Karl Marx
“The production of too many useful things results in too many useless people.”
“All that is solid melts into air, all that is holy is profaned.”
“The ruling ideas of each age are the ideas of its ruling class.”
“From each according to his ability, to each according to his needs.”
“History repeats itself, first as tragedy, second as farce.”
“Workers of the world, unite! You have nothing to lose but your chains.”
“Religion is the opium of the people.”
“The philosophers have only interpreted the world, in various ways; the point, however, is to change it.”
