Letter 78 — On the Healing Power of the Mind (§5)

“These, then, are the remedies to which you should have recourse. The physician will prescribe your walks and your exercise; he will warn you not to become addicted to idleness, as is the tendency of the inactive invalid; he will order you to read in a louder voice and to exercise your lungs the passages and cavity of which are affected; or to sail and shake up your bowels by a little mild motion; he will recommend the proper food, and the suitable time for aiding your strength with wine or refraining from it in order to keep your cough from being irritated and hacking.”
