This chapter discusses the radically different takes to a viral theory of post-truth. Michael Peters explores fundamental philosophical questions about our current post-digital reality and develops the concepts of bioinformationalism, viral information, viral media and viral modernity. Truth relativism and judgemental relativism are now being weaponized by the Trump administration. Absent some ideal orator-citizen such as Cicero, critical educators can certainly counter the gaslighting philippics produced by Trumpland by engaging in a historical materialist rebuttal that enables us to utilize Hegel and Marx effectively in our attempt to engage the post-truth avatars at Fox News. Our approaches to a viral theory of post-truth could be further from each other; yet it is at their intersections that we can point together towards importance of developing the virologist perspective to our bioinformationalist reality into the future.
