Is there a common set of universal truths?

What it is, I cannot say. As I have previously stated, this is vast, complex, and abstract, something that is difficult to put into words, let alone effectively communicate with others.
One must either base their beliefs in this matter on pre-existing ideas or come up with their own perspective.
So I shall simply settle for a synthesis.
So you seem to affirm that there definitely is some non-corporeal but essential quality to reality. A layer of emotionally significant ideas existing in individual thought alone. But these ideas are impossible to gather information on, thus leaving the person incapable of sharing any objectively valid attributes of them with others. The best that can be relayed are simply suggestions as to possible courses of potential interaction. If this is the case how do you ever hope to get synthesis on this?
Where ever you go, there you are. Make the best of it.
