Final answer:
The Hippocratic Oath, associated with the Greek physician Hippocrates, is the pledge for physicians that remains influential today, focusing on the ethical practice of medicine.
Step-by-step explanation:
A pledge for physicians that remains influential today is the Hippocratic oath. The Greek physician Hippocrates, known as the "father of Western medicine", is often credited with its authorship. Unlike the ancient codes of law such as the Code of Hammurabi, which was an influential legal document from ancient Mesopotamia that outlined rules and penalties, the Hippocratic Oath is specifically focused on medical ethics and practice. It has transcended through centuries to form the foundational ethics of modern medicine, committing physicians to uphold specific ethical standards, including treating patients to the best of one's ability, maintaining patient privacy, and practicing medicine in an ethical manner.
