I found your post very stimulating and it brought a number of thoughts into my mind. Hopefully my reflection provides some value in return.
By setting the stage for our reality at such an early age it makes sense that our impressions would lead us astray fairly quickly. As you say “perception of reality at this stage is identical with reality, and perception is not thought as being part of it” and this makes me think that because reality is not letting us down for enough time to form a trust or belief in reality that we begin to take it for granted and further presume that reality is never going to let us down. The first time something unexpected happens we begin to have our reality corrupted because we can no longer believe reality entirely so we use our own faculties to form a newer version of reality.
Furthermore since truth can regularly be unforgiving, and, as individuals, we normally incline toward not so much torment but rather more joy, we essentially don’t care for our little self-deceptive universes to be resentful about such an inconsequential issue as truth. We don’t stress over the outcomes we may need to manage tomorrow; we simply need to feel great today. In any case, we just prevail with regards to deceiving ourselves when we participate in such shallow considering. Actually one must will to encounter the inconvenience regularly connected with truth if his goal is to accomplish positive, long haul outcomes.
I really like your usage of the idea that the brain is a filtering system - Another significant deterrent to a precise impression of the truth is the thing that I get a kick out of the chance to allude to as pattern confinement. In a sense the brains ability to filter is restricted to learnt patterns.
We are altogether restricted not exclusively to the planet on which we live, at the same time, allegorically, we dwell inside our own particular mental universes. It is hard to fathom thoughts and conditions we are not familiar with hearing and seeing inside the imperceptible parameters that encompass our lives. Along these lines, one of the reasons for our varying impression of truth is that we as a whole begin from our own arrangement of suspicions. This is absolutely the motivation behind why the genuine searcher of truth must figure out how to address everything and surrender appreciated thoughts, regardless of whether it implies enduring distress.
To become ones own liberator from pattern confinement requires a receptive outlook. This requires dismissal of custom and convention as a premise of certainty, and, in its place, acknowledgment of rationale and reason. To get destined for success in life requires that you figure out how to accurately see reality and have the strength to acknowledge it.
Interestingly this reminds me of a construct that I have in AI called an inceptron. An inceptron takes with it an impression of said reality, relying on no proof and afterwards the resultant is questioned as knowns(another construct) are built - being equal in theory to the assumption you mention. Just a side note.
I could not have said it better myself Meno_
You have made an interesting topic even more interesting, thank you for that.
