“People living in the vanity of their own mind not only destroy themselves, but far too often, they bring destruction to others around them.”

Part I, p. 2.
The Autobiography (1818)
Context: Indeed I scarce ever heard or saw the introductory Words, Without Vanity I may say, etc. but some vain thing immediately follow'd. Most People dislike Vanity in others whatever Share they have of it themselves, but I give it fair Quarter wherever I meet with it, being persuaded that it is often productive of Good to the Possessor and to others that are within his Sphere of Action: And therefore in many Cases it would not be quite absurd if a Man were to thank God for his Vanity among the other Comforts of Life.

Non hanno gli huomini maggior nimico che la troppa prosperità, perchè gli fa impotenti di se medesimi, licentiosi et arditi al male, e cupidi di turbare il ben proprio con cose nuove.

On the Mindless Menace of Violence (1968)
Context: Too often we honor swagger and bluster and wielders of force; too often we excuse those who are willing to build their own lives on the shattered dreams of others. Some Americans who preach non-violence abroad fail to practice it here at home. Some who accuse others of inciting riots have by their own conduct invited them. Some look for scapegoats, others look for conspiracies, but this much is clear: violence breeds violence, repression brings retaliation, and only a cleansing of our whole society can remove this sickness from our soul.
