Dont know if you are referring to pessimitism over optimisim or vice versa.
But my #ThirdEyeView is
i think i view it in a philosophical perspective: the entire domain of my experience of existence is restricted by my capability to inspect and to consider. i know some form of "i" exists in some form. i view and examine things, though this however by no means insinuates these things occur independently of me and my experience. i also understand my experience can be effected by certain things im not mindful of.
think on this : i could trip over something i didnt know was behind me; look at a room thru say binoculars in say the air [which changes how i view the next room], it wouldve a different experience of the room through a pair of binoculars as without.
I overstand by implication that the conscious "knowledge" currently available to :"i", might be flawed; to be in harmony between my experiences and perceived knowledge. it is therefore possible for me to "learn" to acquire altered or additional access to data/facts. i can come to believe something i didnt before or to understand it in a different way. this tells me 2 things
1.) that the magnitude of i can change to incorporate newer overstandings and
2.) That all else that can be observe or must be available to 'I' for it to be dissected and interpreted , thus it must exist at least as some of 'I' (though it still does not imply 'not I' exists in a similar manner as 'I').
An flawed I exists in a state of adjustment ; anything I discern or come to the realization exists - at least as part of I. Of this I am philosophically 'certain'.
In terms of pragmatism i accept: The only thing I pragmatically accept is the natural notion of existence; things I can and cant view yet are subject to a a group of laws and constraints, logic, the laws of existence, , mathematics etc; things that can be bent to fit these laws and to be predicted and repeatedly shown to show the flawed knowledge we have is 'reasonable' in it's capability to foresee reality even if not perfect - all of it I pragmatically embrace as 'real' elements of existence. All the while acknowledging 'I' and other cognizant things exist with correlation to being "helded" in natural containers, that each judicious notion might be similar to me in that it has flawed knowledge and does it's best to understand existence. Because of this some folk attempt to learn things and to refine understanding of existence, while others folks attempt to affirm things and to reformulate reality to fit.
