So just as the medium is the message, the style is the sense.
And style, of course, is unconscious - it is very difficult to fake style.
So our style reveals our true self.
How interesting that MBTI is interested in style just when the Noosphere is making style visible.
MBTI gives us a way of talking about style - MBTI is a template of style.
Just as the internet is making the unconscious, conscious, MBTI comes along to help us order our new perceptions.
No wonder MBTI is so popular.
I would see it as the medium being just all the words--we share the same medium, in order to convey a certain message, and with it we happen to utilise a certain style. I don't think it's impossible for someone to try on very different styles ('fake' a style). People do so in such activities as creative writing projects--but I suppose in this context, on a sort of personal interest forum, what would be the purpose of trying to fake a style?
I agree that style does reveal aspects of the individual who utilises the style, if it is the one they are most comfortable with. But I imagine a chosen style can be at least two things: 1) an external expression of what is internal--in which case I feel it is possible to lose something in the translation of what is internal when trying to realise it in the external world, and 2) an attempt to create a specific image, or picture, or atmosphere of something--in this case it doesn't have to have anything to do with 'true' self, but something particular we want to convey.
So in a sense style can mean two different things. Yes it may reveal your self, but it may also be very detached from the self. I do think it is something you can fake--just look at fashion styles. People may choose to dress a certain way, just as they write a certain way, to express themselves. But they can also choose a style of dress that may not be congruent to their internal self.
Perhaps I have the idea all wrong, or your point all wrong, yet this is how I perceive it. I would say your writing style in particular seems to be one you are very comfortable with, so yes, it may reveal a portion of your self (but what do you mean by true self).
I have very little idea of what you are talking about with the MBTI and Noosphere connection to be honest. (I don't have much understanding of noological concepts except that it relates to the human mind I think.) And I mean, I only find MBTI a popular thing on this forum, and in some business interests, but I only recognize the use of MBTI in a very limited fashion outside of the discussion on this forum. I don't really see MBTI as a template of style--my understanding of it is that is is more like a framework of different values and perceptions that people tend to have. Characteristic communication styles also tend to come with these.
Eh.. I'm sorry this message is so long. When I am unclear about something I tend to go on and on so that perhaps someone may clarify me along the way or something like that. My 'style' is it?
