Famous quotes containing the words water, activity and/or content:
“Compare society to a boat. Her progress through the water will not depend upon the exertion of her crew, but upon the exertion devoted to propelling her. This will be lessened by any expenditure of force in fighting among themselves, or in pulling in different directions.”
—Henry George (1839–1897)
“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.”
—Karl Marx (1818–1883)
“Our frigate takes fire,
The other asks if we demand quarter?
If our colors are struck and the fighting done?
Now I laugh content for I hear the voice of my little captain,
We have not struck, he composedly cries, we have just begun our part of the fighting.”
—Walt Whitman (1819–1892)
