Abstract

The article starts from the observation that lying or rather the absence of truth- ful communication is still a common practice within modern medicine, and that medical ethics lacks moral arguments sufficient to serve as an efficient therapy of this illness. With regard to the problem of paternalistic justifications of emergency lies, I defend the classical definition and position regarding lying of Augustine and Kant, along with an uncommon interpretation of it. Thus, their aim is not to inhumanely condemn every single merciful lie but to make clear that every attempt to justify lies based on beneficence or »Menschenliebe« (Kant) has to be rejected, because it gives rise to a general praxis of untruthful behaviour. In order avoid this consequence, one must be aware of what makes lying as such morally wrong. This has to be clarified by referring to the ethical-existential Sinnhorizont of truth and truthfulness within the entire context of personal human existence.
