"The difference between your belief in your religion and my belief in science is that science would be true whether I believed in it or not." I've seen this statement made again and again whenever a religious person states that scientific thought is nothing more than a matter of mere belief. It isn't, of course. The laws and principles discovered though scientific inquiry would still hold true despite our acceptance or disbelief in them.
What I would say that is closest to your quoted sentence is that the difference between the belief in gods and angels and a belief in scientific principles is that the former is unjustified belief, and the latter justified.
there is a scientific method by which scientific truth is verified. Nobody (I hope) would argue that that a scientific theory would have to not only pass such a rigorous scientific testing, but also pass some kind of religious test in order to be called truth. (Well, Mr. Scientist, your theory of X is really quite nice, and you've nailed the science part. But, I'm sorry to say, you've failed to prove it according to religious standards, so I'm afraid we can't call it true.) Rather silly, right? Think about it from another angle, though. (Well, Mr. Religionist, your belief in X is really quite nice, and you've nailed the religious part. But, I'm sorry to say, you've failed to prove it according to scientific standards, so I'm afraid we can't call it true.) Why do many feel that this isn't just as silly? If science if true regardless of what religion has to say about it, then why can't religion be true without the imprimatur of science?
I don't make a distinction between scientific truth and religious truth. There is only truth, truth being the quality that facts possess, and facts being linguistic strings that accurately map a portion of reality. Reality is the collection of things and processes that actually exist and interactive with one another. If any of the world's religions can identify an aspect of reality that can be demonstrated to exist, then that religion has uncovered truth.
Notice also that religion and science use unrelated methods for deciding what is true, only one of which is valid in my estimation. I have no confidence in the output of any method that relies on faith, by which I mean religious type faith, or unjustified belief. Faith can't be a path to truth, since any idea or its polar opposite can be believed by faith even when the ideas are mutually exclusive, and at most only one can be true. This is the method that has generated so many contradictory religions, each claiming to have the truth. That's probably what you meant by religious truth, but I don't use that word to describe claims derived in that matter for reasons just given.
When one uses reason properly applied to all of the relevant evidence, one comes up with things like the periodic table of the elements. We have only one of them. You can call that scientific truth, but it's just truth to me.
Perhaps the only real truth is personal truth - the universe according to the individual observing it. After all, it is this truth alone which truly guides us.
That is the individual's belief set, but it is not necessarily all true. There is a place for subjective truth, but what makes it truth is that it is reproducibly observable to the individual. If I have discovered that I like coffee better than tea or that wool makes me itch, those are reproducible observations, but observable only to me. That's what I would mean by a personal or subjective truth.
Simply declaring something is true because you want it to be or it pleases you to think that it might be does not rise to the level of what I would call truth. That's more like hope which has been allowed to become belief, hope and belief being different things.
I think that we tend to get bogged down when using the word truth. People start looking for eternal principles that transcend experience. The refer to absolute truths and constant truths. I find none of that helpful.
Instead, I prefer what is sometimes empirical adequacy. If an idea works, keep it. If it doesn't modify it so that it does when possible, and toss it out when not. I happen to live five blocks north and three blocks east of the pier. We can call that a true statement if it turns out that walking three blocks west and five blocks south takes me to the pier, but what really matters is that the idea is useful for a particular purpose. It accounts for prior experience and can be used to control outcomes in the future in a way that wrong directions cannot.
If somebody wants to get into an arcane, sophistic argument about that not being a universal truth for whatever reason, I would lose interest.
