Ethics, Sophistry and the Alternate Universe

From Memory Alpha, the free Star Trek reference

"Ethics, Sophistry and the Alternate Universe" was a philosophical book written by Ving Kuda sometime prior to 2366. The text was lengthy and would not ordinarily be considered "light reading". Despite this, Captain Jean-Luc Picard carried a copy of the book with him to Risa on vacation in 2366. (TNG: "Captain's Holiday")
