Axis Praxis on the importance 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.
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.
