You touched on some important philosophies. How do you know what is actually blue? Well, you can't. I can only know (through the world of phenomoenona) that what I see as blue, is blue. I cannot know what everyone else sees as blue. We could all be pointing at the same thing and calling it blue. But I can't know if they're seeing the same blue as me. Thats ...[text shortened]... ead on it, but it seems to have degenerated into a "My Gods better then yours" debate.
From Wikipedia:
Blue is any of a number of similar colors. When it is a pure color from a single source, it corresponds with a wavelength range of about 420–490 nanometers.
There are definitions for blue, if one is misleadingly interpreting any (significantly) different wavelength range than it is he who is making the mistake.
No ambiguity there, even if one cannot know if your brain processes the information of the colour blue differently.
The interesting thing is that it doesn't matter! The inability to project oneself into another person's consciousness doesn't prevent that blue can be defined accordingly and consensually, even if there is the possibility of the brain processing of the colour blue being radically different. A blind person can be made to understand the physics of a colour and wouldn't that individual know more about the colour than the average person who can actually see (but doesn't truly understand)?
One should be careful when applying such metaphors to the physical world.
My atheism comes from a form of skepticism. As far as I do not see evidence towards the existence of a creator, I will remain so. The belief on faith is contradictory to skepticism but my support for skepticism is a belief in itself (that it leads to less extremisms) but based on induction, not faith. I leave to you to discern if it is contradictory or not.
But can anyone have an ideology without any axioms? It is my opinion, that they cannot.
