This chapter explains how mindmelding — the direct experience by one person of another's conscious states — is in fact possible. The temporal lobes causally interact with the prefrontal lobes by way of fiber bundles that run underneath the cortical surface. This provides the perfect first experiment in mindmelding: to ‘branch’ those fiber bundles and run the other end into the brain of another person. Evidence is provided that these bundles have close connections to consciousness, in that whatever (...) affects them has immediate effects on consciousness. Then, before responding to several objections, the chapter considers another issue brought up by these experiments — the question of the relation between mindmelding and mindreading. Is mindmelding similar to mindreading? Does the existence of a mindreading system help us achieve mindmelding? (shrink)

This chapter shows that mindmelding is metaphysically possible, i.e., that it does not violate any laws governing the metaphysical nature of reality. Metaphysical issues are fundamental and lie at the core of the most difficult parts of the problems of privacy and the mind-body problem itself. There is nothing stopping us from placing the idea of mindmelding on clear, unproblematic, and plausible metaphysical foundations. It is argued that the position of privacy is the one on shaky metaphysical grounds. (...) Two metaphysical theses are examined: the thesis of privacy, and the idea that all conscious states must have a subject, which is called ‘inseparability’ because it posits that the subject is inseparable from the conscious state.

This chapter presents the following hypothesis: There is a perfectly sensible conception of the mind, consciousness, the self, what we mean by ‘I,’ how we perceive and know, and how we remember and decide, all of which cohere amongst one another as well as with what we know about the brain, according to which it is possible for one person to experience directly the conscious states of another person. Not only can one person be directly aware of the conscious states (...) of another person, he can be more aware of them than their original owner. He can even be aware of them when their original owner will never be aware of them. Mindmelding is possible, and this possibility removes much of the force from the mind-body problem by removing the impasse caused by the belief in privacy. It removes what some philosophers saw as a need to posit strange metaphysical categories. The subject's sense of self can be separated from the object of her conscious awareness which can be bound to another's sense of self. (shrink)

[This download contains the Table of Contents and Chapter 1]. I argue here that the claim that conscious states are private, in the sense that only one person can ever experience them directly, is false. There actually is a way to connect the brains of two people that would allow one to have direct experience of the other's conscious, e.g., perceptual states. This would allow, for instance, one person to see that the other had deviant color perception (which was masked (...) by correct linguistic practice). This could be achieved by connecting one person's set of executive processes (or cognitive control network) to the conscious perceptual states of the other. Chapter 5 contains an internalist physicalist account of color according to which colors exist only as brain states. Their function is to enable more precise causal interactions between the executive processes and the brain's perceptual systems. This in turn allows for more precise action: I can select the red apples and leave the green ones. (shrink)

Contrary to the widely-held view that our conscious states are necessarily private (in that only one person can ever experience them directly), in this paper I argue that it is possible for a person to directly experience the conscious states of another. This possibility removes an obstacle to thinking of conscious states as physical, since their apparent privacy makes them different from all other physical states. A separation can be made in the brain between our conscious mental representations and the (...) executive processes that manipulate them and are guided by them in planning and executing behaviour. I argue here that these executive processes are also largely responsible for producing our sense of self in the moment. Our conscious perceptual representations themselves reside primarily in the posterior portions of the brain's cortex, in the temporal and parietal lobes, while the executive processes reside primarily in the prefrontal lobes. We can imagine an experiment in which we sever the association fibers that connect the posterior regions with these prefrontal regions and, instead, connect the posterior regions to the prefrontal regions of another person. According to my hypothesis, this would produce in the latter person the direct experience of the conscious perceptual states of the first person. (shrink)
