A man discouraged by a chronic illness remains able to enjoy his grandchildren and his hobbies. Why does this preserved enjoyment matter for distinguishing demoralization from a depressive illness?
The phenomenon's own text is explicit that demoralization and depressive illness are distinguished by pervasiveness, not severity of distress. Preserved enjoyment of unrelated areas of life — his grandchildren, his hobbies — is direct evidence that the low state has not spread pervasively, which is exactly what keeps this presentation on the demoralization side of that distinction.
