“If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.”
― Sun Tzu, The Art of War

“The last capitalist we hang shall be the one who sold us the rope.”
― Karl Marx

“In a higher phase of communist society, after the enslaving subordination of the individual to the division of labor, and therewith also the antithesis between mental and physical labor, has vanished; after labor has become not only a means of life but life's prime want; after the productive forces have also increased with the all-around development of the individual, and all the springs of co-operative wealth flow more abundantly—only then can the narrow horizon of bourgeois right be crossed in its entirety and society inscribe on its banners: From each according to his ability, to each according to his needs!”
― Karl Marx, Critique of the Gotha Program

“...[G]reat progress was evident in the last Congress of the American 'Labour Union' in that among other things, it treated working women with complete equality. While in this respect the English, and still more the gallant French, are burdened with a spirit of narrow-mindedness. Anybody who knows anything of history knows that great social changes are impossible without the feminine ferment. Social progress can be measured exactly by the social position of the fair sex (the ugly ones included).”
― Karl Marx , Selected Letters: The Personal Correspondence 1844-1877
