LOGIC
So what is Logic?
Logic is a system of reasoning, it is the art of applying reasoning to the structure and content, the method of deduction.
In my humble opinion the grandfather of the modern puzzle would have to be none other than Charles Lutwidge Dodgson, ( who you might know better as Lewis Carroll , author of 'Alice In Wonderland ' ). In his book 'The Game of Logic' Carroll introduced a game to solve problems such as confirming the conclusion "Some greyhounds are not fat" from the statements "No fat creatures run well" and "Some greyhounds run well".
( Puzzles like this, where we are given a list of premises and asked what can be deduced from them, are known as syllogisms ).

DEDUCTIVE REASONING
One of the main principles of logic is Deductive Reasoning (reasoning from the general to the particular). It involves using given true premises to reach a conclusion that is also true. If the rules of deduction are followed, this ensures we reach an accurate conclusion.
|
An Example: 1. All people named Sally sell sea shells at the sea shore. (general) 2. My Friend's name is Sally. (particular) 3. Therefore, Sally sells shells at the sea shore. - (A conclusion from deducing the premises of the first 2 statements). |
Or, as an additional example consider : 1. All men are mortal. (general), 2. I am a man. (particular), 3. Therefore, I am mortal. ( DEDUCTION ) |
Both examples above use deduction , and these types of problems are syllogisms (again where one takes two separate conditional statements, and deduces a logical conclusion by combining the hypothesis of one statement with the conclusion of another).
To summarize , we might generalize a logical deduction as follows:
1. If , P -- > Q .
2. Q -- > R .
3 Then P -- > R .

LOGIC PUZZLES:GRIDS
|
Another form of logic puzzle, popular among puzzle enthusiasts and available in magazines dedicated to the subject, is a format in which the set-up to a scenario is given, as well as the object (for example, determine who brought what pet at a pet store , and on what day each pet was bought), some specific clues are given ("neither Mary nor Ray purchased the German Shepherd"), and then the reader fills out a matrix with the clues and attempts to deduce the solution. Common logic puzzle magazines are derivatives of the logic grid puzzle called "table puzzles" that are deduced in the same manner , but lack the grid either because a grid would be too large, or because some other visual aid is provided. For example, a map of a town might be present in lieu of a grid in a puzzle about the location of different shops. |
