What do pictures need ? A material support, a bodily medium, and a place to be seen.
What do they demand? To be looked at, to be admired, to be loved, to be shown.
Art works signal the possibility of the non-existent; their reality testifies to the feasibility of the unreal, the possible.
Richard Feynman
W.J.T. Mitchell, What do pictures want ?
The worthwhile problems are the ones you can really solve or help solve, the ones you can really contribute something to. ... No problem is too small or too trivial if we can really do something about it.
It is a tale told by an idiot, full of sound and fury, signifying nothing.
Shakespeare, The tragedy of Macbeth, Scene V.
