Abstract
‘Of all the difficulties which impede the progress of thought and the formation of well- grounded opinions on life and social arrangements’, wrote John Stuart Mill around 150 years ago, ‘the greatest is now the unspeakable ignorance and inattention of mankind in respect of the influences which form character’. Aristotle is never far in the background of Mill’s moral and political philosophy, a presence weightier than Jeremy Bentham’s in the foreground. That this is often overlooked is not only because thinkers tend to be pigeonholed into a single school and Mill eschews the language of virtue. It is also because moral and political philosophers did not heed Mill’s words and continued for over a century to pay very little attention to the nature and development of character.
