...sounds like most of the sciences today. Theory upon theory. Could it be that life on earth itself is one big conspiracy? Everything almost is in question and theorized.
I know what you mean. I try, and I teach my kids the same, to stick with what can be known. Our senses trick us. A lot of this life is an illusions, and I think we'd do well to know that, and not place a lot of faith in what can't be known.
You know, this idea of life as an illusion is very much in line with some of the great philosophical thinkers back in the day. Not that they discovered anything that others may not have thought as well, but men like Plato and Socrates and many others, realized that we are in a state of constant change, or flux. And, that we can not always trust what we see, hear, taste, touch or smell. This same thinking is very much alive in theology, when we consider our will and God's will. God is the same today as he was yesterday, or will be tomorrow, but we are not. God is, and we are simply "being".
The irony of man's "free will" is that he desires, by his own fallen nature, to trust in what he physically senses more so that what he does not, or can not. This is an oxymoron of the term "faith" as some might use it. The question should always be; "faith in what, and by what means". If we can't trust our senses and life is an illusions, what can we trust , how can we trust it and by what means?
So, since I can know two things, 1. that I am in constant flux and are simply "being" and 2. that God "is", I have no choice but to place my faith in that, and that alone, ultimately. Otherwise if I place my faith in what I can know physically, by my own senses, and those things are simply "being" in a state of constant change, then they are not real, and my faith is a joke. It's like cotton candy. But, if I place my faith in what "is" then my faith is not my own, but a part of what has, is, and always will be even if I can not perceive it, because I don't have to. All I have to do is apprehend it. This is not the deep end of rationalism, but the very foundation of it, of which no thinking person can escape without being fooled by an allusion (illusion) and victimized by some sort of conspiracy theory, regardless of how logical it might be.
