That definition of insantiy is worthless. Consider this: You push the button once. Nothing happens. You push it again. Nothing happens. Does that mean nothing will happen in the future? No; that all depends upon what's going on when you push the button. Perhaps nothing that _you can observe_ happens. FWIW, 'insanity' has many different definitions depending upon what kind of insanity you're talking about. There are different types of psychoses, schizophrenia, and sociopathic behavior as well.
