Cogito Part Deux

So maybe he did say it, Descartes I mean, "cogito ergo sum."  Or in French, "je pense, donc je suis."

Further research has turned up new possibilities.  I let the prof know.  I'm helpful that way. Last year, in the Religious Studies class I was taking, the prof decided to explain BC/BCE and AD/CE.

He began by saying, "Who knows what happened in the year 0?"

I said, "There was no year 0."

Always helpful.
