A little Latin

In 8th grade, I could select a language to study the following year.  German, French, Spanish or Latin.  I was intrigued by the chance to study Latin.   That choice guided me to the only city high school where I could get a 2nd year.  In the 2nd year, we read Caesar's Gallic Wars.  I learned the Latin word for "sheath": vagina.   What high school guy is going to forget that?

Yesterday, I wrote that I thought maybe my birthday caused Thanksgiving to occur.  I had noticed that the Pilgrims' holiday came after my birthday so maybe my birthday caused the holiday.  If I became convinced that was true, my thinking would be an example of a well-known logical fallacy that sometimes goes by the name Post hoc, ergo propter hoc ("After that, therefore because of that").  Sometimes, the name is shortened to "Post hoc". It is true that researchers often look for reliable phenomena that seem to relate to an event but hopefully they stay alert to the possibility that none of the correlates are causative.
