Does Atheism Lead to Nihilism?

[Esquilax]

G. E. Moore argues that you cannot define good (like you can a chair)...
...we cannot define "good" by explaining it in other words. We can only point to an action or a thing and say "That is good." Similarly, we cannot describe to a blind person exactly what yellow is. We can only show a sighted person a piece of yellow paper or a yellow scrap of cloth and say "That is yellow."

G.E Moore was fucking wrong, brother: if you can't have a definition of good then what the hell were you using to determine that the action you're pointing to was good?

Similarly, we actually can define yellow, just not in points of reference that a blind person would be familiar with. You have to have some idea of what yellow is before pointing to it, else how would you know what you're pointing at is yellow?
