Science Is Trial And Error

Now, that there are unscientific things is not my grief.  That’s a nice word.  I mean, that is not what I am worrying about, that there are unscientific things.  That something is unscientific is not bad; there is nothing the matter with it.  It is just unscientific.  And scientific is limited, of course, to those things that we can tell about by trial and error.
