Are you rational if you trust your bank? Does the healthcare system deserve your trust? How should a state earn citizens' trust? In which sense do certain institutions need public trust in order to function properly? Is there a basic notion of trust common to both interpersonal and institutional dealings? How should we understand the so-called 'crisis of trust in institutions'? In Trusting Institutions, analytic philosophers address these and similar questions, which have been of central concern for social scientists for a while and are now increasingly at the centre stage in public debate. Careful conceptual scrutiny should clarify what it is to trust institutions and how this can be rational.
