This chapter observes that philosophers often seem to form their opinions based on emotional reasons and only then seek purely neutral, theoretical reasons that support these opinions. Instead of renouncing such an approach, it is claimed that we should embrace it by dragging emotional reason for holding certain options into the open—and consider these emotions as evidence that can aid the discovery of truth. Drawing inspiration from William James among others, arguments from lived experience are understood broadly as cases where a thought is resonant, interesting, coherent, productive or exciting with regard to our personal life. Then, arguments from lived experience are defended against two charges: they are not merely a kind of “wish-fulfillment”; and the fact that our emotions obviously are products of evolution does not rule them out as evidence for truth. Finally, it is shown that the question of the existence of the past is especially well-suited for arguments from lived experience, because many aspects of our personal life are deeply involved with time and the past.
