There is no disease, bodily or mental, which adoption of vegetable diet and pure water has not infallibly mitigated, wherever the experiment has been fairly tried. Debility is gradually converted into strength, disease into healthfulness: madness, in all its hideous variety, from the ravings of the fettered maniac, to the unaccountable irrationalities of ill-temper, that make a hell of domestic life, into a calm and considerable evenness of temper, that alone might offer a certain pledge of the future moral reformation of society.
Percy Bysshe Shelley
