Famous quotes containing the words writing, paper and/or standards:
“Faithfulness to the past can be a kind of death above ground. Writing of the past is a resurrection; the past then lives in your words and you are free.”
—Jessamyn West (1902–1984)
“To summarize the contentions of this paper then. Firstly, the phrase ‘the meaning of a word’ is a spurious phrase. Secondly and consequently, a re-examination is needed of phrases like the two which I discuss, ‘being a part of the meaning of’ and ‘having the same meaning.’ On these matters, dogmatists require prodding: although history indeed suggests that it may sometimes be better to let sleeping dogmatists lie.”
—J.L. (John Langshaw)
“Barbarism is the absence of standards to which appeal can be made.”
—José Ortega Y Gasset (1883–1955)
