Some Baiscs
0th: you have to have meaning and value, which only a True Faith can provide.
1st: for every text/words/sentences, be careful to distinguish between facts and opinions; and for every text/words/sentences, be aware of its denotation and connotation and their functions.
2nd:self recursion is a very interesting and permeated phenomena than a logic paradox like the “dictionary paradox”.
Examples: there is a book titled “What money can’t buy”, but you first need money to buy this book if you want to know it. I often want to use Google to help me understand how to get around on the internet and I certainly used Google to know how to solve a particular problem when I was installing an Operating System for my computer, but I realized that you first need a computer and internet to know ‘how-to’s of computer and internet; people developed software to teach “how to develop software”.
Extra point if you get it: the “chicken and egg” question is meaningless if you are sure both of them are end up on your dinner table anyway.
