Famous quotes containing the words selective and/or calling:
“The selective memory isn’t selective enough.”
—Blake Morrison (b. 1950)
“Instead of calling on some scholar, I paid many a visit to particular trees, of kinds which are rare in this neighborhood, standing far away in the middle of some pasture, or in the depths of a wood or swamp, or on a hilltop.... These were the shrines I visited both summer and winter.”
—Henry David Thoreau (1817–1862)
