Agnosticism is a concept, not a full religion. It is a belief related to the existence or non-existence of God. ...
Agnosticism implies uncertainty about the existence of God. The basic problem here is that there are many answers to the question "Does God exist?" However there is only this one term available to cover all of the meanings. Some of today's possible overlapping answers to the question are:
* I don't personally know.
* I don't know but will lead my life in the assumption that no God exists.
* I don't know but will lead my life assuming that God does exist.
* I cannot give an opinion because there is no way that we can prove the existence or non-existence of God given currently available knowledge.
* I cannot give an opinion because there is no way to know, with certainty, anything about God, now and in the future.
* Yes, God exists. But we do not know anything about God at this time.
* Yes, God exists. But we have no possibility of knowing anything about God, now or in the future....
Three main meanings have been associated with "Agnostic" since Thomas H. Huxley invented the term in the mid-19th century
* Huxley defined agnosticism as follows: "... it is wrong for a man to say he is certain of the objective truth of a proposition unless he can provide evidence which logically justifies that certainty. This is what agnosticism asserts and in my opinion, is all that is essential to agnosticism." 11
* "... an agnostic is someone who not only is undecided concerning the existence of God, but who also thinks that the question of God’s existence is in principle unanswerable. We cannot know whether or not God exists, according to an agnostic, and should therefore neither believe nor disbelieve in him." 12
* An agnostic is undecided about whether or not God exists.
Are Agnostics also Atheists?
...Agnostics do not believe in ... Gods... However, some Agnostics consider themselves to be Atheists. That is because the term "Atheist" has two slightly different meanings:
1. A person who positively believes that no God(s) or Goddess(es) exists. ...
2. A person who has no belief in a God or Goddess. Just as a newborn has no concept of a deity, some adults also have no such belief. ....
Some Agnostics feel that their beliefs match the second definition, and thus consider themselves to be both Atheist and an Agnostic....
As currently defined, an agnostic usually holds the question of the existence of God open, pending the arrival of more evidence. They are willing to change their belief if some solid evidence or logical proof is found in the future. ...
Another category of Agnostic is "empirical Agnostics." They believe that God may exist, but that little or nothing can be known about him/her/it/them....
