Promises Are Not To Be Kept, If

The Wise Are Instructed By Reason, Average Minds By Experience, The Stupid By Necessity And The Brute By Instinct.

We Must Not Say That Every Mistake Is A Foolish One.

O Philosophy, Life's Guide! O Searcher-out Of Virtue And Expeller Of Vices! What Could We And Every Age Of Men Have Been Without Thee? Thou Hast Produced Cities; Thou Hast Called Men Scattered About Into The Social Enjoyment Of Life. [lat., O Vitae Philosophia Dux! O Virtutis Indagatrix, Expultrixque Vitiorum! Quid Non Modo Nos, Sed Omnino Vita Hominum Sine Et Esse Potuisset? Tu Urbes Peperisti; Tu Dissipatos Homines In Societatum Vitae Convocasti.]

There Exists A Law, Not Written Down Anywhere But Inborn In Our Hearts; A Law Which Comes To Us Not By Training Or Custom Or Reading But By Derivation And Absorption And Adoption From Nature Itself; A Law Which Has Come To Us Not From Theory But From Practice, Not By Instruction But By Natural Intuition. I Refer To The Law Which Lays It Down That, If Our Lives Are Endangered By Plots Or Violence Or Armed Robbers Or Enemies, Any And Every Method Of Protecting Ourselves Is Morally Right.

The Most Desirable Thing In Life After Health And Modest Means Is Leisure With Dignity.
