Zoe Drayson: The Philosophy of phenomenal consciousness Philosophy of Mind – Prof. Dr. phil. Sven Walter – Wednesday 8 am Jakob Lohkamp CQ1: On p. 277, Drayson says: “Science deals in data that are public in the sense of being shareable and measurable by others; the privacy of conscious experiences seems to prevent them fulfilling these criteria.” Why is that? Science is making great advancements in the research of consciousness, f.e. we now know how our eyes together with attention form our conscious perception of the world (Drayson 2015, p. 274ff.). Furthermore, we know how pain works on a neurological level, and are able to measure consciousness in other animals by conducting behavioural studies, where animals explore the mirror-image of themselves, enacting in self-reflective thought. These examples share one common trait, that for science we need observable, third person data that is replicable and . But, according to Drayson (2015, p. 275ff.) there is another aspect of consciousness in addition to its causalfunctional role, namely its phenomenal properties, which science fails to capture. Phenomenal aspects are characterized by experiential qualities, they do not enter our everyday lives, nor can they become the object of our introspection. What she refers to, also known as qualia, is partly explained in Thomas Nagel´s famous bat example, which in a nutshell states that we can not imagine what it feels like to be a bat, as being a bat has a quality to itself that only a bat can experience (Nagel, 1974). How do we know what we are talking about when referring to linguistic term X? We do not know it. We assume the other person will understand us from the basis of shared experience, but we can never be sure about it (Drayson 2015, p. 277). Qualia are subjective, inherently private and we need special access to them i.e. being a bat. According to Drayson (2015, p. 277 ff.) it is the subjectivity and privacy that we can not measure scientifically, leaving us unable to know for certain what it is like to experience the world through the mind of someone else. DQ2: On pp. 278–279, Drayson says: “Furthermore, it’s hard to see how the third-person scientific evidence could ‘trump’ my first person knowledge of my experience: what sort of evidence could a doctor use to persuade you that you’re in pain, when you are awake and conscious but not consciously experiencing pain?” Suppose this is plausible. Even then, does it hold for all mental states? Can’t we be mistaken about our own mental states in the sense that, say, a psychotherapist 1 might convince us that what we took to be an instance of, say, jealousy is in fact an instance of narcissism? I do believe that we can be wrong about our own mental states, which does not mean that I can be easily convinced of being in pain as in Drayson´s example. We certainly have introspection and are able to identify mental states we experience, especially mental states with high impact such as being in pain, fear or affection. In another exemplary mental state, depression, I believe one does not necessarily know that they are depressed. But as scientists learned more about the pathology of the disease, it was found that depression is often linked with hormonal imbalance in the brain, so it can be measured by medical staff, as well as behavioural descriptions. Furthermore, you may find yourselves looking back and acknowledging the mental state you have been through, again diminishing the chance of accurate introspection. Perhaps, in such a special case, only the change of mental states allows this kind of retrospection, . I believe, the more we learn about psychology and our functioning, we can see scientifically established, converging patterns in behaviour, and therefore mental states. As in the case of narcissism, I believe we can derive core traits of a person with this diagnosis, by checking for several pathological markers. Jealousy, as stated in DQ2, could be one of them. Still, it is unclear how well the definition will fit one´s character, as humans are rather complex. But psychologists and neurologists may be able to give an educated guess. Probably, the person affected will deny such a diagnosis, as it is linked with societal classifications, rendering one a good or bad member of society, as I would argue is the case for a lot of mental states. Lastly, if Qualia can not be measured, nor compared, how can we know that we do not share a great amount of it? We may never be able to fully understand one another but populations share an immense amount of experiences and knowledge about the world, which allows for subjective as well as inter-subjective exchange. It is this common ground that we rely on every day when using language and interacting with each other, as it would be impossible without it. Personally, I would not be easily convinced by a doctor to be in pain, but perhaps I will be convinced after all. 2 References Drayson, Zoe (2015).
