Alienation has been recently revived as a central theme in critical theory. Current debates, however, tend to focus on normative rather than on explanatory issues. In this paper, I confront the latter and advance an account of alienation that bears on the mechanisms that bring it about in order to locate alienation as a distinctive social and psychological fact. In particular, I argue that alienation can be explained as a disruption induced by social factors in the sense of mental ownership (...) that comes with the first personal awareness of being a subject of attitudes, emotions, and actions, and outline how social factors can play a structuring causal role in the process that brings it about. In the first section, I introduce the theme and explain why it is important to focus on the mechanisms that underlie alienation. In the second section, I maintain that understanding how alienation works is crucial to make sense of false consciousness. In the third section, I consider the relevance of mental ownership to explaining alienation and discuss existing evidence about whether and how it can fail. In the final section, I argue that disturbances in the simulation routines that support social cognition might underpin alienation, and outline how social factors might play a structuring causal role in this connection.
