It is possible to ask itself which is the moment of the gestation in which it can be said that new born it begins to live, to perceive sensations and to react consequently, stopping being a totally passive organism, although it continues receiving from the mother all whatever needs (foods, oxygen and heat) through umbilical cord.
Could be spoken of no temporary between such event and the conception?
And, in any case what life one is?
Of a vegetative life or also of uiia psychic life?
They are these some of the questions for which still one is very far from finding definitive answers. 
However, in the last years science has extended considerably its knowledge around such questions.
Formerly employee considered itself that, during the intrauterine life, the fetus was a fragile organism, totally, that was developed calmly, equipping itself little by little of all the physical structures and the energy necessary to face a day the outer world, until arriving the moment from the birth, “moment zero”, the newborn one, to discover that she had Vista and voice, began to put in operation a psychic system already formed, but until then made unusable, impermeable as much to the stimuli coming from the atmosphere represented by the amniotic liquid and the placenta like a those of the world in which vivid the mother.
This was what it thought before.
Nowadays one knows that it is not thus. The medicine has demonstrated that the manifestation of the conscience and therefore of the free expression of the sensorial possibilities is not a successive fact to the traumatic separation that supposes the birth, but that has to be located long before, already turned the fourth month of gestation, when eyes, nose and mouth are complete, the cardiac beat is to regulate and the sexual organs are developed.
As of that moment, for example, the fetus, thanks to tactile sensitivity, react to the pressures and the vibrations; thanks to the ear perceive and recognize the beat of the heart of the mother and the waves coming from the outside.
It means that the future breasts have not spoken until now in vain to the creature which took in their inside, that this affectionate verbal monologue; prefiguration of I engage in a dialog but satisfactory, an impulse devoid of effects cannot already be considered sentimental.
Evidently, the fetus cannot understand the sense of the words, but it has verified that is in conditions for perceiving the difference between a tender and calm tone and another anxious one and worried; either the alternancy in the rate of the voice, hurried or slow, to him does not happen unnoticed.
As opposed to such stimuli, the fetus responds: it changes of position, it modifies the duration of the periods of watch and dream, makes alive movements or remains immovable.
Of course there are many different views of the issues surrounding early human life. The moral controversies about early human life are further complicated by the fact that there are several different methodologies deployed in framing these views. Ford is mindful of these different audiences and conversation partners as he develops the book. He pays careful attention to other views.
The particular moral position that has been, and remains, important to many people in bioethics and the practice of medicine. The book is an excellent examination of this tradition of thought and applies that tradition well to many difficult and contentious issues. It is also to be recommended as an attempt to put the natural law tradition in dialogue with other key lines of thought in contemporary bioethics. It is well written, insightful, and touches on some of the most controversial issues in the field. Even if one disagrees with the arguments and the foundational position, it is a book that ought to be part of the ongoing debates around these issues.
