One of massage's biggest culture wars at present arises out of the dispute between monistic and dualistic philosophies. It has implications for how we practice with clients, and how we teach our students in our schools.
Although we're experiencing this culture war every day in our own field, this argument is centuries-old and is not limited to massage. Throughout human history, great minds have tried--and failed--to resolve it. I don't expect us to resolve it anytime soon, but we do need to resolve whether those of us on opposite sides of the philosophical divide can work together, or whether it divides us irreconcilably.
