I refer to Oderberg's use of Elliott Sober's and Mark Ridley's work to make statements about cladistics:
- "See also Sober 1993:Ch. 6 for a defense of cladism and criticism of competing methods" (Oderberg 2008: 214).
- Ridley is a little less sanguine about the implications of cladistics ..." (Oderberg, 2008:222).
- "Ridley notes briefly that [t]here is no orthodoxy among evolutionary biologists [I take him to mean mainly cladists] ..." (Oderberg, 2008:222).
- "So it looks like the cladist has to believe in the existence of inorganic evolutionary descent at every stage in the past history of the universe" (Oderberg, 2008:220).
- "Common sense - which is not, as I will argue, the same as cladistic sense ..." (Oderberg, 2008:215).
- Another bizarre consequence of cladism is the following (LaPorte 2004: 50-62; Okasha 2002: 205-7)" (Oderberg, 2008:220).
- "Yet this absurd result of cladistics is accepted by LaPorte with equanimity, and taken by Okasha (2002: 205-7) at face value since he upbraids essentialists ..." (Oderberg, 2008:221).
