R. G. Collingwood, The Principles of Art (Oxford: Clarendon Press, 1938), p. 7:
The obsolete meanings which every word with a history is bound to possess are the meanings it once had, and retains by force of habit. They form a trail behind the word like that of a shooting star, and divide themselves according to their distance from it into more and less obsolete. The very obsolete are not a danger to the present use of the word; they are dead and buried, and only the antiquary wishes to disinter them. But the less obsolete are a very grave danger. They cling to our minds like drowning men, and so jostle the present meaning that we can only distinguish it from them by the most careful analysis.
