I feel like this thread is as good a time as any other to say that I have always been baffled by paintings.
They have almost never made me feel a deep emotion or sunk me in an abyss of contemplation and reverie. When I look at a painting, I just say, "OK, well-done" but don't feel anything if it's some Renaissance work with well-done anatomy, proportion, lighting, etc. And if it's something more modern, like a Picasso or Pollock, my inward mental and emotional reaction can be perfectly represented by:
"..."
I am almost literally "blind" to the merits of painting, they have almost never excited in me great thoughts or emotions or even awe at their aesthetic beauty.
However, one exception is Monet's water lilies. For some reason, they're the only things that strike me with awe. I can't even say why. And I am in general so uninterested in paintings from what I've seen of them (besides Monet's water lilies) that I can't be bothered to learn more about the history or fundamentals of painting. When I see or hear people talking about the awe paintings put them into, and talking about all the "technique" and the "theory" behind it, all I feel is nothing. I feel as if I'm watching robots mechanically jack themselves off in public.
In one sense, you could say that a lot of painting is "subjective", and that people see a merit in them that isn't there. My theory is that, as children or early teenagers, they became interested in drawing and painting for whatever reason, perhaps because they did good in art class. Then they learn more about art, and grow up to learn more about art, and, since children have very plastic minds, convince themselves from childhood that there is a deep value in painting. They read books on art criticism or read reviews of artists going into hysterics over the beauty of the artists, and these critics/reviewers/expositors have themselves been mechanically brought up in the same way to "appreciate" paintings. Since children are very naive and generally accept as truth what is given to them from great authorities (within certain bounds), if they read that such-and-such a painting and painter is supposed to be very beautiful, they artificially force in themselves a corresponding "emotion" of "Wow, this is beautiful!"
Over time, they mechanize themselves to create this seem hysteria over art that's claimed by the mainstream as being good; really, the reaction to the art isn't an "objective" reaction to some merit in the art, but something that comes within themselves, a certain capacity towards imagination and fantasy. This is why there are not too many agreeing interpretations of an artwork most of the time: it's entirely subjective and mixed with the viewer's own emotions. If you haven't hypnotized yourself from an early age to be interested in art, you feel nothing looking at it.
