“Shared danger is the strongest of bonds; it will keep men united in spite of mutual dislike and suspicion.”

Context: None are so deeply interested to resist the present rebellion as the working people. Let them beware of prejudice, working division and hostility among themselves. The most notable feature of a disturbance in your city last summer, was the hanging of some working people by other working people. It should never be so. The strongest bond of human sympathy, outside of the family relation, should be one uniting all working people, of all nations, and tongues, and kindreds. Nor should this lead to a war upon property, or the owners of property. Property is the fruit of labor — property is desirable — is a positive good in the world. That some should be rich, shows that others may become rich, and hence is just encouragement to industry and enterprise. Let not him who is houseless pull down the house of another; but let him labor diligently and build one for himself, thus by example assuring that his own shall be safe from violence when built.

On the Irrepressible Conflict (1858)
Context: As a general truth, communities prosper and flourish, or droop and decline, in just the degree that they practise or neglect to practise the primary duties of justice and humanity. The free-labor system conforms to the divine law of equality, which is written in the hearts and consciences of man, and therefore is always and everywhere beneficent.
The slave system is one of constant danger, distrust, suspicion, and watchfulness. It debases those whose toil alone can produce wealth and resources for defence, to the lowest degree of which human nature is capable, to guard against mutiny and insurrection, and thus wastes energies which otherwise might be employed in national development and aggrandizement. The free-labor system educates all alike, and by opening all the fields of industrial employment and all the departments of authority, to the unchecked and equal rivalry of all classes of men, at once secures universal contentment, and brings into the highest possible activity all the physical, moral, and social energies of the whole state.

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.
