To add is nothing. To add what is already there is less than nothing. To subtract and be left with the same is more. To subtract and be left with more is a true achievement. Reality is the final arbiter; as all our beliefs, crazy or not, must remain testable. It is equally stupid to reject a crazy testable hypothesis as it is to hold a crazy untestable hypothesis. Type-1 and Type-2 errors during rational thinking... I want to strive for empiricism in my life.
