Questioning Consciousness brings together neuroscientific, psychological and phenomenological research, combining in a readable format recent developments in image research and neurology. It reassesses the mind-body relation and research on 'mental models', abstract concept formation, and acquisition of logical and apparently 'imageless' inference skills. It is argued that to be conscious of an object is essentially to imagine in a habituated way what would happen if we were to perform certain actions in relation to the object; and that mental images fit together to build up abstract concepts. This analysis shows why conscious information processing is so structurally different from ― yet interrelated with ― non-conscious processing, and how mind and body interrelate as a process to its substratum in the way that a sound wave relates to the medium through which it passes.
