When we watch a still set with an apple, a banana, or so for drawing a picture, each thing has outline, but if we change the angle to watch from our position relevant with objects, then outline is anytime momentary and expedient, but it could never be made as makeshift, necessarily for anybody who tries to watch at the same position and its angle to the objects, it way to be seen almost the same, of course each ones has own image, but outline shape is not so different to anybody.

Meanwhile, if we think of mind itself, that thing is seen to probably anybody so exceptional, because only it could never replaced to another one for each one. 

Loving emotion, desire to love other one as gender, or so must be physically tangible and sensation only each one has, just other ones can confirm or recognizae one person's mind as presumption with expression, behavior, attitude or so. We Just read the other one's mind in having own emotion.

Then, looking at something located or positined something and our knowing each own mind( of myself ) is completely different.
These natures' gap has characterized feature the truth that visually confirmable phenomena must be easily objective object, but mind, body sensation, or tangibility are all never be objectively confirmable, then these things depend only on informing by each one whose felt matter is on an issue at communication's context. Thereby it must be only shown with explanation, then its factual credibility depends only on our own subjective confidence, and felt content is either subjective to any of us.

Then, we can define that we all have mutually very contrustively completely different certainty. In other words, objectively confirmable things are, if it is visual or auditory phenomenon, in fact confirmable certainty and it could be publicly objective, but for example my stomach ache, or my loving emotion to somebody are never confirmable to anyone but myself, then these things must be presumable certainty, because that certainty would be confirmed only by e.g. my sweating state at my face or so only could be confirmed by the other ones but me, only I can have certain feeling.

These facts would show that eventually we all are convinced with mutual trust and descision to understand mutually specificly exceptionally only to the matters relying only on person's confession, then we all are understanding implicitly toward reality, it must be composed with society or world itself in given view by us that completely different characterized certainties of these two should never be queted by any of us so tacitly, and implicily anybody complies with that implicit regulation to world, and society, that thing must rely on language's rule.

To this extent, we all are only in epoche never to quest more than regulated things necessarily. 
Additionally, we survive the society with language as even the same word e.g., certain, with public, private, or public, personal, internally immanent and externally confirmable in having contrustive dimendioned things mixed together. In other words, we even have some question to these facts, we are bound to the commonsense that never confirmable matters must be held it back to argue about or evidence so rigrously around mutually completely different certainties, and we abstain from holding against each unconformable matters impliciltly.
