I am reading Kwame Anthony Appiah's Ethics of Identity. Appiah is a philosopher here exploring the relationship between individuality and ethics. Particularly, he has evoked the topic of "ethical flourishing," defining that as, in my paraphrase, living the best life one can lead.
His whole first chapter is on John Stuart Mill. There's a quote of of Mill's which I must duplicate here. This was written in a letter to his friend, David Barclay:
"'There is only one plain rule of life eternally binding...try thyself unweariedly till thou findest the highest thing thou art capable of doing, faculties and outward circumstances being both duly considered, and then DO IT.'"
How can I expound on this without taking away from it? I believe it stands on its own...
