Famous quotes containing the words james and/or cannon:
“Happy you poets who can be present and so present by a simple flicker of your genius, and not, like the clumsier race, have to lay a train and pile up faggots that may not after prove in the least combustible!”
—Henry James (1843–1916)
“We may say that feelings have two kinds of intensity. One is the intensity of the feeling itself, by which loud sounds are distinguished from faint ones, luminous colors from dark ones, highly chromatic colors from almost neutral tints, etc. The other is the intensity of consciousness that lays hold of the feeling, which makes the ticking of a watch actually heard infinitely more vivid than a cannon shot remembered to have been heard a few minutes ago.”
—Charles Sanders Peirce (1839–1914)
