Man is a universe within himself.

The problem is with man himself and man's soul. We haven't learned how to be just and honest and kind and true and loving.

The highest wisdom has but one science - the science of the whole - the science explaining the whole creation and man's place in it.

The animal is one with its life activity. It does not distinguish the activity from itself. It is its activity. But man makes his life activity itself an object of his will and consciousness. He has a conscious life activity. It is not a determination with which he is completely identified.

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.

If we do not act, we shall surely be dragged down the long, dark, and shameful corridors of time reserved for those who possess power without compassion, might without morality, and strength without sight.
