In my opinion, there are three types of people:
1. If they do some good act, they will let everyone know about it
2. If they do some good act, everyone will come to know about it
3. If they do some good act, no one will know about it
Now the third point got me thinking. It is a very interesting statement from a mathematical point of view. Will we ever be able to prove that there are people of the third kind in this world?
Is there some way to know that a person is of the third kind? I think it is not possible.
Whenever you find out about a person who is of the third type, he automatically becomes a person of the second type, and ceases to be the third type! This means that you will never be able to prove the existence of the persons of the third type.
May be you will have to rely on some kind of Nonconstructive Proof to solve this problem of existence.
You can see that Schrödinger’s cat is a similar thought experiment. Both of these examples talk about some type of Observer effect.
Now if we say that there is nobody such that if he does something good, no one will know about it, it becomes a Self-fulfilling prophecy.
