What we see in art is of our choosing. Appreciation is recognizing the skills of the artist. We don't have to like it to appreciate it. We might pause to implore beauty to expose itself. When it fails to do so we might reject the art first hand. Or we can allow the art to stare back at us, allowing more to be revealed.
Art is manipulative. The more we absorb ourselves in its innate nature the more we feel the effects of our appreciation. Art is often assumed to be easy. The very fact that not everyone can create art is proof enough that there is some labor involved, some understanding of human nature, a degree of compromise, of recognition, of persistence.
Appreciation isn't for everyone. It requires knowledge. We need to know what is involved, what the artist intended, the context of the ideas. We don't always have the time to devote to art.
Make time: just once.
