Beauty is just one possible goal—not a requirement.
Many great works pursue truth, ugliness, chaos, violence, absurdity, conceptual shock, political rage, or pure formal experiment instead.If "beauty" is defined narrowly as pleasing, harmonious, decorative aesthetics, then a large part of modern and contemporary art deliberately rejects it.
What matters more is whether the painting has intensity, honesty, necessity, or a new way of seeing.Beauty can be present, but it can also be refused, subverted, or simply irrelevant.Related links:
