«What is clear is that values can clash. Values may easily clash within the breast of a single individual. And it does not follow that some must be true and others false... the notion of the perfect whole, the ultimate solution in which all good things coexist seems to me not merely unobtainable -- that is a truism -- but conceptually incoherent. Some among the great goods cannot live together. That is a conceptual truth. We are doomed to choose, and every choice may entail an irreparable loss.»
Isaiah Berlin
