Oh heck I just used "Transubstantiation" as an example. The Catholic church has a doctrine that the communion wafer actually becomes a piece of Christ's flesh. To make the idea seem less silly, they give it a fancy name! I would argue that some words in the philosophy of consciousness - such as epiphenomenalism serve a similar role!
Miguel - tell me you are not a Catholic!
Let's not sidetrack this thread on the very first page - because I think the question of how science could explore the non-physical is important!
