>>The philosophers Hull and Ghiselin have done a fair bit to build on
Richard Dawkins characterisation of eveolution by selection processes.
Hull sums up: evolution requires *interactor* entities which form
*lineages* through *replication* to a variable degree of copying fidelity.
Hull has applied this to the evolution of science, and I am trying to
generalise this to any intellectual tradition for my Masters.
Boyd and Richerson have applied evolution to social change (with
questionable success IMHO), and Cafelli-Sforza (sp?) and Feldman as well.
However, if any progress is to be made in this area, it will only be if
semiotics is banned from all involvement 8-)
