[MA-VM-356]
USES OF SICKLINESS
He who is often ill not only has a far greater pleasure in health, on account of his so often getting well, but acquires a very keen sense of what is healthy or sickly in actions and achievements, both his own and others’. Thus, for example, it is just the writers of uncertain health—among whom, unfortunately, nearly all great writers must be classed—who are wont to have a far more even and assured tone of health in their writings, because they are better versed than are the physically robust in the philosophy of psychical health and convalescence and in their teachers—morning, sunshine, forest, and fountain.
