Metaphier and metaphrand

Jaynes described a metaphor as comprising of two parts. The metaphrand is the thing to be described or understood, and the metaphier is the more familiar thing with which it is compared. The human body is a very common metaphier; we speak of the head of a table, the foot of a mountain, the face and hands of a clock, and the mouth of a river.


Magical scientist ability

[...] metaphor is more than a classroom aid. It is a crucial element of discovery and invention. Scientists are not blessed with a magical ability to apprehend the world as a vortex of symbols and equations, as Neo appeared to do in the film The Matrix. Scientists, like everyone else, seek to cast what they see in terms of what they have already seen.


The power of metaphor

To fully appreciate the power of metaphor (and it’s more formal cousin, analogy), we must look to its oft-neglected role in science and technology. We speak of a genetic “code” or “blueprint”. We explain the structure of the atom to schoolchildren by analogy with the solar system. We think of the brain as a machine, or a computer, or a social network. These metaphors and analogies can help impart new ideas to the student and the layperson.
