Having established the basics of a Pascalian, “cordate” epistemology, this chapter explores the implications for how the world works and applications to some pressing problems today. The way the world looks, and so the reasons your experience gives you, depends on the state of your heart. But the fact that the world can be seen in these ways, according to the different states of heart, is a significant fact about it. Pascal infers much from this built-in ambiguity in the world when it comes to religion. That the world can be seen as both a Godless mechanism and mediating a loving relationship with God confirms one theology (the Augustinian Fall), and disconfirms the rest. A similar situation arises for us today, where the facts about the world can seem equally obvious to both sides of our polarized society, even though they are looking at the same world, albeit from their own “echo chambers.” This chapter explores the relevance of Pascal’s views on ambiguity to the deep disagreements we encounter in society today, applying insights about how the heart influences the way things appear as well as how to communicate with those who profoundly disagree with us.
