3. A toolbox of reasoning
‘A toolbox of reasoning’ discusses a further four tools of ethical reasoning: distinguishing facts from values; reasoning from principles; thought experiments; and spotting and avoiding fallacies in reasoning. Five fallacies are discussed: the no-true Scotsman move; the ten-leaky-buckets tactic; the argument from nature; the argument from playing God; and the slippery slope argument. It also explains how the analysis of medical ethics is organized around four principles—respect for patient autonomy, beneficence, non-maleficence, and justice—and their scope of application. Ethical reasoning cannot be reduced to algorithms. Situations are complex and doing the right thing will often require flexibility. Humane medicine, in addition to rationality, requires wisdom, imagination, and creativity.
