[Biology and ethics of bioethics: an urgent need of realism]

Tenets and recommendations of bioethics should be based on a profound knowledge of biological processes and at the same time deeply integrated with their human significance. Integration has been usually distorted by those implied in disciplines involved with human nature. Biology of fertilization and embryo development have been often fodder of science fiction, when considering that techniques can achieve any aim without acknowledging natural limits, and often handling data, and accepting without any critical attitude pseudoscientific dogma. In the middle of that pseudo-biology bioethics has suffered the onslaught of the ideology of man believing himself autonomous and claiming he is the only one who dictates the rules of reality of world and man, and leading development and progress with this technological power in his hands. The profoundly different response to this deep question of whether what is properly human and essential to each man emerges as a consequence of his own construction and development or, on the contrary, is inherent to the constitution of each man, has caused the splitting of bioethics into two really irreconcilable bioethics. And that because of their different reasoning and criteria. The Ethics of Bioethics requires a new thinking on this crucial point allowing it to grow as an unprejudiced Science. Serious consequences derive from taking one perspective or another. Adopting one or another perspective confront us with a serious problem. Is human life disposable? Or should it be elegantly preserved?
