When I’m asked why I like an abstract painting I usually reply that I like the look of it. This is often not accepted as an answer, particularly if the questioner is not a fan of abstract art. I am usually then asked why I like the look of it. This does not happen when the conversation is about food. If I say I like cheese no-one ever asks me why. If they did I would simply say I like the taste of it. No-one would challenge that answer.
In other words, enjoying looking at something is not seen as believable, even though for me neither the enjoyment of looking at art nor the enjoyment of eating require explanation. Unless I come up with a verbal explanation of why I like looking at something I am seen as a fraud and abstract art as a hoax.

The truth is that explanations of why you like the look of something are like explanations of why you like the taste of something. They are false rationalisations. You may say that the colours are harmonious, the composition is balanced, this cheese has a nice texture,  but these are just describable attributes which we work out after the initial attraction. This initial attraction cannot be verbalised. Please stop asking me why I like the look of something.
It is not by accident that the word taste applies to art as well as food.
