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.
