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.

Deception
Chapter 5

Suggestive or Misleading Questions

Previous: Chapter 4, Implication Rules

Recall that one question for the one-way rule

When Aunt Jane visits her nephew Tom's home, Tom goes out to play.

asked what could be said for certain about Aunt Jane when Tom goes out to play? The answer is nothing. But the wording in this question hinted or suggested that a little bit more could be said for certain about Aunt Jane. The question was slightly misleading. A less misleading question would be what, if anything, can be said for certain. You have to be aware of misleading questions. The topic of suggestive and misleading questions is discussed next. 

Are you trusting? Are you willing to politely accept everything I or someone else says or suggests without question? The phrase what can you say for sure in the above question makes you expect something could be said for sure, not nothing. You have to watch for misleading and suggestive questions in and outside of this book.

When someone tries to convince you with a suggestive chain of reasoning, you need to recognize the weak and strong links in that chain. Then you can decide for yourself whether or not to accept the suggestions or conclusions obtained. Faulty logic may hide some deliberate deception or some reparable chains of reason. In particular, you may see where the chain fails and is broken, or where the chain can be strengthened or repaired. In our thoughts, we need to identify or keep track of what is certain, what is almost sure, what is guessed, what is probable, and what is only suggested.

The next example is far-fetched in most worldly locations, but it illustrates a situation that you need to recognize. Suppose I asked how long have you been beating your elephant? This question suggests you own a mistreated elephant. A gullible, too trusting, person overhearing this question could believe (assume) you own an elephant. A gullible person overhearing the question could believe this unless you say the question is absurd because you don't own an elephant.

We all are slightly gullible. It is a matter of politeness not to challenge a speaker. On hearing a question, we like (or tend) to think each question posed is correct, honest and not misleading. But we need to continually watch for questions that are not realistic, especially if the speaker does allow us to challenge them. Their words may force upon us unchallenged assumptions or suggestions. Suggestive questions need to be recognized – if not stopped. They need to be challenged and corrected to prevent the reasoning from continuing in an absurd or deceptive direction.

A series of suggestive questions is intimidating and forceful. When the suggestions in them remain unchallenged, you may find yourself at the end of a long chain of suggestive reasoning, agreeing to or not challenging some repugnant ideas. So watch for misleading questions. The questions and possibly the speaker are false. Step by step, or question by question, such false reasoning needs to be exposed. The exposure could start with the very first question, and then the next, and the next, and so on.

When a speaker, in posing and answering suggestive questions, leads you to false or repugnant conclusions, such a speaker has lied and mislead you. Your intelligence has been deliberately or accidentally insulted. The speaker, a possible villain, has taken advantage of your politeness or silence. Faulty reason or lies may be hidden in suggestive questions.

+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.
