Letter 95 — On the Usefulness of Basic Principles (§59)

“for sometimes you are deceived and believe that certain things are worth more than their real value; in fact, so badly are you deceived that you will find you should value at a mere pennyworth those things which we men regard as worth most of all—for example, riches, influence, and power. You will never understand this unless you have investigated the actual standard by which such conditions are relatively rated. As leaves cannot flourish by their own efforts, but need a branch to which they may cling and from which they may draw sap, so your precepts, when taken alone, wither away; they must be grafted upon a school of philosophy.”
