| A Royal Institute of Philosophy Public Lecture                                        Abstract:                                                                                                                                          From
 Rumsfeld's 'Known unknowns' to Blair's Dossier, through to Trump's 
protestations of fake news, knowledge plays an important role in 
political narrative. Who knows what, and what can be known are key 
issues in those decisions which affect all our lives. Even when the 
claim to knowledge has been tenuous at best, there is an expectation of 
certainty -- we expect experts and politicians to know their stuff. In 
this talk we'll explore the space between knowledge as certainty, and 
knowledge as cultural in poststructural terms. We'll begin by examining 
the impact caused by philosophical doubt, uncertainty, and 
deconstruction, and end by asking whether philosophers have a role in 
reassuring others. For instance, by showing that there are some things 
we can know, and that these are the known knowns on which we can rely. |  |  |
