This paper has two distinct objectives. (1) I defend an analysis of th
e concept of a conflict of interest. On my analysis the concept of a c
onflict of interest is broader than is generally supposed. I argue tha
t a very large class of cases not ordinarily regarded as conflicts of
interest should be so regarded. Conflicts of interest are an integral
feature of many professional relationships and do not (as is often sup
posed) require the existence of ''external'' financial or personal rel
ationships. (2) 1 defend and explain the common-sense view that confli
cts of interest are prima facie wrong and argue that in ordinary cases
it is wrong, all things considered, to allow an avoidable conflict of
interest to occur. I attempt to establish these claims on the basis o
f weak and relatively noncontroversial assumptions.
