"The Selfish Gene" by Richard Dawkins: Review

Dawkins' insight can be summed up in two new terms—replicators, and vehicles. “Replicator” stands for are whatever it is natural selection works on to drive evolution. Vehicles are whatever the replicators reside in. Us, for example. In a single generation what natural selection selects for is the more successful individuals, but over vast numbers of generations it is the replicators within us, that account for our success, that natural selection picks out and judges for success in replicating. 

Does Dawkins make a value-judgment between replicators and vehicles? “…when you are actually challenged to think of pre-Darwinian answers to the questions ‘What is man?’ ‘Is there a meaning to life?’ ‘What are we for?’, can you, as a matter of fact, think of any that are not now worthless except for their (considerable) historic interest? There is such a thing as being just plain wrong, and that is what, before 1859, all answers to those questions were…. It requires a deliberate mental effort to turn biology the right way up again, and remind ourselves that the replicators come first, in importance as well as in history…. Their preservation is the ultimate rationale of our existence.” More...
