The subject of Reason is not one taught in modern schools. It died out on the curriculum back in Socrates days.
The almost unbearable course in Logic, sometimes found hidden under the Philosophy section of the college course list, was one of the most difficult and convoluted courses I had to sit through for the most obvious fact of there being no clear and agreed upon definition of “Logic” used throughout the ages, much less modern times.
“Thinking” is all about good ol’ fashion looking and comparing what you see to what you have seen or past answers.
There are differences and similarities to everything you observe. Only with the step of honest looking can you get answers to help you decide what to do.
When you are looking for logic in a pile of information or a seemingly confused subject the game becomes to look for the illogical. To do that, you have to define all the ways something can be illogical.
With such an unpresumptuous book cover it is, by far, the simplest and best course I have ever come across to teach young adults the concept of reason and logic.
There are consistent and easy to grasp definitions for the words. For example:
“Thinking is observing things and comparing them to what you have seen or gotten answers about before, so that you can get answers about how things are or decide what to do.”
“Sanity is the ability to recognize differences, similarities and identities. “
“Fact is something that you can show is true.”
“Opinion is a kind of idea which may or may not come from facts.”
It goes on and on with plenty of drawings, examples and directions.
If you can swing it, get yourself or your kid (s) through this book and course.
