Logic Truths and Language Statements

Concepts, statements, and arguments are just ordinary words and statements combined according to a prior system. In this sense, logic itself is merely ordinary grammar and language. I can't come to know or understand anything without having some kind of idea about it. Hence I can't know anything without naming it and using words to describe and discuss it.

Concepts by themselves are not knowledge. Concepts have to be combined in statements. Words and word combinations by themselves just don't make complete sense. Words have to be put into some kind of statement in a structure first, to make a complete thought or become capable of being true or false. In other words, logic is in a sense just the grammar of thought. And logic is the knowledge tool in the same way that language is.

Both language and logic are required to communicate, achieve, obtain, and have knowledge.

I take my use of language for granted, usually not even thinking about it or having any concern with perfecting my use of it. And I treat logic the same way, which is part of why I'm likely to think of mind tools as artificially contrived instruments of scientists instead of basic natural knowledge tools such as concepts, statements, and arguments.

Concepts, statements, and arguments I also take for granted and hardly ever try to understand or master them.

But logic and language are not the same thing. The English word "house" is different from the German "haus", and "haus" is different from the French "maison". Yet all three have the same core meaning, different as words, but all conveying the same basic idea or concept. So there's some difference between linguistic entities called words, and the ideas I intend to convey using those words.

And there's a similar difference between statements and truths:

  • He laid the book on the table.
  • Er hat das Buch auf dem Tiseh gelegt.

These two statements have different grammatical sructures, but say mostly the same common or basic thing. Both statements are designed to express the same basic truth. Given multiple languages, there are a large number of ways to express this truth using statements with different syntactic structures. But unlike grammar and linguistics, logic is about the inferential structures of intended truth, not directly about statements and their linguistic and grammatical structures.

So there are thought rules and active thinking, logical entities and the language used to communicate thoughts about logical entities.
