Under the necessity of expounding the translation by notes, I was not actuated by the ambition of being new, but only by that of being as useful as my means permitted, that is, by endeavoring to spare the reader time and trouble to look for dates and biographical notices of the persons, the situation of the places, and the explanation of the technical terms which occur in the text. Orientalists know the difficulty of rendering in a European language the phraseology of the Asiatic theology and philosophy. The Dabistán presents, besides the Sanscrit, a confusion of Arabic and Persian technical expressions; some of them have a very comprehensive signification, and for the sake of clearness must be rendered by different terms in different places; other expressions have at times a particular sense, and are at other times to be taken in the common acceptation; the same terms must be translated by different words, and different terms by the same; finally, the matter treated of is frequently so abstruse in its nature that professed philosophers have not yet been able to agree upon some of the most important questions. I can therefore but apprehend that I may not have thoroughly understood, and must confess that I have not translated, to my own satisfaction, more than one passage relative to Indian doctrines, and to the Muhammedan scholastic philosophy. The Sanscrit names and terms of Indian mythology, theology, and philosophy are much corrupted by the Persian spelling; I have endeavored to restore them to their original forms. I thought it right to adduce in most cases the Sanscrit, Arabic, or Persian word at the same time in Roman as well as Devanagari, or Arabic characters, with its interpretation. I followed the rule proposed by sir William Jones for writing oriental words in Roman characters, as often as I took these words from a Sanscrit, Persian, or Arabic text; but from works written in a European language, I was generally obliged to copy the spelling of Oriental names: on which account, in my notes, a regretable inequality of orthography could not be avoided. The Dabistán not only touches upon most difficult points of science and erudition, but also comprises in its allusions and references nearly the whole history of Asia. In observing this, I am necessarily at the same time pointing to the many deficiencies which will be found in my attempts to comment and illustrate so comprehensive and diversified a text. The best advantage which a man obtains at the termination of an arduous work, is to have enabled himself to make it better, if he could begin again; but he can but humbly submit to the decrees of an all-ruling power, which bestows upon each mortal only a certain measure of faculties and of time.
