In Star Trek people are beamed from place to place using transporters (their molecules are converted into energy which is then beamed to another place where it is turned back into the original people), even though logic dictates that if so then people should not eat food, whereas in Star Trek they do eat food. The logic is as follows: When people eat they replace some of their molecules with ones from food, so that we can easily imagine that all their molecules are replaced, with the old ones being crapped out. If that crap was collected and its atoms rearranged into an exact copy of those people, then that would be just that: copies. So, if that is how things are, then transporters would kill people and create copies of them.
I am old; in 2003, at the age of 40, I was published in the British Journal for the Philosophy of Science, but since then I've done little. Blogging since 2007, my main involvement was via the Philosophers' Carnival, which moved to Facebook.
