That makes it sound very arbitrary. It's more a case of "that's the way
it is because mathematicians have determined that is what is most
sensible and thus they say so". That determining was the culmination of
the hard thought of numerous people and you can learn the details from
history books such as Hairer & Wanner's 'Analysis by its history'.
