This is a graphic we have been wanting to do for some time. Our artist, Gerald Stratton, had created this composite consisting of one of the designs we purchased, some years ago, from Tom Rieschick combined with a paraphrase of René Descartes' self-convincing proof of his own existence, "I think, therefore I am" (Cogito ergo sum*). We are most grateful to our fellow Cincinnatian, and good Sherlockian friend, Dan Andriacco, for his coaching in the identification of the proper third person perfect tense of the Latin verb cogitare (to think) so that we could have Holmes saying, "He (Doyle) thought therefore I am." (Our own Latin is more than a little rusty!)We thought that this graphic would lend a certain  je ne sais quoi to what might otherwise be quite ordinary wearing apparel, hence, the good folks at CafePress have created for us a T-shirts (click here to see) and sweatshirts (click here to see) bearing this graphic. We like it and that's why we (and Dan Andriacco) quite often wear our "cogitavit" sweatshirts and T-shirts. What do you think your Sherlockian friends will say when they see you wearing your own "cogitavit" shirt?

*Some authorities have said the Decartes quotation is actually, "Dubito, ergo cogito, ergo sum" (I doubt, therefore I think, therefore I am), but the quotation is most often cited as simply "cogito ergo sum."
