study in water

+++

Well, after this, said Socrates, when I was worn out with my physical investigations, it occurred to me that I must guard against the same sort of risk which people run when they watch and study an eclipse of the sun; they really do sometimes injure their eyes, unless they study its reflection in water or some other medium. I conceived of something like this happening to myself, and I was afraid that by observing objects with my eyes and trying to comprehend them with each of my other senses I might blind my soul altogether. So I decided that I must have recourse to theories, and use them in trying to discover the truth about things.
