§ 226
It is only such emotional diseases as these, which were first engendered and subsequently kept up by the mind itself, that, while they are yet recent and before they have made very great inroads on the corporeal state, may, by means of psychical remedies, such as a display of confidence, friendly exhortations, sensible advice, and often by a well-disguised deception, be rapidly changed into a healthy state of the mind (and with appropriate diet and regimen, seemingly into a healthy state of the body also.)
