Perhaps no 4 is not an axiom.
What it is, is a set of guidelines which, if followed, enable you to
see the truth for yourself. Come to think of it, it is definitely not
an
axiom, but rather the means by which the validity of the 3 previous
"Noble Truths", which are axioms, can be demonstrated. (That
life generally is full of dissatisfaction, why that is so, and that
something can be done about it.) Sorry for my thoughtless
presentation of all 4 as axioms.
