Apply the standard of "perspective always colors human perception of truth"?
Sure we do - doesn't (necessarily) mean 2+2 .ne. 4 however. The truth IS whatever is true, regardless of what we perceive.
Re: in their original language - oh boy, do I envy you. At this stage of the game, I simply begrudge the time it would take. AND, I am not at ALL sure it is necessary to know EVERY argument ever made by every philosopher in order to glean some good even from the thoughts of the lowliest of plebes that are actually living life.
Re: dictionaries - Unfortunately, we plebe's just gots to plow with the horses we got :-)
Platonic IDEAL may "exist", but that does not mean we will EVER be able to apprehend it. BUT my friend, the fun is all in the chasing (and occasional small findings) isn't it?
There are solid philosophy dictionaries, even on line. Just takes a bit of looking. Don't blame the "plebes", blame what "makes" them plebes!
I would LOVE to read YOUR interpretation of the consummation of philosophy to this point, have you written it yet?
lol, it's a work in progress . . .
