Aikido or the concept of KI is man's way of thinking about the univers. It's his perception of the real world.
Though our perception is unique per person, we can't clame that the philosphi is unique. The thought is just what it is, and in it's concept unique, but it's only trying to describe something that is so common, but hard to describe.
So in the sense that what your trying to describe is "what life is", and "everbody" esle is doing the same, there is nothing unique in the philosophi of Aikido.
