One of the benefits I have obtained from reading Nicholas Phillipson’s excellent book, ‘Adam Smith, an Enlightened Life’ is a better understanding of what Smith was trying to achieve in writing ‘The Theory of Moral Sentiments’ (TMS). He apparently saw the book as a contribution to a ‘science of man’ based on the observation of human nature and human history. As such, it provided a theory of sociability as well as a theory of ethics.
Smith acknowledged that everyone wants to better their condition. At one point he even seems to imply that everyone places higher priority on improving their relative position in society than on achieving an easier and more pleasurable life (TMS: 50). (My grandmother, whose life became easier and more pleasurable in the 1950s after she obtained her first refrigerator and washing machine, might have thought that comment to suggest that Smith was not sufficiently aware that he lived a privileged life. But I digress!)
Smith also makes the point that individuals should be responsible for looking after their own interests: ‘Every man is, no doubt, by nature, first and principally recommended to his own care; and as he is fitter to take care of himself than of any other person, it is fit and right that it should be so’ (TMS: 82). (I think Smith makes a stronger case for individual freedom here than who make the dubious claim that each individual is always the best judge of his or her own interests. But I digress again!)
Impartial spectators condemn violations of fair play among individuals competing to better themselves:
Smith’s ethics is based on the simple proposition that when individuals reflect upon their own past actions from the viewpoint of an impartial spectator they feel remorse when they have acted unjustly. His response to critics who suggested that he was reducing the principles of ethics to popular culture was that while children might seek to be universally agreeable, mature people who have important interests to manage find that they cannot please everyone. While some people might be content to follow popular culture, those who are morally responsible and fitted for public life have to establish their own impartial spectators as a judges in their own minds (Phillipson, p164-165).
However, I don’t think it is particularly useful to try to think about development of identity and character outside the context of social interactions that reward particular behaviours and penalize others. It seems to me to be a fact of life that a person who identifies strongly as a member of a small community and has limited social interactions outside that community is less likely to feel conscience-stricken if he or she acts unjustly towards a stranger than towards another community member. The ethics of respect for the rights of strangers is no doubt encouraged to some extent by abstract ideals that would be endorsed by impartial spectators, but is likely to be more strongly encouraged by mutually beneficial commerce which offers ongoing rewards for ongoing cooperation between strangers.
