Some of Plato's Views on the Art of Medicine

In Plato's Laws (Book 4, 720a-720e), he describes the differences between two types of doctors: the free-born doctor and the slave doctor. He says that both types of doctors acquire their art under the direction of their teachers or masters, by observation and practice, rather than by the study of nature. However, a free-born doctor is mostly engaged in visiting and treating the ailments of free people, and he does so by listening to their complaints, not prescribing any treatment without their consent. A slave doctor, on the other hand, is engaged in treating slaves and doesn't listen to any account of their ailments. He simply prescribes treatment based on his own experience and on what he thinks is best. He does so with the confidence and assurance of a tyrant or autocrat, then rushing off to see some other sick slaves so that his master won't be bothered by having to attend to them.

      In the same way, the Athenian lawgiver has a choice of two kinds of methods, persuasion or compulsion. The lawgiver has it in his power to use both methods, but he may mistakenly think that his legislation can be enacted by force alone. To ensure that those who are governed by his laws will actually obey them, the lawgiver must offer those whom he governs some kind of persuasion, just as a free-born doctor must offer his free-born patient a persuasive rather than despotic prescription.

      Plato's medical analogy has several implications for our current views of biomedical ethics. It indicates the need for doctors to listen to their patients, and to fully inform them about their conditions, as well as about possible diagnostic modalities, therapeutic options, and possible side-effects of treatment. It also indicates the need for doctors to obtain informed consent from their patients for treatment, and to fully engage and coordinate with their patients in order to ensure their compliance with treatment. It also indicates that the efficacy of treatment may depend on clear and effective communication between patients and providers, as well as on coordination of care, timeliness and appropriateness of care, compassionate care, respect for patient privacy and autonomy, respect for patient dignity, collaboration between patients and providers, and other components of the patient-provider relationship.

      In Plato's Republic, Socrates says that the physician studies only the patient's interest, and not his own (I. 342). Socrates also says that Asclepius treated patients by means of drugs or the knife in order to enable them to go on living as usual, but would not try to prolong the lives of those with advanced disease whose existence was miserable (III. 407). Socrates agrees with Glaucon that the best physicians may be those with the widest experience in treating healthy and sick patients, but he adds that physicians who have themselves suffered from various illnesses may be even more capable of treating those illnesses (III. 408).
