| Research Abstract |
The aim of this research project has been to trace the lines of development of the foundations of ethics, from the tradition of christian thought in late antiquity, through monastic theology and early scholasticism, emphasizing, then, high scholasticism, and concluding with the late middle ages; further, to analyze the structures of the various types of these ethical conceptions, and, finally, to clarify their sources as well as their roots in the mentality of their times. According to a research plan which combined individual and group research, the project concentrated on the important thinkers of the middle ages and investigated the central features and fundamental concepts of their various conceptions of ethics, tracing them back to their anthropological and ontological presuppositions, and, thus, succeeded to show tha fundamental unity of theoretical and practical philosophy in the middle ages.

human goodness, personal fulfillment and the common good of society, man's nature and moral law, man's happiness and his religious destiny, the objective norms of ethics and the ways of knowing them, the structure of the ethical object and the essence of free choice, justice and love as the fundamental ethical values etc. constitute a common horizon of the ethical thought of the middle ages, but in the ways of their solution and interrelation, the following widely differing types of their faundations of ethics have been discerned: 1. the immanent and formalistic ethics of Anselm of Canterbury, starting from an analysis of free will, 2. the existential approach of Peter Abelard, based on divine law, 3. the interpersonal ethics of Bernhard of Clairvaux, stressing the function of grace, and the conception of ethics in the framework of a theory of love of friendship in Aelred or Rievaulx, 4. the neoplatonic, contemplative conception of ethics as the way to spiritual perfection, in the school of St-Victor, 5. the christocentric ethical system, as developed by Bonaventure, 6. the foundation of ethics as a science in Thomas Aquinas, resting on the integration of Aristotle's ethics with theological anthropology, 7. the conception of fundamental ethics as an independent practical science, as it can be seen in Duns Scotus, 8. the intellectualist, ontological exploration of ethical problems in Meister Eckhart, 9. the attempt of restructuring the foundations of ethics on the basis of a voluntarist, theocentric nominalism, in William Occam.
