Joseph Stalin said this quote

...[I]ron discipline does not preclude but presupposes criticism and contest of opinion within the Party. Least of all does it mean that discipline must be 'blind'. On the contrary, iron discipline does not preclude but presupposes conscious and voluntary submission, for only conscious discipline can be truly iron discipline.

~ Joseph Stalin

Death is the solution to all problems. No man-no problem.

~ Joseph Stalin

If there are no isolated phenomena in the world, if all phenomena are interconnected and interdependent, then it is clear that every social system and every social movement in history must be evaluated not from the standpoint of eternal justice or some other preconceived idea, as is not infrequently done by historians, but from the standpoint of the conditions which gave rise to that system or that social movement and with which they are connected.

~ Joseph Stalin

It is difficult for me to imagine what personal liberty is enjoyed by an unemployed person, who goes about hungry, and cannot find employment.Real liberty can exist only where exploitation has been abolished, where there is no oppression of some by others, where there is no unemployment and poverty, where a man is not haunted by the fear of being tomorrow deprived of work, of home and of bread. Only in such a society is real, and not paper, personal and every other liberty possible.
