The word ‘autonomy’ is derived from the Greek ‘self’ (αὐτός; autos), and ‘law’ (νόμος; nomos), and has the ordinary meaning of the right or condition of self-government, in the sense of the ability to act free from external control or influence.
This freedom, applied to one’s own body, and even one’s own life, is by necessity limited. Three examples, from minor to major, illustrate the kind of limitations we have on our autonomy, for our own good as well as that of others:
If ‘autonomy’ were absolute on a bodily level, it would mean that the cases of limitation above would not apply, and the same logic applies in consideration over the autonomy of individuals who wish to decide the timing and nature of the end of their own life. On a social level, if personal autonomy in this area were absolute, then it would be considered a violation of individual sovereignty to rescue (prevent) someone attempting suicide from the ledge of a tall building, from a train platform, or from a waterway. Instead, we consider such actions heroic, not coercive.
Clearly, individual autonomy is not (and cannot rationally be) seen as an absolute principle, whether in medicine or in any other sphere of social existence, but one which is heavily contingent on what is good for the health and broader personal welfare of the individual autonomous actor, let alone that of others.
Another reason why ‘autonomy’ is inappropriately invoked in this context is that whilst autonomous choice involves one actor, assisted suicide (as with any medicalised interaction) involves two: the patient and the doctor. In medicine, just as the claim that ‘autonomy’ even means sovereign choice over one’s body is simply untrue, the idea that it involves an ability to access any medical benefit at all simply is not a credible proposition, as the example above of access to antibiotics illustrates.
This is an important point to consider in light of the dangers of assisted suicide to the most vulnerable of patients.
