifically approaches based on: (a) the assumption that minds are computational and can be captured by an Artificial Intelligence, (b) efforts to discover the neuro-correlates of mental experiences and, (c) looking for consciousness in less complex species by identifying those that have precursors of those neuro-correlates. Reber shows how each of these approaches is shown to be either essentially impossible (the AI models) or so burdened by philosophical and empirical difficulties that they are effectively unworkable. The CBC approach is developed using standard models of evolutionary biology. The remarkable repertoire of single-celled species that micro- and cell-biologists have discovered is reviewed. Bacteria, for example, have sophisticated sensory and perceptual systems, learn, form memories, make decisions based on information about their environment relative to internal metabolic states, communicate with each other, and even show a primitive form of altruism. All such functions are indicators of sentience. Finally, the implications of the CBC model are discussed along with a number of related issues in evolutionary biology, philosophy of mind, the possibility of sentient plants, the ethical repercussions of universal animal sentience, and the long-range impact of adopting the CBC stance.

All species, extant and extinct, from the simplest unicellular prokaryotes to humans, have an existential consciousness. Without sentience, the first cells that emerged some 4 billion years ago would have been evolutionary dead-ends, unable to survive in the chaotic, dangerous environment in which life first appeared and evolved. In this book, Arthur Reber's theory, the Cellular Basis of Consciousness (CBC), is outlined and distinguished from those models that argue that minds could be instantiated on artificial entities and those that maintain consciousness requires a nervous system. The CBC framework takes a novel approach to classic topics such as the origin-of-life, philosophy of mind, the role of genes, the impact of cognition, and how biological information is processed by all species. It also calls for a rethinking of a variety of issues including the moral implications of the sentient capacities of all species, how welfare concerns need to be expanded beyond where they currently are, and critically, how all life is intertwined in a coordinated cognitive ecology. The Sentient Cell explores this revolutionary model, which updates the standard neo-Darwinian framework within which current approaches operate and examines the underlying biomolecular features that are the likely candidates for the "invention" of consciousness and outline their role in cellular life.

The term 'Implicit Learning' refers to the way in which knowledge of fairly complex, patterned material can be acquired without any conscious effort to learn it and with little to no awareness of what has been learned. Over the past fifty years, Implict Learning has became a vigorously researched area in the social sciences. In The Cognitive Unconscious, Arthur S. Reber and Rhianon Allen bring together several dozen experts from social science and neuroscience to present a broad overview of the exploration of the cognitive unconscious. Each chapter delves deeper into a subject that has become an interdisciplinary domain of research to which contributions have been made by sociologists, neuroscientists, evolutionary biologists, linguists, social and organizational psychologists, and sport psychologists, amongst many others. The book shows that unconscious, implicit cognitive processes play a role in virtually everything interesting that human beings do. As the contributors demonstrate, the implicit and explicit elements of cognition form a rich and complex interactive framework that make up who we are. With contributions from over thirty distinguished authors from nine different countries, The Cognitive Unconscious gives a balanced and thorough overview of where the field is today, over a half-century since the first experiments were run.
