“When it rains, then the street is wet.”
This statement is true under ordinary atmospheric conditions on earth. The statement itself is an implication. An implication is indicated by the word HENCE or the combination “IF … THEN” or “WHEN … THEN”, but also by the words INDEED … or BECAUSE …, and there are others.
Any implication has only one direction.
The implication is a one directional connection between two elements. In this case: “It rains” => “street is wet” making a combined statement.
When we reverse the direction between the two elements, our new statement is not true any more:
“If the street is wet” then this could be because a water pipe broke, or because the local government is cleaning, or because 5000 cows went through town, and decided all together to ease themselves on the street. So we cannot conclude that it rains just by seeing the street being wet.
However, if we first inverse the elements, and secondly reverse the direction, we end up with a new truth:
“The street is not wet” => “It does not rain”
As simple as what I state here above – one of the building blocks of philosophy, and logic – this is not understood by most people.
The main problem is our language.
We say things like “if a+b=10 then b+a=10”
In this statement the direction can be reversed, and then we end up with a double arrow and we should have said “saying that a+b=10 is the same as saying that b+a=10” or
“a+b=10” <=> “b+a=10”
So we have a problem in our language, resulting often in bad logic.
Those believing in Karma or its Western version, “The Law of Attraction” should think twice and find out whether there is more than one reason why people are in their life where they are in this life. And if there are indeed multiple possibilities – and I’m very sure there are – then they should think about 5000 cows in the street and not reverse the arrow hence pointing towards an inaccessible past.
