Biomedical ethics (Philosophy HL)

The big idea: A doctor stands at a bed. A patient in unbearable pain asks to be allowed to die.

Suddenly the moral theories you've studied aren't abstract anymore — someone's life turns on which one you follow. Biomedical ethics is where big theory meets a real body: birth, death, illness and the power of medicine to change all three.

This is applied ethics in medicine. The hardest cases here are euthanasia, genetic engineering, stem-cell research and abortion — each one forces a theory to show what it really says.

Hold onto this: Applied ethics isn't a new theory. It's the OLD theories — virtue, duty, consequences — put to work on one real case to see what each actually tells you to do.

Take one case — a dying patient begging to be allowed to die — and watch the three main theories pull in different directions.

Checkpoint — euthanasia: In one line: on one dying patient, duty tends to say 'no', consequences tends to say 'yes', and virtue says 'it depends on mercy and the whole situation'. Hold that shape — it works for every case in this field.

The euthanasia pattern repeats across the field — each case just changes what the theories are arguing over.

Go further — higher-level insight: Notice what really divides most biomedical cases: the question of moral status. Is an embryo a full person, a potential person, or a clump of cells? Abortion, stem cells and genetic engineering all turn on that one question. Naming moral status as the hidden hinge is a top-band move.

Checkpoint — the pattern: In one line: most biomedical arguments come down to moral status — who or what counts, and how much — plus the clash of duty, consequences and virtue.
