I love to eat, even though it is easy for me not to eat (when no one feeds me, when there is no food around). - Susan Sontag

Psychological theories of illness are a powerful means of placing the blame on the ill. Patients who are instructed that they have, unwittingly, caused their disease are also being made to feel that they have deserved it.

Dissimulation, secretiveness, appear a necessity to the melancholic. He has complex, often veiled relations with others. These feelings of superiority, of inadequacy, of baffled feeling, of not being able to get what one wants, or even name it properly (or consistently) to oneself — these can be, it is felt they ought to be, masked by friendliness, or the most scrupulous manipulation.

Any important disease whose causality is murky, and for which treatment is ineffectual, tends to be awash in significance. First, the subjects of deepest dread (corruption, decay, pollution, anomie, weakness) are identified with the disease. The disease itself becomes a metaphor. Then, in the name of the disease (that is, using it as a metaphor), that horror is imposed on other things. The disease becomes adjectival. Something is said to be disease-like, meaning that it is disgusting or ugly.
