I'm all for offending people's religion. I think it should be offended at every opportunity - Richard Dawkins

For his purposes (and mine), scientific medicine is defined as the set of practices which submit themselves to the ordeal of being tested. Alternative medicine is defined as that set of practices which cannot be tested, refuse to be tested, or consistently fail tests. If a healing technique is demonstrated to have curative properties in properly controlled double-blind trials, it ceases to be alternative. It simply, as Diamond explains, becomes medicine. Conversely, if a technique devised by the President of the Royal College of Physicians consistently fails in double-blind trials, it will cease to be a part of 'orthodox' medicine. Whether it will then become 'alternative' will depend upon whether it is adopted by a sufficiently ambitious quack (there are always sufficiently gullible patients).

bad things, like good things don't happen any more often than they ought to by chance. the universe has no mind, no feelings, and no personality, so it doesn't do things in order to either hurt or please you. bad things happen because things happen.

A system whereby each child told the parent how hungry he was would be ideal for the parent, and, as we have seen, such a system seems to have evolved. But the young are in a strong position to lie, because they know exactly how hungry they are, while the parent can only guess whether they are telling the truth or not. It is almost impossible for a parent to detect a small lie, although it might see through a big one.
