 Logic chapters 1 to 5  re- appear not in sequence, as is or longer,  in  Volume 1A,  Pattern Based Reason, Bon Appetite.

Logic Mastery
 Amazing, Amusing, Amorous,  Delicious, Delightful, Edifying, Strengthening Elixir. 
It eases work & learning difficulties Makes the hard easier. Opens eyes. Leads to greater precision.
in reading and
writing

Logic mastery makes the hard, easier. Logic mastery  leads to better, stronger and richer comprehension.  Logic mastery  improves reading and writing.  Logic mastery ease learning difficulties.  Logic mastery gives a headstart.  In sum, logic mastery  will develops critical thinking, improve reading and writing, and give a firmer base for work and studies at many levels. Good luck.


After logic  (a) continue reading Three Skills for Algebra, chapters 8 to 14  and do so alongside site area on solving liinear Equations ; or (b) see this calculus starter lesson and Volume 3, Why Slopes  & More Math, chapters 2 to 6;

What may be learnt and when depends on how skills and concepts are developed. Making the hard easier and clearer will allow earlier & richer development of skills and concepts.

Accidental Patterns
Chapter 11

Previous: Chapter 10,  Where does Responsibility begin or end? Who is to blame?

What do we mean, when we say you have caused something to occur? In life we may see a pattern that whenever a first situation occurs, so does a second. The pattern could hold true accidentally. There may be no relationship between the two situations or events. Alternatively, there might be some relationship. We need in a sense to measure this relationship. We need to measure how much one event forces, pushes or contributes to the occurrence of another event. This measurement signals to what extent the first event is a cause or is the cause of the second. Observation by itself is suggestive but not conclusive. Examples to support this view follow.

Suppose, for instance, every morning I leave my home (the first event) before you leave yours (the second event). This pattern can be seen for ten years or ad nauseum. My leaving home early does not force you to do so. While the pattern holds, we see each time the first situation occurs, so does the second. We have here a one-way implication rule which has not been disobeyed.

My leaving home each morning before you does not force you to rise as well. Our motives are independent. The implication rule or pattern we see has just been accidentally followed. There is no guarantee that this accident will repeat itself forever. One of us could change habits. You might stop going to work after me.

On the other hand, suppose I was in the habit of visiting you each morning to invite you to walk to work. Here my habit is linked to yours. The rule if I leave early, then so do you may hold. This rule is not enforced. It is voluntarily followed and not disobeyed. I am not the sole cause of your getting up or leaving home.

Finally, suppose we live in the same house. Further suppose I woke you up each morning, with the threat of no breakfast if you did not get up. Then I could be a cause of your getting up each morning. The pattern every time I get up you get up would not be disobeyed. A pattern or rule can be accidentally, voluntarily or deliberately obeyed when we deal with human behavior.

+Proof by Absurdity alias proof by contradiction
+How the demand for consistency supports the law of the excluded middle

There is a difference between
knowing how to spend money,
and having money to spend.

There is likewise a difference
between mastering a skill
and having meeting a situation in which it applies.
