"What reasons are there for accepting synchronicity as an explanation for anything in the real world? (My italics). What it explains is more simply and elegantly explained by the ability of the human mind to find meaning and significance where there is none (apophenia)." - Robert Todd Carroll from The Skeptics Dictionary.

By real I expect Mr. Carroll suggests definable or measurable by scientific method. If it can't be measured it doesn't exist, right Mr. Carroll? I looked up the word "apophenia" and found no entries in two online dictionaries. Is it even a real word? I think it is very appropriate that the web address for the Skeptics Dictionary is "SkepDic.com". I couldn't have put it better myself.
