In this excerpt from "mother" by maxim gorky, which idea is the little russian promoting?
in the small room a vast feeling was born of the universal kinship of the workers of the world, at the same time its masters and its slaves, who had already been freed from the bondage of prejudice and who felt themselves the new masters of life. this feeling blended all into a single soul; it moved the mother, and, although inaccessible to her, it straightened and emboldened her, as it were, with its force, with its joys, with its triumphant, youthful vigor, intoxicating, caressing, full of hope.
"what queer people you are! " said the mother to the little russian one day. "all are your comrades—the armenians and the jews and the austrians. you speak about all as of your friends; you grieve for all, and you rejoice for all! "
"for all, mother dear, for all! the world is ours! the world is for the workers! for us there is no nation, no race. for us there are only comrades and foes. all the workingmen are our comrades; all the rich, all the authorities are our foes. when you see how numerous we workingmen are, how tremendous the power of the spirit in us, then your heart is seized with such joy, such happiness, such a great holiday sings in your bosom! and, mother, the frenchman and the german feel the same way when they look upon life, and the italian also. we are all children of one mother—the great, invincible idea of the brotherhood of the workers of all countries over all the earth. this idea grows, it warms us like the sun; it is a second sun in the heaven of justice, and this heaven resides in the workingman's heart. whoever he be, whatever his name, a socialist is our brother in spirit now and always, and through all the ages forever and ever! "
