The line ‘Integrity is doing the right thing when, even when no one is looking.’ is commonly misattributed to the author of The Chronicles of Narnia C S Lewis. Although Lewis covered a similar theme in his work Mere Christianity the quote is actually taken from ‘Shattering the Glass Slipper’ the work of contemporary motivational speaker Charles Marshall. Whilst many of us will be familiar with work of C S Lewis far fewer, myself included will have read Marshall. Of course, the truth of an aphorism is not dependent on its authorship but the idea itself.
