First, agreeing partly with Koehn’s view, Camenisch says that professionals promise to serve the public good, whether their promises are made explicitly as oaths or implicitly by voluntarily taking on professional roles. Second, agreeing partly with Davis’s view, professionalism requires “paying one’s dues” by meeting shared responsibilities rather than unfairly exploiting other professionals.18Close Third, adding his own emphasis, professionals owe a duty of gratitude to abide by the responsibilities society requires, because they voluntarily accept society’s gifts. These gifts include the financial support that underwrites their education through scholarships and general funding. They include the establishment of institutions that support their work. And they include special privileges such as allowing monopolies over professional services, which bring high salaries, job security, and social prestige.
