Famous quotes containing the words primary and/or channel:

    The traditional American husband and father had the responsibilities—and the privileges—of playing the role of primary provider. Sharing that role is not easy. To yield exclusive access to the role is to surrender some of the potential for fulfilling the hero fantasy—a fantasy that appeals to us all. The loss is far from trivial.
    Faye J. Crosby (20th century)

    Eddie did not die. He is no longer on Channel 4, and our sets are tuned to Channel 4; he’s on Channel 7, but he’s still broadcasting. Physical incarnation is highly overrated; it is one corner of universal possibility.
    Marianne Williamson (b. 1953)
