2nd presentation in the 2nd library, some hours ago..
Well.. it was ok, probably slightly better than the first presentation there, and probably a bit less interesting (for the people there) than my second presentation in the first library (with a different subject then; the Milesians), last week.
Mainly due to:
-I ended up only researching/creating the main piece for the presentation in 1 1/2 days. Mostly out of boredom but also the sense that i already had enough to present and i am sort of used by now to speaking to a crowd (the latter is true, i had no problems presenting, but the material was sub-optimal this time)
-The presocratic philosophers this time were only the Eleatics (Xenophanes, Parmenides, Zeno) and little has survived from their work (a few sentences from the first, 130 poem lines from the second, 9 paradoxes and some epigrams from the third).
-The main centers of the Eleatic thought are less easy to present in an hour, to such a crowd (around 20-25 people, but not of a common educational background or known background in philosophy anyway), cause the main eleatic ideas are far more 'mystical' than the ionian ones presented in the previous seminar. Basically some strange stuff about a united, unchanged 'Oneness' of a universe/god, which is in the shape of a sphere cause it extends equally to all directions since it is pretty much self-sufficient and has nothing around it but an undefined space (ie it is not infinite in space, since it has something around it, but it is still argued to be infinite in layers).
-The biggest problem was (i knew it would be) that the eleatics were regarded as of huge importance in the Socratic era. For example Plato named Parmenides as the father of the Socratic/Platonic ideas. Furthermore Democritos wrote his (massive, supposedly, but little remains) work as a direct contrast to the Eleatic idea of "nothingness" and also the famous notion of "vacuum" ("κενό"). So i tried a bit to present the infinite sets which when added lead to a specific limit to something (eg 1+ 1/2 + 1/4 + 1/8 +... almost equals 2, but only in an infinite parts of the progression, so is a limit, not something stable), cause it served as a basis to juxtapose the Zenonian idea of an impossibily of stopping infinite division of space, to the Democritian idea of the "Atom", which literally meant "un-divisible", and was proposed exactly so as to stop the division of something (eg matter) at a set point, so as to cancel the eleatic theory that due to infinite layers of divided mass there can only be one stable existence, for if anything actually changed then that would require the sub-parts to also be definitely changing at some set (even at an abyss) point in the division.
But yeah, it is somewhat impossible to present this crucial issue in presocratic philosophy (start of the 5th century now) without at least using examples from Archimedes and his own use of the notion of infinity, around two centuries later (but he famously was providing examinations on Zeno's paradoxes).

So, overall, i was not happy with the presentation today. I am always friendly there, and the people seem decent too, but it is very unrealistic to present this "overview of pre-socratic philosophy" in 4 1-hour meetings. I know that, and i also discussed this with them, and also i was unhappy that i sort of half-did the thinking on the presentation of the actually crucial notion of infinite divisions, but whatever, the task cannot really be approached in a very much more ambitious manner, not in 4 hours, and not in a library setting..
So i guess i am ok with that, although i will try to do a better job in the two (times 2) next meetings of this circle
