My diploma thesis researches the concept of perennial philosophy (philosophia perennis, theologia prisca) and its development in the history of different cultures of the World. As I claim, the concept of Perennialism presents a useful means of understanding of different cultures distanced from us in time and space, including the history of the culture of ours. Perennialism shows, that Wisdom is not an exclusive property of just one civilization, but a common heritage of the Humankind as a whole. Further, it points to mutually beneficial influence of different cultures of the Globe. Throughout the paper, my focus lies on the development of philosophia perennis in the Islamic civilization, particularly on Sufism. Before being demolished by the rise of nationalism, the Sufist philosophy enabled a peaceful coexistence and dialog between different cultures and religions. The development of Perennialism is further studied in the philosophy of european Renaissance, where it was first tolerated by the Catholic Church, later to be abandoned, unfortunately (with few exceptions), during the Reformation and the Thirty Years' War. In the current pedagogical practice, the conception of philosophia perennis may become means of highlighting the common grounds of different cultures in the times of culminating...

Zwischen 1630 und 1650 vollzog sich ein Wandel in Athanasius Kirchers Vermittlung des musikalischen Wissens: Musik konzipierte er im Zusammenhang der Universalwissenschaft immer mehr als Zeichen des Weltbildes im Kontext einer christlich-neuplatonischen Pansemiose. Die Studie arbeitet dies am Beispiel der "Institutiones mathematicae" (ca. 1630), der "Mathematica curiosa" (ca. 1640) und der "Musurgia universalis" (1650) heraus. Besonderes Augenmerk gilt Kirchers Umgang mit seinen Quellen, insbesondere Nikolaus von Kues, Robert Fludd und der Tradition der Philosophia perennis. / Between 1630 and 1650, a change in Athanasius Kircher's way to communicate the knowledge of music took place: Within the context of universal science, he conceptualised music increasingly as a symbol for his world view and its Christian-Neoplatonic pansemiosis. This study discusses these issues based on Kircher's "Institutiones mathematicae" (c1630), "Mathematica curiosa" (c1640), and "Musurgia universalis" (1650). Special emphasis lies on Kircher's use of his sources, particularly Nicholas of Cusa, Robert Fludd, and the tradition of Perennial philosophy.

The notion of identity has always been central to the human person's understanding of self. The question "who am I?" is fundamental to human being. Answers to this question have come from a wide range of academic disciplines. Philosophers, theologians, scientists, sociologists and anthropologists have all sought to offer some insight. The question of individual identity has traditionally been answered from two broad perspectives. The objectivist approach has sought to answer the question through empirical observation - you are a mammal, you are a homo-sapien, you are male, you are African etc. The subjectivist approach has sought to answer the question through phenomenological exploration - I understand myself to be sentient, I remember my past, I feel love etc. A recent development in the field of computer science has however shown a shortcoming in both of these approaches. Ray Kurzweil, a theorist in strong artificial intelligence, suggests the possibility of an interesting identity crisis. He suggests that if a machine could be programmed and built to accurately and effectively emulate a person's conscious experience of being `self' it could lead to a crisis of identity. In an instance where the machine and the person it is emulating cannot be either objectively distinguished (i.e., both display the same characteristics of the person in question), or subjectively distinguish themselves (i.e., both believe themselves to be the `person in question' since both have an experience of being that person. This experience could be based on memory, emotion, understanding and other subjective realities) how is the true identity of the individual validated? What approach can be employed in order to distinguish which of the two truly is the `person in question' and which is the `emulation of that person'? This research investigates this problem and presents a suggested solution to it. The research begins with an investigation of the claims of strong artificial intelligence and discusses Ray Kurzweil's hypothetical identity crisis. It also discusses various approaches to consciousness and identity, showing both their value and shortfall within the scope of this identity conundrum. In laying the groundwork for the solution offered in this thesis, the integrative theory of Ken Wilber is presented as a model that draws on the strengths of the objectivist and subjectivist approaches to consciousness, yet also emphasises the need for an approach which is not only based on individual data (i.e., the objectivist - you are, or subjectivist - I am). Rather, it requires an intersubjective knowing of self in relation to others. The outcome of this research project is an African Theological approach to self-validating consciousness in strong artificial intelligence. This takes the form of an African Theology of relational ontology. The contribution falls within the ambit of Christian anthropology and Trinitarian theology - stressing the Christian belief that true identity is both shaped by, and discovered in, relationship with others. The clearest expression of this reality is to be found in the African saying Umuntu ngumuntu ngabantu (A person is a person through other persons). / Systematic Theology / D. Th.
