This paper, at the crossroads of practical and epistemological questions, puts forward a non-standard approach to the study of a set of trust phenomena (trust, trustworthiness, distrust, self-trust, self-distrust...) and their interconnectedness. Two paradigmatic approaches to trust – harmonic and disharmonic – are unpacked and shown to be com-plementary. In contexts where the harmonic view applies, trust phenomena are mutually reinforcing. When the disharmonic view is appropriate, instead, they counterbalance one another. An analysis of Augustine’s De fide rerum quae non videntur helps introducing the former. Each view carries its own conception of the role of institutions in trust. For the harmonic approach, institutions are contexts that reinforce trust silently, whereas for the disharmonic view they are salient objects of trust. The need for an over-arching articulation of these limited views is further highlighted by appeal to another distinction, between background and decision-based forms of trust. This paves the way to what is here termed a metaharmonic theory of trust, a theory sensitive to the difference between the contexts where trust phenomena reinforce or counterbalance one another.
