    opened things up further. But it was nearly three decades before the sudden
    explosion of interest in consciousness in the 1990s.
    From around the 1950s to the 1990s the ‘first-generation’ cognitive sciences had
    conceived of the mind in terms of abstract, language-like representations (Lakoff
    and Johnson, 1999, pp. 77–78) and relied heavily on analogies with digital com-
    puters, but increasingly people began to think more in terms of interconnected
    networks that change over time. From this connectionist approach came the idea
    of the neural network, which revolutionised the study and creation of artificial
    intelligence (see Chapter 12). This movement, along with the embodied philoso-
    phy of Merleau-Ponty, contributed to the emergence of the ‘second generation’ of
    cognitive science, which recognised that brains are always found in bodies, and
    bodies in environments – both physical and social.
    And thinking about cognition as ‘4E’ (Menary, 2010)  – as embodied, enactive,
    embedded, and extended (involving other objects and people in the environ-
    ment)  – opens up much more space for experience than does a computational
    brand of cognitivism. As the authors of The Embodied Mind put it: in the embodied
    paradigm, ‘cognition and consciousness – especially self-consciousness – belong
    together in the same domain. Cognitivism runs directly counter to this conviction
    [. . .] for cognitivists, cognition and intentionality (representation) are the insepa-
    rable pair, not cognition and consciousness’ (Varela et al., 1991, p. 173). Thinking
    about the kinds of experience that come from having a body with particular
    sensory and motor capacities, and from the feedback between these capacities
    and the environment, gives us an alternative to trying to uncover consciousness
    through the neurons alone.
    An approach that combines the insistence on feedback between brain, body,
    and world with a firm basis in brain function is that of predictive processing, the
    idea that brains are essentially prediction machines, constantly trying to match
    incoming sensory inputs with their own expectations or predictions (Clark, 2013).
    This is a modern version of Helmholtz’s idea of ‘unconscious inference’ and British
    psychologist Richard Gregory’s (1966/1997) much later notion that perceptions
    are guesses, or hypotheses, about the world. The difference is that with advances
    in neuroscience and computation we can begin to work out how the embodied
    brain builds its predictions and adapts the body’s responses to the world.
    Dynamics-based paradigms like this give us challenging new ways of thinking
    about the status of the brain in relation to the mind and consciousness, which we
    will return to in Chapter 3. In principle, they also link to other theories that stress
    the contexts of consciousness, such as social constructionism, a movement which
    built on the developmental psychology of the Soviet psychologist Lev Vygotsky
    in the 1930s, and which investigates how reality as we know it is constructed
    through social interactions. They have certainly begun to generate resonances
    within cognitive approaches to the study of literature (Caracciolo and Kukkonen,
    2014). But in practice, the methods and questions of 4E and predictive processing
    have not yet tended to expand very far into the study of language, history, and
    culture.


Even now, after centuries of philosophical and psychological inquiry, our under-
standing of how behaviour and ‘introspection’ relate to consciousness leaves a lot
to be desired (Costall, 2006), and even a definition of consciousness that everyone
