As I emphasized in Death and the Afterlife, there is a conservative dimension to valuing, something approaching a conceptual connection between valuing something and wanting it to be sustained and to persist over time.
Maybe it's not Scheffler's responsibility, but I wish I had his take on the relation to value conservatism and political conservatism. Or at least directed to something. Like surely political conservatism was value conservatism gone wrong... right? EDIT: Brought up in Chapter 5. Not exactly in the way I was hoping, though.
