Never heard of this balldude. Just checked his site out of curiousity who the hell he is. I can't say it very much sparked me to read more of it or something. Rather just do the 5meo myself than pay someone 200bucks to talk about it.
Don't know if he's egotistic because i did't take that close a look at his site. It is a bit odd though that someone mentions his Phd like that, you seldom see people intruducing themselves that way. On the other hand: if he can convince enough people to pay him that much for just having a little chat to be able to make a living out of it, you could see it as some form of legitimisation of it. Like: enough people care to make it relevant or something.
But now the serious stuff about the symmetry...I would rather think that it's the fact that we are NEARLY symmetrical isntead of just a-symmetrical or symmetrical, that 'makes us human'.
I mean, in music you always see that expession comes from it sort of 'suggesting' a perfect harmonic, rhytmic, melodic and counterpunctual structure and then to deviate from that 'perfection'.
Deviations from the perfect scheme creates tensions because it litterally dissonates with your expectations, and emotion in music comes from the flow of tension in it's structure.
How it builds and releases.
You could say that everything that has no structure, no 'symmetry' in it at all could never have any tension in it, no emotion therefore, because it doesn't create any expectation, while everything that's perfectly symmetrical or just totally flawless in some other way cannot have any emotion in it either because it feels sterile; There's nothing that collides with what you expect and therefore there's no tension at all. No tension between deviating from the path and remaining the recognisable structure.
I guess that sort of tension is a key element in the symphonic masterpiece we call life.
I could be ranting about something totally different than pandorra and ball in their 5meo states have experienced though.
