title: [Science in the crosshairs of enlightenment. Significance of hypothetical thinking].
abstract: To further the enlightenment primarily or even only by means of science was the hope of most representatives of the movement of the enlightenment which gave its name to a whole period of European cultural history. Only a few of its representatives, like Montesquieu and Rousseau, doubted for good reasons, whether and how the goals of the enlightenment can be reached at all by the means of science alone. In his Discours préliminaires to the Encyclopédie D'Alembert still wanted to limit science proper to the narrower field of those kinds of research which were strictly based on observations and calculations alone. In this way he remained committed to Descartes' ideal method of receiving authentic knowledge only by deduction from evident axioms or fundamental theorems. Pascal's casual discovery of the calculation of probabilities allowed to apply mathematics on the hidden laws of the apparent casualties of the human life world. Bacon's project of empirical science as a rational and methodological art of conducting experiments could replace the methodological ideal of science more geometrico. Lichtenberg's refined sensibility for the subjunctive linguistic forms of hypothetical thinking indicates a new understanding of inventing and testing hypotheses as the two most important methods of the experimental sciences when compared to the formal sciences of logic and mathematics. Whoever is studying the history of science of modern times in the cross wire of the enlightenment, will realize soon that science has always been in need of being illuminated about its own chances, risks and side effects. The project of enlightenment through science had to be complemented by the project of an enlightenment about science right from its beginning. Because of the implicit risks and side effects the project of enlightenment has to be enlightenment despite of science and because of science. On the one hand, as a special form of human practice the sciences are directed towards theoretical goals and practical purposes such that their agents cannot be conscious of all aspects of their practices in advance and reflect about all of them at the same time. On the other hand, the agents of such scientific practices are rarely trained, to analyze the cognitive implications of their own actions with the conceptual means of philosophical analysis. Furthermore, the agents of scientific research are hardly able to foresee the theoretical results of their research or even predict the chances and risks of eventual applications with the methods of the social sciences. Despite of the chastening experiences with the ambivalence of the theoretical results and practical applications of the modern sciences and despite of the illuminating effects of modern history and theory of science, contemporary scientists are not fully conscious yet of what they are really doing and what science really is. The contemplative ideal of scientific investigations for their own sake has been replaced in modern times by the practical ideal of scientific research in the service of humanity. The emancipation of the modem sciences from philosophical authorities and religious institutions has freed at first the sciences from alien restrictions to their self-chosen objects and purposes of research. However, the increasing economic constraints and the political dependences prevented even more so that scientists could realize the autonomy which the representatives of the enlightenment had been hoping for. KANT defined the goal of enlightenment as "man's emergence from his self-incurred immaturity". Quoting HORACE'S Sapere aude! he appealed to the courage of his comrades to use their own reason without the guidance of others in philosophical and especially in religious matters. Intellectual maturity as the proper goal of the enlightenment remained to be an undelivered promise despite of the emancipation of the sciences from traditional philosophical authorities and religious institutions. It is not only arguable whether or not enlightenment in this understanding is possible for most people, but also whether it is even desirable for all people considering the implicit ambivalence of the modern sciences. Kant's main philosophical works can be adequately interpreted as the first and unique attempt to understand the potential of the cognitive capacities of human beings about the chances and risks of enlightenment itself by means of a critical inquiry. This holds especially for the practical fruits of the enlightenment as, e.g., with respect to the emancipation from superstition and the appeal to religious tolerance, to the republican idea of the state and the establishment of civil and human rights, to the humanization of the law and execution of legal penalty as well as the unalienable rights of each individual human being.
