 While contemporary philosophers, with some exceptions, have been slow to focus on corruption, the philosophical literature is increasing, especially in relation to political corruption. For instance, until recently the concept of corruption had not received much attention, and much of the conceptual work on corruption had consisted in little more than the presentation of brief definitions of corruption as a preliminary to extended accounts of the causes and effects of corruption and the ways to combat it. Moreover, most, but not all, of these definitions of corruption were unsatisfactory in fairly obvious ways. However, recently a number of more theoretically sophisticated definitions of corruption and related notions, such as bribery, have been provided by philosophers. Indeed, philosophers have also started to turn their minds to issues of anti-corruption, e.g., anti-corruption systems (often referred to as “integrity systems”), and in doing so theorizing the sources of corruption and the means to combat it.
