title: [Scientific ethics and frozen embryos].
abstract: Scientific Ethics is the theory and praxis of decisions. Philosophical Ethics is presented as the theory and praxis of the good. As the good differs among cultures, Philosophical Ethics is dependent on the endo-cultural good conception. The decision (included that one of adhesion or not to a world vision) depends on neuro-psychic specific factors: i) cognitive factors that include mostly the knowledge of the alternatives and their consequences and the ideological or religious conception of good in relation to the alternatives; ii) affective factors that make alternatives pleasant, unpleasant or neutral, attractive, repulsive or neutral; iii) emotional factors that associate to alternatives anger, peace or neutrality, sadness, happiness or neutrality; iv) value factors that assign importance, triviality or neutrality to alternatives, or assign them significance, irrelevancy or neutrality. There are unspecific factors such as the psychic energy, desire or others. Mixed factors such as attitude, motivation, intention and others. Scientific Ethics deals with the mind as a materio-energetic process which is different from the soul, eggs and embryos of any species are full individuals of that species, because, they have initiated a copy of their genome that specify, give autonomy and define them as individuals. For Scientific Ethics to leave frozen embryos like that for ever, to defrost and get rid of them or to use their cells for science are synonymous of killing them. To defrost them to use their cells as stem cells for somatic cell therapy or to implant them into uteri to continue their development is to maintain alive their cells, but only the implantation allows their maintenance as individuals, thus, being the only compatible with the Christian ethics. The compatibility of these alternatives with other ethics is discussed.
