Nature is man's inorganic body -- that is to say, nature insofar as it is not the human body. Man lives from nature -- i.e., nature is his body -- and he must maintain a continuing dialogue with it is he is not to die. To say that man's physical and mental life is linked to nature simply means that nature is linked to itself, for man is a part of nature.
Karl MarxThere is one great fact, characteristic of this our nineteenth century, a fact which no party dares deny.

Karl MarxIn communist society, where nobody has one exclusive sphere of activity but each can become accomplished in any branch he wishes, society regulates the general production and thus makes it possible for me to do one thing today and another tomorrow, to hunt in the morning, fish in the afternoon, rear cattle in the evening, criticize after dinner, just as I have a mind, without ever becoming hunter, fisherman, shepherd or critic.
