Famous quotes containing the words solar and/or activity:

    “The solar system has no anxiety about its reputation, and the credit of truth and honesty is as safe; nor have I any fear that a skeptical bias can be given by leaning hard on the sides of fate, of practical power, or of trade, which the doctrine of Faith cannot down-weigh.”
    —Ralph Waldo Emerson (1803–1882)

    “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)
