Famous quotes containing the words coherent, scatter and/or echoes:

    “We have good reason to believe that memories of early childhood do not persist in consciousness because of the absence or fragmentary character of language covering this period. Words serve as fixatives for mental images. . . . Even at the end of the second year of life when word tags exist for a number of objects in the child’s life, these words are discrete and do not yet bind together the parts of an experience or organize them in a way that can produce a coherent memory.”
    —Selma H. Fraiberg (20th century)

    “There is no beautifier of complexion, or form, or behavior, like the wish to scatter joy and not pain around us.”
    —Ralph Waldo Emerson (1803–1882)

    “Thru all the tumult and the strife,
    I hear that music ringing.
    It sounds and echoes in my soul;
    How can I keep from singing?”
    —Quaker. (Worship Comes Alive)
