Karl Marx quotes - page 5
[The career a young man should choose should be] one that is most consonant with our dignity, one that is based on ideas of whose truth we are wholly convinced, one that offers us largest scope in working for humanity and approaching that general goal towards which each profession offers only one of the means: the goal of perfection ... If he works only for himself he can become a famous scholar, a great sage, an excellent imaginative writer [Dichter], but never a perfected, a truly great man.
Karl Marx
The fact that labour is external to the worker, i.e., it does not belong to his intrinsic nature; that in his work, therefore he does not affirm himself but denies himself, does not feel content but unhappy, does not develop freely his physical and mental energy but mortifies his body and his mind. The worker therefore only feels himself outside his work, and in his work feels outside himself.
Karl Marx
