9Look on my works, ye mighty, and despair 3,080,000 Shelley

1To err is human; to forgive, divine 14,800,000 Alexander Pope
Full Top 50

Some initial thoughts:
  1. What happened to the big guy? Shakespeare's highest entry is a miserable 13 with My mistress’ eyes are nothing like the sun while To be or not to be barely makes the Top 20. 
  2. The Romantics remain crowd pleasers (Wordsworth has two entries, Shelley though perhaps surprisingly Keats lags behind. 
  3. Pompous Christmas Cracker philosophising also good box-office (step forward Mr Tennyson). 
  4. Slightly mystified by Henley's close second. Perhaps he appeals to the modern inclination to personalize ('I am the master of my fate'). Like a mawkish rendition of My Way in a Karaoke bar, the defiance has an undertone of self-pity.  Phillip Larkin provides a bracing antidote to this mindset ('what remains of us is love')
  5. Over-familiarity produces a certain weariness when it comes to the winner. Few would dispute the the profundity of Pope's line. Nonetheless one suspects its victory is due less to literary merit than to its ubiquity in online sermons, religious and secular.
