Clarity of your knowledge

To what extent can we, humans, understand what we know is “true” and our rationality? Most of the people, if not all, believes in a “truth” that can be proven either through scientific evidence, facts, experience, and things that they can see happening. But how about the things that we cannot see or have a good understanding or the things that science cannot get a full grasp of? Is this the limit of our rationality? Like the idea of a higher being or “God” of creation. Descartes, in his Meditations, discussed the clarity of one’s understanding about their knowledge of “God,” specifically a phrase from the Meditation, “the existence of God may be proved by natural reasons, but also that it may be inferred from the Holy Scriptures [such as the holy bible], that knowledge about Him is much clearer than that which we have of many created things, and, as a matter of fact, is easy to acquire…” As Descartes discussed this phrase, he also mentioned the Wisdom of Solomon, chapter xiii, on how it supports his claim about one’s clarity of knowledge about god.

To me, this is a very intriguing matter, which applies to the people around us today. They have some sort of understanding and knowledge about “god” or a higher being that is easy for them to understand even though they are not religious or anything of the like. For example, I grew up in a Catholic family, which pretty much shaped my own beliefs so my understanding about god was already clear to me. However, how about the people who did not grew up in some sort of religion but have an understanding of what god is? By understanding I mean an interpretation of what god is. Similarly, to the people who wrote the bible and Holy Scriptures, how did they gain that knowledge about god and how is it “easy” for them to understand that matter, as if it is a natural knowledge to them?

I, myself, is in the field of science but I also have my own religious beliefs. Trying to coexist these two subjects is almost impossible, but it can be possible. It is like how Descartes explained the Cartesian split, the body and the mind are two different entities but they interact, it very hard to get a grasp and understand but it is a step towards explaining and putting it into words so people will have a sense of what is going on and can provide that evidence, hence people will believe in it.
