What is the right definition of agnostic?

[pocaracas]

Oh.... your beef is with the dictionary?
LOL... never use the Merriam-Webster, then! That thing is biased.

But there's a decent online dictionary that I've found to be complete on most things:
http://www.dictionary.com/browse/agnostic?s=t

noun
1. a person who holds that the existence of the ultimate cause, as God, and the essential nature of things are unknown and unknowable, or that human knowledge is limited to experience.
Synonyms: disbeliever, nonbeliever, unbeliever; doubter, skeptic, secularist, empiricist; heathen, heretic, infidel, pagan.
2. a person who denies or doubts the possibility of ultimate knowledge in some area of study.
3. a person who holds neither of two opposing positions on a topic:
Socrates was an agnostic on the subject of immortality.


adjective
4. of or relating to agnostics or their doctrines, attitudes, or beliefs.
5. asserting the uncertainty of all claims to knowledge.
6. holding neither of two opposing positions:
If you take an agnostic view of technology, then it becomes clear that your decisions to implement one solution or another should be driven by need.


Origin of agnostic
Greek
< Greek ágnōst (os), variant of ágnōtos not known, incapable of being known ( a- a-6+ gnōtós known, adj. derivative from base of gignṓskein to know) + -ic, after gnostic; said to have been coined by T.H. Huxley in 1869

At least one of those should describe what you want.



EDIT:
Also, for difficult matters, there's a better dictionary (well, it's actually an enciclopedia.... the "Stanford Encyclopedia of Philosophy"):
