I started writing my first philosophical treatise yesterday night, after almost a decade of not occupying myself with purely philosophical works (i have a degree in Philosophy, but mostly write/think about literature).
Its topic (or at least that of the first chapter) is the relation between the notions of the external and the internal world.
Generally my starting point is that each person can be seen as an atom in the external world, but also that each Ego can be seen as an atom in the internal world. Thus there is a parallelism between the two.
Also there is the idea of space, which creates this characterization, and that idea too is argued to be both one that is found in the external, but also in the internal world: space is formed as a notion in part from the person's reaction to his eyesight and ability to move in a three dimensional space. Thus it is an anthropomorphic notion. But at the same time space is seemingly something that belongs to the external world, since its understanding makes the phenomenon of existing in an external world possible.
Furthermore there is the idea of speech, which is argued to be another parallel of the idea of moving in space, this time moving in thoughtful interaction with others. Speech gives us the ability to come into contact with other people in the mental plane, like having a physical body and the ability to move gives us the capacity to interact with others in the physical plane. Also speech is to be seen as a phenomenon which influenced the further development of Logos (thinking) while the appearance of Logos predates speech in human history and development.
Anyway, these are some of the points of the first chapter. I am currently at the third part of it (wrote almost 8 pages last night). I think that i would like to expand the treatise to at least 1000 pages, which is roughly how much i write in my diary in a full year, but this can be written a lot faster if i am consistent in creating it.
I would be very interested in reading your impressions of this general presentation of my study. You can comment on its topic, its specific characterization in this thread, or anything else that relates to it. I hope this can expand into a meaningful discussion, and, as Heidegger once wrote: "by discussing it becomes obvious what the original idea was about"
