Abstract

The different versions of bioethics are founded on very specific underlying philosophical and ethical elements. Every philosophical doctrine or current of thought is the source of a particular set of ethics and every set of ethics supports a distinct version of bioethics that is dependent on the wisdom or shortsightedness of both the philosophy and the ethics on which it is based. This paper is an attempt to explain how the relationship between philosophy, ethics and bioethics comes about and to identify the main consequences of the “kinship” determined by that affinity. A hypothetical situation is used to show the various solutions that are possible with five different triads that can be established, at present, as part of that relationship. The bioethical consequences of the “kinship” between philosophy, ethics and bioethics are illustrated on the basis of the foregoing explanation. The limited scope of opinions and their contrast with rational discourse founded on reality leads to several conclusions: solving bioethical problems implies that we start with thinking that is properly supported by a philosophical anthropology that offers the best guarantee of accuracy, rationality, internal consistency and possibility for practice, which subsequently provides the basis for objective ethical thinking that is capable of unmasking any relativism, reductionism or ideologizing. In this way, it will be possible to provide answers to the problems associated with life in general and human life in particular.
