Guys, let's face it, we need to be open-minded, because the world is such. We live on a more or less round lump of matter we call Earth. We know there are a few more lumps, we give them names too, but we have no idea how big the cosmos is entire, and how long it may have lasted, somewhere far away.

We are as butterflies new in a garden. On the side of simple facts, our humanity's like we could hop a few flowers, but that would be about it. Still, we don't get to sit all day to think what we might not know. It would be boring, soon.

Knowing all about everything is not necessary, to have something interesting going on. 

When we begin to learn language, we are aware there are great many words and language patterns. We do not need to know them all, to begin and have interesting activities. 

More, even if we get to be real good at language, we don't get to know all and everything. Nobody does.

Nobody could give the exact number of irregular verbs. Some people would use 60, and some about 80 of those, and some people would change their minds.

Nobody could tell beforehand what other people are going to say, or even myself, I can't tell what I would say in some new or unpredicted context.

Still, language has some regularities and a good book is always an interesting book. 

We can use the lemniscate to symbolize what is indefinite in language.

For what is regular, we come up with something logical.

Our logical thing will be finite. Language will remain non-finite. This is how we humans have always been: we come up with finite things to manage matters we do not or cannot set bounds to.

The infinity symbol comes from ancient Greece. Earliest known records point to Anaximander of Miletus, who called the symbol the apeiron. 

For language, we do not use the plus or minus symbols with the indefinite. Language and math are completely different, and "computer language" is a moniker for mathematical codes.

The codes use digital figures, and there's no way to tell that a letter of the alphabet, for example A or B, is value 100 or 1000. You could be only ascribing those digits to alphabets. 

Feel welcome to our logic, our gumption set: we don't think what we don't know; we think what we can establish, to rely on it whatever the context.
