If you get a counterfeit bill from the bank and get caught passing it---you are stuck with it?
I was surprised to find out when I was in college...even the post office wouldn't let me return damaged stamps!
Even the mother of theology is philosophy--it all--science begins and ends in your mind--soul--self!
You shouldn't pass bogus bills--thoughts.
If you want to be in science--reality...you have to know the difference between possibility and probability!
That would be a good start!
