Arts as a Pillar of Health
The empirical counterpart to the wiki's aesthetic argument: that engagement with the arts is measurably good for the body.
Art Cure makes a claim the wiki's philosophical sources gesture at but cannot prove: that sustained engagement with the arts belongs alongside diet, sleep, exercise, and nature as a pillar of health. The effects are measurable and adjusted — lower incidence of depression and dementia, lower blood pressure, a slower biological clock — and they are perishable: stop, and they fade.
Two Arguments, One Conclusion
This is the empirical face of the case the wiki makes elsewhere on aesthetic grounds. Where The Aesthetics of Music argues that the trained ear is a human good in itself, Art Cure shows that the same engagement is continuous with a longer and healthier life. The aesthetic and the epidemiological arguments hinge on the same point from opposite sides — which is why the wiki keeps them in view together, across Domain III — Music and Domain IV — Beauty.
