@Setanta,
Quote:we can't hold back the tides of change.
I once heard a short piece of drama on BBC Radio called "On Dover Beach" by Tom Stoppard in which the actor Alan Howard voiced two parts: Matthew Arnold and a notional ruthless critic, doing a demolition job on Arnold's most famous poem (one of my favourites). The critic points out that the poem's central metaphor was a turkey: tides go in as well as out. Not only that, whatever it was that Sophocles heard long ago on the Aegean, it wasn't the tide, since that sea is not tidal. Arnold groans "That's not criticism; it's oceanography!"
