DISEASE
—is not only a state of the body directly opposite to the standard of health, but may be defined of two kinds; as those with which we are afflicted by the influence of a superior Power, whose wisdom we are not permitted to explore; and by others that, in acts of neglect and indiscretion, we bring upon ourselves. Diseases are differently conceived: some writers describe them by their cause, some by their effect: leaving the investigation in a kind of medical mystery, bearing no ill affinity to theological ambiguity. In fact, the word is only introduced here to remind every reader, that, in respect to both MAN and HORSE, prevention is preferable to CURE.
