vABSTRACT: The article aims to provide an examination of some different arrangements of the Philosophy
domain in bibliographic classification systems. It is difficult to organize the scientific field of Human Sciences, because
of the richness of perspectives, and of the different cultural orientations that this broad field of science presents. Furthermore,
it is really arduous to organize the scientific field of Philosophy using a traditional classification system. It is hard to accommodate
philosophical knowledge—-elaborated inside different cultures. In many cases not compatible with each other—in a
classification system created by a particular cultural system, because it depends on that specific cultural approach. General
principles of bibliographic classification and also differences noticed when these are compared with the principles and laws of
logical classification, are discussed. In contrast, the fact that library classifications are influenced by ideologies and political orientations,
and that they are substantially arbitrary, is pointed out. In the second part of the study, the Dewey Decimal Classification
{DDC) and the Bliss Bibliographie Classification second edition [ßC2) are analysed, and at last the suggestion of BC2 to
consider philosophical problems and topics in connection with cultural tradition, ethical and religious principles, and also political
and social structures, is evaluated.
