This paper provides an interpretation of trust and betrayal within political communities from the perspective of Husserl’s concept of social communities. I situate the paper amidst Margaret Gilbert’s theory of political obligations, arguing that at least one outside conception of trust fills a gap left in her theory. More specifically, I argue for the supplementary fit that Karen Jones’s conception of trust understood as ‘basal security’ provides for Gilbert. From there, I tie this conception of trust and betrayal to Husserl’s (...) notions of ‘original belief’ and socio-cultural crisis. There is thereby a phenomenological elucidation of features within the social world that allow such crises to occur in the first place. (shrink)
