Maybe you lot are right - I know at the time, although I wasn't actually looking for a 'philosophy', I had started to realise that much of Western philosophy just become arguments about terms, language and predjudice and there really wasn't any point of a lot of it. I think most Eastern philosophies (and some very rare western philosophers) are very different to what Westerners would consider philosophy - and it is possible it was this little gap in my experience which the aikido philosophy fell in to.
P.S. Ed, I was thinking more of the psycholgical/philosophical rather than metaphysical/physical aspects (e.g. ki), but I'm sure they are related as my aiki tends to be better when I'm in a friendly and happy state of mind. (probably relaxes meand I'm more sensetive to uke and observant).
