Moralism is often described as a vice. But what exactly is wrong with moralism that makes it aptly described as a character flaw? This paper will argue that the problem with moralism is that it downgrades the force of legitimate moral criticism. First, I will argue that moralism involves an inflated sense of the extent to which moral criticism is appropriate. Next, I will examine the value of legitimate moral criticism, arguing that its value stems from enabling us to take (...) a stand against immoral behavior. Finally, I will argue that unwarranted moral criticism downgrades the force of legitimate moral criticism and that this is why moralism should be seen as a vice. (shrink)
