Famous quotes containing the words primary and/or channel:

    “The primary function of myth is to validate an existing social order. Myth enshrines conservative social values, raising tradition on a pedestal. It expresses and confirms, rather than explains or questions, the sources of cultural attitudes and values.... Because myth anchors the present in the past it is a sociological charter for a future society which is an exact replica of the present one.”
    —Ann Oakley (b. 1944)

    “Wherever there is a channel for water, there is a road for the canoe.”
    —Henry David Thoreau (1817–1862)
