This document discusses the importance of professional ethics, particularly for engineering. It addresses three accounts of what constitutes a profession: sociological, social practice, and Socratic. Engineering can be considered a true profession under the Socratic account, as engineers have extensive training, serve the public good, and are obligated to protect health and safety. However, engineers' status is questionable under other accounts due to lack of complete control over their work and limited autonomy. The document also notes that ethics are crucial for professionalism to maintain public trust and prevent exploitation. Professional ethics provide standards to guide conduct beyond what is legally required.
