The Unity of all Things
One of my tightly held philosophical belief is the unity of all things i.e. that all things, despite our tendency to differentiate things, are essentially part of the same thing (just different forms).
One interesting thing about listening to Radio NZ on Saturday afternoons is that they play a plethora of different music, from hip-hop to country, to house music to metal etc. Usually music tends to get a little tribal - especially if you are younger. It is perhaps when you become musically wise when you realise that music cannot be chopped up. It does have different forms but it remains an intact art. It is a unity. It is then you can listen to almost anything.
