The idea that we already (in childhood, spontaneously) know everything truly-knowable, but are unconscious of the fact - and that learning is a kind of remembering and making-explicit and understanding....
That idea has a complementary aspect, which is that our spontaneous childhood beliefs and wishes have a validity, even and especially when these Bs &Ws have no correspondence with earthly reality, experience or apparent possibility.
An example is flying. I have clear memories of not just yearning to be able to fly (fly by 'levitation', without wings or propulsion - just moving through the air), of knowing what it would be like to fly, and the conviction that it was possible for me to fly... if only I could discover the 'knack'.
More profoundly, I - like most people - was apparently born into this world with the belief that it ought to be a paradise; and that any departure from paradisal conditions was a kind of violation: unjust, against the order of things.
Now, obviously there is no biological basis for human flying, nor any social basis for life as paradise; and therefore such in-built hopes and beliefs are either extraordinary yet common delusions or reality-distortions; or else they relate to a reality that is different from our own, but of which we have memory.
My assumption is that this reality is of pre-mortal spirit life - when we could indeed fly, and life was indeed paradisal. And at an unconscious, implicit, but effective level - we remember this...
We could also, as spirits, do many other things that I believed (against the evidence) was possible; such as read minds, communicate telepathically, change the world by thinking a thing, have my thoughts compelled, move things by a kind of telekinesis, and 'talk' with animals and befriend them.
(Interestingly, such beliefs also re-emerge in people with psychosis and altered states of consciousness.)
In sum, I think that we could reflect more on these childhood, and - in our culture - child-ish, counter-evidential beliefs and desires. And could regard them as destined paths to truth - things we need to become aware of, and to understand.
Note: The above is a version of the 'argument from desire' which was used often by CS Lewis, and also by JRR Tolkien - and which I personally find compelling. I refer to it and provide references in this essay.
