Famous quotes containing the words primitive and/or element:

    The most primitive places left with us are the swamps, where the spruce still grows shaggy with usnea.
    Henry David Thoreau (1817–1862)

    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.
