Opposites

Watching Touch the Sound and listening to Evelyn Glennie answer the question, "what is the opposite of sound?" got me to thinking about opposites. Glennie states,

The opposite of sound definitely isn’t silence . . . I don’t know if there is such a thing. Well, there must be an opposite actually, but what it is I don’t know . . . it’s the closest thing I can imagine to death.

What about other opposites, e.g., the opposite of love isn't hate, it's indifference because hate implies a sense of caring about the end product of something, just as love does. Also to consider is the Jewish theologian Martin Buber who frames the love and hate "opposites" as an "I and Thou" (which is also the name of the book from which I draw this quote).

So long as love is "blind," that is, so long as it does not see a whole being, it is not truly under the sway of the primary word of relation. Hate is by nature blind. Only a part of a being can be hated. He who sees a whole being and is compelled to reject it is no longer in the kingdom of hate, but is in that of human restriction of the power to say "Thou." He finds himself unable to say the primary word to the other human being confronting him. This word ["Thou"] consistently involves an affirmation of the being addressed. He [who hates] is therefore compelled to reject either the other or himself.... Yet the man who straightforwardly hates is nearer to relation than the man without hate and love.

I.e., one understanding of something can be that a full understanding does not come without understanding of the opposite, and, a partial understanding is more enmeshed in knowledge than nothing.

So I was thinking it would be interesting to do a cross media study of opposites. Thoughts?
