A colleague recently sent me a book on “character development” to achieve a life well-lived. The points made seemed to channel the old Protestant Ethic. I then took out an old book (printed in 1668) which I had purchased long ago in London. It is called “A Gentleman’s Calling” and was first published in 1660.
On looking through it, I ran across this passage which argues, in Protestant terms, of the happy coincidence between duty and advantage. This had also a truism to Cicero in his book, De Officiis. It is a moral stance predicting the feasibility of a moral capitalism.
