The logic of Agnosticism
In order to understand the logic of the position adopted by agnostics, it is necessary to understand the correct parsing of statements of belief or knowledge. Such statements are not about facts, but about other statements. In the jargon of the logician, they are second-order predicates.
There are two possible statements as to the facts – either God Exists or God does not exist. Since X can either agree or disagree with each, there are a total of four possibilities:
- X agrees with the statement: God Exists
- X does not agree with the statement: God Exists
- X agrees with the statement: God does not exist
- X does not agree with the statement: God does not exist
Joining these with a conjunction, one can derive four possibilities:
1. The Theist agrees with the statement God Exists AND does not agree with the statement God does not exist
2. The (strong) Atheist does not agree with the statement God Exists AND agrees with the statement God does not exist
3. The Agnostic (or weak atheist) does not agree with the statement God Exists AND does not agree with the statement God does not exist
4. But one cannot agree with the statement God Exists AND agree with the statement God does not exist, since it implies agreement with the statement God Exists & God does not exist. Similarly, the agnostic position implies that the agnostic does not agree with the statement God Exists & God does not exist.
It is clear that the agnostic position is an intermediate between strong atheism and theism.
There are two other points to note. The first is that it is unnecessary to draw a distinction between belief and knowledge; to claiming agnosticism is about knowledge, while atheism/theism is about belief. This is a furphy, since knowledge implies belief – one cannot intelligibly KNOW that X and not also BELIEVE that X.
The second is that it is not true that the presence of a belief in a god and the absence of a belief in a god exhaust all of the possibilities. There are four, not two, possible positions.
