Thanks to R. Paul for his thoughtful reply on Greek thought on opposites, negation, etc. Among other things, he writes: >sleeping waking comes (waking and sleeping are >'opposites') -- one cannot learn one of >them without understanding that it is opposed to the other. Mmm. Depends on your perspective. Fish, for example, don't actually 'sleep' (at least they don't close their eyes). Therefore, I don't think they _have_ a concept of _sleeping_. Unless they see an oyster, who is _always_ sleeping?
