Health is traditionally held to be the absence of disease. But that is a negative definition. A plant that has a stunted growth may not be suffering from a disease, but that doesn’t mean it is healthy. Under the traditional definition, a person who is unhappy, anxious, bored, who feels that life has no meaning, who feels extremely lonely, who is unsure of his powers of judgment and understanding, just to mention a few of the symptoms, can nevertheless be perfectly healthy. But such a man is by no means fulfilled.
