True philosophy is a living wisdom, for which there is no death. - Ernst, Baron von Feuchtersleben

Those views of life which deify pleasure are less likely to yield it.

A treatise on mental dietetics would be imperfect without some special notice of that most irrational and melancholy of all human torments, hypochondriasis. Reason, morality, wit, and even religion, have endeavoured by every possible means to exorcise this demon. By pamphlets and by books—in tragedy and in comedy — from the pulpit and on the stage, it has been denounced and ridiculed.

"He who wounds me" exclaims an animated writer, “ injures my body only: but he who wearies me assassinates my soul.” And he who wearies himself needs to be placed under a system of mental dietetics.
