 One manifestation of this view is found in the cognitive science of mathematics, where it is proposed that mathematics itself, the most widely accepted means of abstraction in the human community, is largely metaphorically constructed, and thereby reflects a cognitive bias unique to humans that uses embodied prototypical processes (e.g.counting, moving along a path) that are understood by all human beings through their experiences.The conduit metaphor is a dominant class of figurative expressions used when discussing communication itself (metalanguage).
