Well, that's one reason I don't like the term "agnostic". I know original meaning; that theists could never actually understand the nature of God.
Without looking up Huxley's exact words, I don't think that's how he defined agnosticism. I'm pretty sure he meant, "God's existence is unknowable." But there is an example of the imprecision of perception. Even knowing the original meaning, we both interpret it differently.
As an atheist, I find both meanings annoying. The first because it assumes there is a god.
See, I don't think that Huxley assumed any such thing.
The second because it describes a position that all must have in a certain way.
Agreed, and this is my biggest rub with the colloquial definition. Not only do we not have the same position in the same way as theists, but the bigger issue is that we arrive at conclusions and beliefs in an entirely different way, using entirely different processes.
Granted, some atheists don't use the rational process either, even ones who make no positive claim that a "God does not exist." But a rational process is important, and Huxley's agnosticism is central to that process. We need to understand what we cannot know, so we can stop wasting our time in rational inquiry about it, at least until such time as it becomes knowable.
I don't much try to prove there isn't a deity of some sort somewhere anymore (negative proofs and all that nonsense). But equally given no evidence, I choose to think the deity-concept both ridiculous and unnecessary for any purpose of the universe.
Atheism means having no thesistic belief, and I have none. If some deity creted the universe in a finger flick and left, and then came back tomorrow saying "remember me?", I would not be logically shocked.
I WOULD be highly annoyed and dismayed. Shocked even. But I consider the likelihood of that seriously minor-to-vanishing.
See, we are very much of the same mind. We are having a semantic quibble. I usually avoid discussions of semantics, but this issue attracts my attention, and I'm not entirely sure why it's so important to me.
Perhaps, because the realization that I could not know was one of the bigger insights in my journey to atheism. It was life changing and marks an important milestone in my personal growth.
Life long atheists might not see such an insight as anything so important, because they were never in a quagmire of irrational spirituality to begin with. They never had to climb out of the hole, so to speak.
