Mine is Heraclitus, "the weeping philosopher". All we have of his writings are fragments, my favorite being:
He who hears not me but the Logos will say: All is one.
I have hope that with new archaeological discoveries, and with new technology being used to recover old, formerly unreadable documents like burnt paper which can now be read, that there will be more writings of the Pre-Socratics available for us to read in the future.
