Common Sense Tells Us...

Bambrough's argument against moral skepticism is highlighted in The Ethical Life.  He argues five main points made by skeptics towards moral objectivity.  Overall, Bambrough relates that his argument is similar to that of G.E. Moore's.  Moore's argument consisted of proving the existence of an external world by pointing out he obvious.  He had two hands, these are both material objects.  Since there are at least 2 material objects; there is a materialistic, external world.

Can Ethics Be Objective? Analysis of Ethical Relativism

Can ethics be objective?  Russ Shafer-Landau analyzes this question, in The Fundamental Of Ethics, by critiquing the arguments of ethical relativism.   Ethical relativism is divided into two subtypes; cultural relativism and ethical subjectivism.  The cultural relativists argue that correct moral standards are decided by each culture or society (291).  In contrast, ethical subjectivists claim that each individual decides which moral standards are correct (291).  Landau tests each claim made by these theories through a series of logical tests. Although I will focus only on cultural relativism, the critiques of both groups' claims illustrate that their skepticism towards ethical objectivity is not plausible.
