This introduction to the special issue consists of some arguments that are intended to fold the concepts 'ethics' and 'politics' into one another. The aim of this exercise is to take business ethics to task for having a narrowly 'ethical' view of its ambitions. Instead, I propose that business ethics needs to embrace political theory in addition to the moral philosophy that it has treated as canonical. I argue that such an enlargement will encourage those who currently practise business ethics (...) to ask broader questions about the current legitimacy crisis facing market managerialism, and also seriously to consider alternative forms of organization and exchange. The paper concludes with a short review of the rest of the issue. (shrink)
