This volume celebrates the life achievements of Jason W Brown, who, along with Jean Piaget, Heinz Werner, Alexander Luria and the Wurzburg school, has significantly contributed to the development of a process-based theory of brain/mind capable of challenging the currently fashionable modularist or cybernetic approaches to understanding human thought and feeling. As a paradigm, Brown's microgenetic theory is thus applicable in both brain science (where Brown was inspired by the pioneering work of Schilder and Pick) and the philosophy of mind (where the influence of Bergson, Whitehead, Cassirer, and Merleau-Ponty can be seen).Essays with a range of focus as wide as Brown's expertise have been collected in such diverse areas as neuropsychology (microstructure of action, symptomatology, neuro-rehabilitation, neurolinguistics, locationism), theoretical psychology (consciousness, hypnosis, morphogenesis, personality development, psychoanalysis, Buddhist psychology, mysticism), and philosophy of mind.
