Regarding most of the lengthy examples of "philosophy" given by Stove:

Reading a text takes time, time can be spent acquiring utilions. Hence reading a text is only worth if the expected utilion win due to additional knowledge is grater than the expected utilions when using the time differently. This approach kills most of his examples dead in their tracks for me. This also implies positivism, if a text does not either generate utilions directly, i.e. fun reading fiction, then it needs to provide knowledge (in form of testable statements about the world), otherwise, how would I generate utilions from the "knowledge"?

Possibly, some thoughts are only valuable when more efficient methods of communication become available.
