“Words are magical in the way they affect the minds of those who use them. ‘A mere matter of words,’ we say contemptuously, forgetting that words have power to mold men’s thinking . . . to direct their willing and acting.” (Aldous Huxley, Words and Their Meanings, 1940).

Take a minute to discover what some of these words commonly used in bioethics really mean.

Autonomy: the right of competent adults to make informed decisions about their own medical care.

Beneficence: the ethical obligation to do good and avoid causing harm.

Benefit: a desirable outcome or state of affairs, and it could be life-sustaining or making the patient more comfortable.

Euthanasia: the deliberate killing of a human being for the stated reason of compassion. Sometimes divided into two subcategories: passive and active.
