Famous quotes containing the words primitive and/or element:

    The glory of the farmer is that, in the division of labors, it is his part to create. All trade rests at last on his primitive activity.
    Ralph Waldo Emerson (1803–1882)

    One can describe a landscape in many different words and sentences, but one would not normally cut up a picture of a landscape and rearrange it in different patterns in order to describe it in different ways. Because a photograph is not composed of discrete units strung out in a linear row of meaningful pieces, we do not understand it by looking at one element after another in a set sequence. The photograph is understood in one act of seeing; it is perceived in a gestalt.
