For Franklin, what is the purpose of writing down the list of virtues? because he wants to share the virtues so that his descendants will know him in order to practice them one by one in order to teach others to practice them

In order to practice them one by one

Benjamin Franklin decided to write down a list of thirteen virtues in order to practice them. As he stated himself "I propos'd to myself, for the sake of clearness, to use rather more names, with fewer ideas annex'd to each, than a few names with more ideas; and I included under thirteen names of virtues all that at that time occurr'd to me as necessary or desirable, and annexed to each a short precept, which fully express'd the extent I gave to its meaning".
