In Western democratic society, the specificity of the bioethical debate over the life-sciences involves bringing together many different study factors. The dilemmas raised by the new scientific discoveries highlight how contemporary common sense is plagued by a profound feeling of anguish over possible future anthropological developments. One of the central problems is the social construction of consent as a psychological strategy seeking to orient public opinion toward accepting new applications of science and technology. On the one hand, the general features (...) in the epistemological analysis of the mind-brain identity are called into question; and on the other, together with all those research directions concerned with the "meaning of life," we enter the dimension of the complex issue inherent in the possibility of establishing if there exists something transcending thought and what it may be. In both cases a problem is raised on which the meaning of human life and the world depend, while between the two universes described by medical science and ethical-philosophical thought a window of opportunity for important psychological research is opened. In order to understand such phenomena the present article defends the theory that social psychology must adopt as its subject matter "thinking society," that is, society characterized by discussion and reasoning on themes relevant to bioethics.
