A profession is not a business.
It is distinguished by the requirements of extensive formal training and learning,
admission to practice by qualifying licensure,
a code of ethics imposing standards qualitatively and
extensively beyond those that prevail or are tolerated in the marketplace,
a system for discipline of its members for violation of the code of ethics,
a duty to subordinate financial reward to social responsibility,
and, notably,
an obligation on its own members, even in nonprofessional matters,
to conduct themselves as members of a learned, disciplined,
and honorable occupation.
