Extended knowledge, reliabilism and cognitive enhancement strategies

What is extended knowledge and what criteria should it meet? How does the category of cognitive enhancement influence its conceptualisation? Undoubtedly, the history of humanity involves a desire to exceed limits and overcome biological boundaries. As evidenced by research on the extended mind, human cognitive processes are largely dependent on the use of technological supports. The complementary concept of cognitive enhancement involves different strategies, from technological and behavioural to biochemical ones. Through their use, the conditions in which information is acquired are transformed, which entails the modelling of knowledge creation and acquisition processes. The aim of the article is to analyse and then unify diverse approaches pursued within reliabilist accounts of knowledge, concepts of the extended mind, cognitive enhancement and extended epistemology. Critical comments will also be considered, especially those concerning the concept of the extended mind and extended knowledge. This basis will be useful to define the essential criteria which, in the author’s opinion, should be met by extended knowledge.
