It is important to note here that Feenberg does not subscribe to relativism, which he rejects because of its false simplicity and its de-emphasis on action/agency. For Feenberg, there are clear distinctions between premodern and modern societies, however so far these distinctions have been made in a linear/sequential manner that see premodern societies as essentially non-technological and non-rational and modern societies as technological and rational. The alternative Feenberg proposes is to see rationality and cultural embededness not as alternative but instead as "layers" (aspects) of technology in all kinds of societies (premodern and modern ones). As Feenberg puts it, "there is no ëpureí technolgy anymore than there is ëpureí grammar. Technical competence, like linguistic competence, is realized only in concrete forms" (222). This means that in any society, technology, like grammar, embodies the fruits of normative consensus in aesthetic, ethical, and cultural domains; it is a cultural historical, social artifact, not the pure logical outcome of rationality (222).
