Public Ethics & Policy
Overheidsbeleid is vaak het onderwerp van alomtegenwoordige en diepe morele onenigheid. Morele onenigheid, gedefinieerd als het verschil tussen en verzet tegen principiële morele argumenten, kan voorkomen tussen beleidmakers, verschillende politieke partijen en individuen en het bredere publiek.
