According to the scientist, the current research "in embryo life, which is cloned, hybridised, selected, studied and destroyed, should make us think" of the image of man "we are promoting". "We are turning human embryo life into a plan which is in the hands of the adults’ wishes and fears, as well as those of the interests of research", he states, and perhaps "we still do not realise how serious these choices are". "Accepting the idea that there is such thing as a primacy of scientific research, even if for therapeutic purposes insists Pessina , means introducing again a discrimination between men, who would be rated according to the stages of their development or their usefulness". But even objecting "politically to such plans in the name of the fact they would not deliver the expected and promised therapeutic effects is equally serious and short-sighted as allowing them he explains , because it inherently means that, if it delivered results, then this kind of research would be warranted", while "the first task of politics is to protect the principle of equality, which is the foundation of democracy". "We need some extra reflection and courage concludes Pessina -: freedom can also be asserted through a justified rejection of the manipulation of human life".
