 Griffith’s ideas have been criticised based on perceived problems with the empirical veracity of his anthropological writings, an objection that highlights his reliance on the writings of the African novelist Sir Laurens Van Der Post, and also the work of anthropologist Elizabeth Marshall Thomas.Griffith has argued throughout his writings that the driving force in human evolution was increased nurturing of offspring, a process he calls 'love indoctrination'.He adopts a neo-Lamarckian view in which mothers model pro-social behaviour to offspring, with consequent behavioural changes resulting in 'soft' Lamarckian inheritance.
