Are there formal ways (outside of mathematics) in which axioms are chosen? Can you give guidelines in constructing axioms? Must axioms base themselves in sensory awareness?

Axioms are the foundation of a theory, that from which all its claims are derived. What then grounds or justifies the axioms themselves? In practice, axioms are justified in large part by their implications. This may sound circular, but isn't on reflection. As we start theorizing in some particular domain of inquiry, we already have firm ideas about some truths and falsities, and we want to formulate our axioms so that they confirm these antecedent commitments. This approach is captured by the term axiomatization . We are to axiomatize our antecedent commitments, that is, we are to formulate a small set of axioms from which we can elegantly derive the much larger and messier set of propositions we hold true antecedently (including negations of propositions we hold false antecedently). Of course, such an axiomatization is successful only if the set of chosen axioms does not permit derivation of a contradiction. Somewhat paradoxically, axioms are then justified not by appeal to something...
