Today we celebrate Paul Nelson Day in honor of the five year anniversary of his theory of “ontogenic depth” and a promised exposition that has never appeared. Methods of celebration vary – PZ has in the past suggested that we should make it a point to ask people “How do you know that?” today, and the ones who actually can explain themselves competently will be complimented by being told that they’re no Paul Nelson. I have suggested that you can invent a new concept (such as “ontogenic depth”) and promise to explain it later.
No matter how you choose to celebrate, have a happy Paul Nelson Day!
