Why Philosophia Buddhica? Even as someone who tries to do philology, one’s actual interest lies in philosophy. One does philology because one has to. One does philosophy because one likes it. The temptation, however, is that one does what one likes, but does not do what one has to. This seems to be particularly true in the field of Buddhology (i.e. Buddhist Studies). So honestly, I am sceptical about those of us who do (or rather try to do) Buddhist philosophy without relying on historical-philological works. Let us say all of us are interested in what the Buddha thought or said, what Nāgārjuna thought or said, and so on, but how are we to be sure that is what the Buddha actually thought or said and what Nāgārjuna thought or said. One of the greatest challenges thus is finding out if our attribution of a certain Buddhist philosophical idea to a certain person, a certain time, a certain place, a certain work, and so on, is accurate and thus reliable. None of us would, I would assume, prefer to live in a fool’s paradise! Because of such difficulties regarding past thoughts and ideas, we have no choice but to resort to historical-philological works, which may not always succeed in meeting these challenges but at least address these difficulties and draw caution to them. To be sure, historical-philological works are dreary and tedious, but that in way should suggest that we do not need them. In my view, a good student of Buddhist philosophy is also a good student of Buddhist philology, and vice versa. A student of Buddhist philology who does not understand Buddhist philosophy cannot do good Buddhist philology. A student of Buddhist philosophy who does not practise Buddhist philology cannot do good Buddhist philosophy. Of course, it is also a matter of personal interest. Not everyone who can do Buddhist philology or philosophy may want/like to do Buddhist philology or philosophy. This is an absolutely legitimate choice. But we should resist the temptation or tendency (in our academia, mostly those of us who are politicians in the academia) to denounce (or undermine) those fields or disciplines at which we are not particularly good at. The simple (il)logic seems to be: We do not need all those difficult disciplines at which I am not particularly good at. This is an apology for both Buddhist philosophy and Buddhist philology!
