The notion of consent which rose to the forefront in biomedical ethics as an attempt to safeguard patients' autonomy, is relatively new. The notion itself requires qualification, for it precludes neither duress nor ignorance. More seriously, I argue here that consent is redundant except in situations where paternalism prevails. Paradoxically, these are the very situations where it may be difficult to uphold or to verify voluntary consent. I suggest that a request-based relationship has the potential to overcome these difficulties. It (...) enhances patients' participation in decision making, requires that the patients remain in command and avoids their subordination. Request is also more conducive to treatments that are representative of patients' own values and perceptions. In practice, what one wants and what one agrees to, often concur. But these are not conceptually identical issues, and they carry important differences of emphasis. (shrink)
