From Tractatus

You chose as your high level domain as a homage to the Tractatus Logico-Philosophicus [1] by Ludwig Wittgenstein.

When you first started becoming interested in Logic you decided to read this guy because by reputation he was logical in his presentation of his Weltanschaung. So, you went to the 4th floor of Pattee Library, and read it for a few hours. I remember liking it.
