I'm not sure ... a little out of my depth here
But it would seem to me we should be able to say
1/O (AB) > 1/O (ABC)
Because O (ABCDEF..........) should approach 1? |

I see what you are saying now. I totally misunderstood and misused your sysmbolism. I agree that O
(ABCDEF..........) should approach 1 and that 1/O
(AB) > = 1/O
(ABC)
Still, if the simpler conclusion is contained in the more complex conclusion
then we can say that the argument with the simpler conclusion is more likely to be true than the argument with the more complex conclusion.
In this case if we had additional axioms that came into play, they would either lead to both conclusions or just the simpler conclusion.
For instance, say that axiom D (prob. 1/s) and axiom E (prob. 1/t) also implied that the conclusion based on axioms A and B. Then the probability that the conclusion is true would become 1/xy + 1/st.
And if any axioms F (prob. 1/n) and G (prob. 1/m) increased the conclusion based on axioms A, B and C to 1/xyz + 1/nm, it would also increase the probability of the simpler conclusion to 1/xy + 1/st + 1/nm.
So the probability of the simpler argument would always remain higher than the more complex argument no matter how many unknown axioms may come into play.
An rough example of two arguments with this relationship would be;
1. Objects in moving in a straight line continue to do so unless acted on by an external force.
2. The planets orbit around the sun.
3. Therefore a force is exerted on the planets.
1. God is the cause of all things.
2. Objects in moving in a straight line continue to do so unless acted on by an external force.
3. The planets orbit around the sun.
4. Therefore the god causes a force to be exerted on the planets.
I'm sure there is a better example but I am getting lazy.
What do think? Are there any flaws?
