critical thinking is good, but there is also a spiritual or moral component to believing a religion.
Critical thinking is a prescribed or constrained path based in the proper application of reason to evidence. The empiricist claims that this is the only path to truth by which he means demonstrably correct ideas about reality - ideas that help one predict outcomes. This way of thinking about truth is called the correspondence theory of truth, and underlies empiricism. All ideas that can be called correct are confirmed to be that by this method.
Other methods of arriving at beliefs do not produce truth. Ideas arrived at by other ways of "knowing" can only be believed by faith. Whatever you mean by a spiritual or moral component to belief must fit in this latter category - faith. Faith is not a path to truth. That should be obvious. A path to truth is what critical analysis provides. Its sound conclusions are invariably useful in navigating reality. Faith isn't really a path at all, as it is 100% unconstrained and untethered to reality. By this method, any incorrect idea can be believed to be correct. And that is the "path" to religious belief.
"Truth" has no meaning to me if divorced from sensory experience or making decisions. The evolutionary value of belief itself resides in its ability to inform decisions and drive actions, which lead to events in the external world, which in turn lead to objective consequences evident to the senses. Take away any of these elements and "truth" immediately loses all relevance. The ultimate measure of a true or false proposition lies in its capacity to produce expected results.
If an idea is true or correct, it can be used in the real world to generate predictable consequences, and different ones if that idea turned out to be false. In other words, the ultimate measure of a true proposition is its capacity to successfully inform decisions under the expectation of desirable consequences. By this method, one accumulates demonstrably correct ideas - one's fund of knowledge - and generates a mental map of reality that corresponds with the features of reality the way a literal map corresponds to actual geographic features one might encounter. If your map is wrong, you won't reach your desired location, and the only way to have a correct map is to survey the landscape it intends to map.
If this is not one's definition of truth, then whatever it is he is calling truth has no value navigating reality. One's religious beliefs may comfort him, but to the extent that faith-based beliefs inform his decisions, they range from useless to harmful. If you believe in angels in heaven, then you hold an idea with no practical value. If you believe they protect you when driving and drink intoxicated for that reason - that is, if this belief actually informs a decision - it can lead to harm.
critical thinking philosophers have always disagreed using reason.
Reason is only useful if applied properly to true premises and evidence. This is how sound conclusions are formed.
Why can't critical thinking go hand in hand with believing a religion? If one used critical thinking to arrive at that destination I don't know why not.
One cannot arrive at a god belief using critical thinking. There is no sound argument that ends, "therefore God." One must inject faith into the process to do that, which immediately makes it something else.
Also, one doesn't just try hard and think critically. It is an acquired skill, and in my experience, one rarely acquired outside of an academic institution. It's like doing integral calculus. You don't do it by trying hard. There is a method that must be learned, and NOBODY who hasn't studied the subject can do it. NOBODY. With all due respect, your thinking is often fallacious. Many have commented on it, but I doubt that you believe them, since you have no way to judge if they are correct or not. Nevertheless, you frequently violate the rules of critical thinking, yet consider it valid critical thought.
I know this sounds elitist to you, but don't you have training in naturopathic remedies - or maybe it's homeopathic? Mine is in medicine, or what some call allopathic medicine. Either of us can recognize when others get it wrong, because we have specialized training. It is not elitism to reject the contrary opinions of those less well trained that we can see are incorrect. Going through the pandemic was an eye-opener regarding how many people think they understand medical principles but don't. And such people routinely reject correction from those who DO have that specialized training, mistakenly assuming that their thinking is just as well informed.
