Final answer:
The ethical duty to "do no harm" aligns with the principle of nonmaleficence, which imposes an obligation to minimize potential harm to others, especially in medical and research settings.
Step-by-step explanation:
The phrase "Above all, do no harm" is synonymous with the ethical principle of nonmaleficence, which is particularly important in medical and research settings. This principle dictates that actions should not cause harm to others, and in the context of research, it requires that all trials are designed to reduce harm to participants to the greatest extent possible. The duty to minimize harm while maximizing benefits can be linked to the principle of non-maleficence, which is fundamental in the field of medical ethics and research. This differs from the principle of beneficence, which focuses on acting in ways that benefit others and contribute to their well-being.
