As a metaphor, a touchstone refers to any physical or intellectual measure by which the validity or merit of a concept can be tested. It is similar in use to an acid test, litmus test in politics, or, from a negative perspective, a shibboleth where the criterion is considered by some to be out-of-date. Wikipedia
