I may have also missed giving the proper suggestive links in many places where condensation was inevitable and the systems themselves have also sometimes insoluble difficulties, for no system of philosophy is without its dark and uncomfortable corners. Though I have begun my work from the Vedic and Brâhma@nic stage, my treatment of this period has been very slight. The beginnings of the evolution of philosophical thought, though they can be traced in the later Vedic hymns, are neither connected nor systematic. x More is found in the Brâhmanas, but I do not think it worth while to elaborate the broken shreds of thought of this epoch. I could have dealt with the Upani@sad period more fully, but many works on the subject have already been published in Europe and those who wish to go into details will certainly go to them. I have therefore limited myself to the dominant current flowing through the earlier Upani@sads. Notices of other currents of thought will be given in connection with the treatment of other systems in the second volume with which they are more intimately connected. It will be noticed that my treatment of early Buddhism is in some places of an inconclusive character. This is largely due to the inconclusive character of the texts which were put into writing long after Buddha in the form of dialogues and where the precision and directness required in philosophy were not contemplated. This has given rise to a number of theories about the interpretations of the philosophical problems of early Buddhism among modern Buddhist scholars and it is not always easy to decide one way or the other without running the risk of being dogmatic; and the scope of my work was also too limited to allow me to indulge in very elaborate discussions of textual difficulties. But still I also have in many places formed theories of my own, whether they are right or wrong it will be for scholars to judge. I had no space for entering into any polemic, but it will be found that my interpretations of the systems are different in some cases from those offered by some European scholars who have worked on them and I leave it to those who are acquainted with the literature of the subject to decide which of us may be in the right. I have not dealt elaborately with the new school of Logic (Navya-Nyâya) of Bengal, for the simple reason that most of the contributions of this school consist in the invention of technical expressions and the emphasis put on the necessity of strict exactitude and absolute preciseness of logical definitions and discussions and these are almost untranslatable in intelligible English. I have however incorporated what important differences of philosophical points of view I could find in it. Discussions of a purely technical character could not be very fruitful in a work like this. The bibliography given of the different Indian systems in the last six chapters is not exhaustive but
