I'm wearing my Thinker tie on 12 November to celebrate the birthday of sculptor Auguste Rodin (1840-1917). I've placed my tie bar to show him contemplating the words "Walkabout Expert," related to one of my favorite activities with my young grandchildren!

I think today is one of the best days to think about philosophy! I am honoring the birthday of David Hume (1711-1776) and Ludwig Wittgenstein (1899-1951), two of my own heroes in philosophy. Hume's demands for empirical evidence rather than superstition and mysterious forces became a major factor in the development of experimental science as we know it today. Wittgenstein studied language, working out many of the rules of the "games" we play to connect words into meaningful strings (statements). By the way, today is also National Pretzel Day, National Richter Scale Day, and the birthday of Carol Burnett (1933).

It's a great day for thinking! Around 1641 French philosopher René Descartes created his famous "Meditations on First Philosophy," including his ruminations on being a "thing that thinks." Today I am co-presenting (with Laura Newhart) a discussion of Sentient Artificial Intelligence and Personhood, the most current expression of the age-old conundrum "Can machines think?" (My own simplistic answer is "Of course! I do it all the time!") Our stimulus is the report in June 2022 by Google engineer Blake Lemoine, claiming that his conversations with an artificial intelligence system named LaMDA proved that the AI entity had genuine feelings and wanted to be treated as a person. Laura and I are particularly interested in thinking about our (human) responsibilities and options when AI systems develop ever-greater sentience and increasing evidence of consciousness.

Today (12 November) marks the birthday of sculptor Auguste Rodin (1840-1917). My tie shows his most famous statue, The Thinker. My Outlook calendar suggests that I wore it first for Rodin's birthday in 2006, a year and a half before I started my tie blog. Today I'm also a presenter for the 2020 Kentucky Convergence Conference, an annual celebration of educational technology. The conference is 100% online and so I made my own badge.

- He who learns but does not think, is lost! He who thinks but does not learn is in great danger.
- If you think in terms of a year, plant a seed; if in terms of ten years, plant trees; if in terms of 100 years, teach the people.
