People who have cut their teeth on philosophical problems of rationality, knowledge, perception, free will and other minds are well placed to think better about problems of evidence, decision making, responsibility and ethics that life throws up.

It is the thought that the least efficient way of of finding either happiness or pleasure is to pursue them. Put in terms of happiness, we can see it like this: To be happy you must quite literally "lose yourself". You must lose yourself in some pursuit; you need to forget your own happiness and find other goals and projects, other objects of concern that might include the welfare of some other people, or the cure of the disease, or simply in the variety of everyday activities with their little successes and setbacks.

One peculiarity of our present [ethical] climate is that we care much more about our rights than about our 'good'. For previous thinkers about ethics, such as those who wrote the Upanishads, or Confucius, or Plato, or the founders of the Christian tradition, the central concern was the state of one's soul, meaning some personal state of justice or harmony. Such a state might include resignation or renunciation, or detachment, or obedience, or knowledge, especially self-knowledge. For Plato there could be no just political order except one populated by just citizens.... Today we tend not to believe that; we tend to think that modern constitutional democracies are fine regardless of the private vices of those within them. We are much more nervous talking about our good: it seems moralistic, or undemocratic, or elitist. Similarly, we are nervous talking about duty. The Victorian ideal of a life devoted to duty, or a calling, is substantially lost to us. So a greater proportion of our moral energy goes to protecting claims against each other, and that includes protecting the state of our soul as purely private, purely our own business.

There are normal times when it is wholly admirable to be steadfast, resolute, unconflicted, and therefore when integrity is unmistakenly a virtue. The person of integrity knows what to do, and does it. But as we have been exploring, there are also times when certainty and single-mindedness indicate something less admirable: a deafness to voices that should be heard or a blindness to aspects of a situation that need to be considered.
