I am no special fan of most books of quotations. Bartlett's Familiar
Quotations, The Yale Book of Quotations, and The New Penguin
Dictionary of Modern Quotations, to name three dependable reference
books, are invaluable, for sure, as repositories of literary and
verbal history. (Countless other books of quotations aren't reliable
at all, and the less said about quotation sites on the Internet the
better.) But even the best contain a good deal of dead weight. They
lean, sometimes necessarily, on canned and overused thought and,
grievously, are skewed to the upbeat. So many of the lines they
contain seem to vie to be stitched onto throw pillows or ladled, like
soup, over the credulous soul. "Almost all poetry is a failure,"
Charles Bukowski contended, "because it sounds like somebody saying,
Look, I have written a poem." The same is true of quotations and
aphorisms. So many have a taxidermied air, as if they were
self-consciously aimed at posterity.
