moral barometer
"A moral barometer is like a diploma or letter of reference. When you apply for a job, credit line, condo, etc, the manager (or whomever) is going to want to see your credentials and references. What's more, s/he might insist that the diploma/reference had been issued by someone/entity of high repute and veracity. So, when an atheist says "I have a moral compass" Our next question becomes: "And from whom were these moral standards established?"
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
