I would like experts to provide me with the philosophers of the 1500-1620 period who discussed "ethics" in all or parts of their career. Erasmus, Montaigne, Castiglione, Bruno, Sidney and their likes come to mind immediately. I would appreciate anyone who can introduce me to other lesser anthologized and known thinkers and their books or essays on the subject. Any source, even famous ones, will be greatly appropriated.
