"A common and useful analogy is often made with building materials. Transgenic organisms are like houses built with stone; the material was found elsewhere "in nature"
and remixed to make a house. Synthetic organisms are like houses built with plastic (or LEGO bricks); the building material did not come already formed from the "natural"
environment like stone did, but was produced elsewhere and inserted into it. I include scare quotes around "nature" and "natural" because, of course, those terms are fraught and loaded"
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.
