Reality is Both Meaningful and Meaningless

Must say that neither 1, nor 2 are obvious. Actually, the meaning is merely dim and vague.

Let's say you understand a certain concept, so you wanna know where or how did you get that concept to be understood? It might be presented in your head since your birth (Socrates, Plato), or taken from the outer reality (Locke), or this is derived both from you and reality as some kind of the merge or the fusion (Abelard). In any case there are situations for which no certain concepts are needed. Let's say you meet a girl, and you don't speak her a word, while she understood you and did what you wanted she did; or it might be that the concept lighted in your head, and you don't even realize how that was happened. In that latter case any rational explanations are faded or gloomed. But doesn't it mean you don't understand something? - No, it does not.

And this is not about it. The most difficult riddle and along with it the most often phenomenon that happens almost everyday is that people can understand each other telling a lie, or telling nonsense, or kinda. Let's say a girlfriend asked her boyfriend to came her that night, while she meant not that, she supposed her boyfriend ignored her; the boyfriend got that information being twisted (let's say that was another girl who loved that guy, and she wanted to break the couple), but as soon as he got that information wrongly he ignored her ask, however the result will the same as the girlfriend expected. So, we don't even know anything for certain as soon as the information we're using is some kind of a mediator who delivers it from us to someone else. And until we are necessary sure about that mediator and all the path - we never know about the meaning.

What you've described is not meaning, but reference. The meaning is more complex, it might have connotations. Let's say there's a phrase "what a donkey". It might be about as a person who's lazy, or about an indeed good donkey. Here's the reference either to the actual donkey, or to the abstract emptiness.

If A means B, and B means C, C means D - this is a dead circle. There's no way out. 

google is trash; 

might be that your meaning of meaning was not the same as mine. Anyway, a means b, b means c, and so on doesn't work anyway.

I don't know what do you mean by what you say about the forum. You don't like it or something? By the way, here's the explanation to this paradox of the infinite regress: there must be a simplest or the elementary thing that must be accepted or assumed by many. Otherwise, people would never stop referring to something else.
