Contributions to the Development of Tibetan Buddhist Epistemology, by Leonard W. J. van der Kuijp

The present paper is a considerably revised version of my doctoral dissertation entitled "Contributions to the Development of Tibetan Buddhist Logic - from the eleventh to the fifteenth century." This dissertation was submitted to the Faculty of Oriental Studies, University of Hamburg, in January of 1979. The title has been changed for two reasons. The first of these is a conceptual one. Namely, in the course of my subsequent studies of Buddhist tshad-ma (pramāṇa), I have decided to translate this fundamentally untranslatable term by 'epistemology'. While this rendition does also not do justice to its semantic range, I feel that it has at least the merit of being less misleading than the more widely used 'logic', especially for those who have no background in Indian or Tibetan studies, and who may chance to come across this title. It is and remains an untranslatable term.
      The second reason for my changing the original title of my dissertation, is that I felt obliged to change its scope. The vast literature on Tibetan Buddhist epistemology, which has become available during the last few years, necessitated such a curtailment. Especially the presently available Dga'-ldan-pa contributions by Rgyal-tshab-rje and Mkhas-grubrje, in particular, need to be properly assessed, and this takes time. Moreover, much but not all of the subsequent Sa-skya-pa literature in this area by Go-ram-pa and Gser-mdog Pan-chen must be read with the particular theories of these Dga'-ldan-pa philosophers in mind. To undertake such a comparative study cannot be done in a hurried fashion. Some references to the Dga'-ldan-pa contributions have, however, been made in the course of this paper on the basis of my original access to but a limited number of their writings. Nonetheless, a significant portion of my dissertation that deals with the fourteenth and fifteenth centuries, has been included in the footnotes of the present paper where I was concerned with historical or bio-bibliographical details.
