Page "Ethics" Paragraph 11

At the turn of the 20th century, moral theories became more complex and are no longer concerned solely with rightness and wrongness, but are interested in many different kinds of moral status.

During the middle of the century, the study of normative ethics declined as meta-ethics grew in prominence.

This focus on meta-ethics was in part caused by an intense linguistic focus in analytic philosophy and by the popularity of logical positivism.
