Phenomenology and the Mind Body Question Saying the mind is a phenomenon has the advantage that no explanations for it are required. No need for a materialistic approach (calling it an illusion), no need for quantum mechanics, no need for invoking a holistic approach explaining it as a consequence of interaction, no need of any system of knowledge to embed it in to explain it. It takes the mind at face-value. To understand the mind, the phenomenological approach doesn't need such explanations. Thoughts and feelings are not framed within explanatory schemes about it.
For giving usefull aid to people with mental problems, an understanding is obviously required. And it's here that the PA is most usefull as one is not hindered by explanatory schemes to explain it.
What use is an approach which views the mind as an illusion emerging from complicated neural activity in the brain (an approach which might be an illusion itself), what use is this approach to a depressed person (and I can tell by experience that it's an be an all-consuming feeling, almost paralyzing even)? Is the person involved in need of an explanation of the mind?
Explanation isn't tantamount to understanding. Trying to solve the depression by giving medicines based on the materialistic approach, explaining depression as a disturbance of a balance of neurotransmitters between neurons and re-uptake of them, might have a value, like any materialistic approach to the feeling might have (cutting neuronal connections, administering drugs to get in a Prosacious state of mind, or even lobotomy), though there is no understanding involved. Just the observation that there is a depression, and that this can go away by intervening with it in the ways mentioned.
Now, this might be helpful to some. But the approach takes away the broader space in which the depression finds itself, and there are many complaints of patients that the depression even gets worse. I know for a fact that it did in my case. Luckily, in my case, the depression has evaporated by itself. Lobotomy might have done the trick, but I have the feeling my whole brain would had to be lobotomized from itself.
Phenomenology tries to understand from within. It's an attempt to understand from where the depression comes (and I use the depression here generically), an attempt to find the origins, and to free people from these origins or make them aware of them.
On this base, understanding a depression like in phenomenology, understanding the phenomenon from within and looking at its origins, people can be made aware of it and act accordingly.
Now this might overlook the true nature of a depression, as materialists or whoever tries to explain the mind in an explanatory scheme. For the people experiencing the depression this approach will not be very useful. Maybe temporary measures can help and give relief. It didn't in my case but it could.
An explanatory approach might be useful thus. There is no understanding though about the feeling of the depression, like it is impossible to know how it is to be a rat. But people (and animals, for that matter) have mental phenomena in common, and as such an understanding can be achieved. Trying to find out where a mental phenomenon originates is a powerful approach in dealing with mental disorders, and the materialistic approach usually is an attempt to look at a mental phenomenon as an independent state which can be analyzed and explained from the outside and can be altered or "dissolved" on the base of the analysis and the explanatory scheme. There is no attempt to an internal understanding and usually there is no attempt made to place the phenomenon in a broader context like the world in which the mental phenomena are embedded, which in the particular case of a depression might be indispensable.
