Truth and how not to find it

It's well known fact that if we believe that we will do something, be something; there is a good possibility that it will happen. It has something to do with if you are looking to notice something you will notice it. Like noticing how many there of the same type of car as the new car you are driving.
Well the opposite is just as true. If you have made up your mind that something is NOT true, then you sure NOT to find it.
Like the riddle, What is black and white yet red all over?
Well if you read the riddle the spelling would give it away, so I wrote 'read' as 'red'.
A newspaper is black and white yet read all over. If you stick to the obvious that nothing can be black and white yet red all over, then you will not see the secret of the riddle.
African philosophy has the ability to hold two apparently contradictory concepts in mind without trying to resolve the apparent conflict, because it maintains that this is a common thing and may be easily resolved when additional information comes to hand or the concepts may be seen in a different light.
Keeping the possibility for resolution with an open mind means that the solution will be seen when it comes along. Being closed to it makes us blind to the solution when it appears.
Likewise truth may be hidden to the one who has decided it is not true. Don't make negative decisions on truth in a hurry. We may miss it.
