Sometimes will have to be my best answer.
I suppose it could be worse…
Since different very smart people reach contradictory truths, I’m not sure we ever get to a Truth…other than mathematics.
Well, given that, we can be sure of some other facts. For example, that sometimes people do disagree (or, if you want to be extra careful, that they appear to disagree). And that this fact needs an explanation.
And the possible explanations are not numerous. Either the contradictions between opinions are real or just apparent. If they are real, then either opinions are all true, though contradictory, or some are false. And if some are false, then either unimpeded human reason can reach truth, or it cannot. Thus the four possibilities:
- Contradictions between opinions are only apparent.
- Reality itself is contradictory.
- Unimpeded human reason can reach truth, but it is often impeded.
- Unimpeded human reason cannot reach truth.
Of those, first and second are too obviously silly, thus people usually do not even try to claim to believe them. That leaves third and fourth.
So, what happens if you choose one of them?
If you choose the third one, we conclude that human reason has been impeded in many ways. By laziness, by cowardice, by pride, by ignorance (or “knowing” falsehoods), by inattentiveness… And, most likely, that applies to your reason as well. Therefore, you have to fight all those impediments. And before you can do that, you have to look for them and admit them when found, which tends to be unpleasant. But if you do all that, a “prize” awaits you: truth.
And the fourth option avoids all this hard work. If human reason cannot reach truth anyway, there is little point to look for ways in which your reason is impeded, admit them, fight them. You can believe you are smart and wise and knowledgeable and so on. But in that case, you can’t help anyone else reach the truth, nor can anyone else help you. One can only show off. Yet there is little reason to admire someone like that. Only to use him as an example.
and if the Church agrees with them then they aren’t teaching their members what that is.
I specifically referred to the very first example you gave, which, at the very least, is not
obviously contradicting teaching of the Church.
I lost belief in God first. I continued to practice my faith trying to get my belief back. It was years later that I finally told myself that I had no faith left and accepted it…
I find it pretty likely that you felt you no longer believed. I find it far less likely that you truly did not believe at that time.
I can’t help but notice that you didn’t answer the question. If two people both use logic and reason to come to different conclusions, how do you determine which one is being rational, and which one isn’t?
I can’t help but notice that you act as if you think I should answer it, but did not yet explain why it would be so.
