Many years ago I was browsing in a used book store and came across “Human Evolution Coloring Bookâ€. I bought the book because I had never studied such matters and I thought this might be as good a beginning as any. Basically the book encouraged the reader to use colored pencils as a means to trace the anatomical evidence for evolution.
Years later I began to wonder about how the faculty of reason developed through evolution. Surely one should be able to find the evidence of a budding faculty of reason being formed just as gill slits or fins (I forget which) can be identified as a source as evolution modified “old†structures to create “new†ones–the human hand.
Last year I discovered “Philosophy in the Flesh†by Lakoff and Johnson. Lakoff is a Professor of Linguistics and Johnson is a Professor of Philosophy. The authors of this book write a clear and detailed explanation of metaphor theory. This theory, I think, will become the first paradigm for Cognitive Science. This is truly a revolutionary theory. If it does become a first paradigm for cognitive science it will change many of our fundamental concepts of human nature.
Metaphor theory, constructed from hypothesis verified by empirical data, has three major empirical findings. 1) The mind is inherently embodied. 2) Thought is mostly unconscious. 3) Abstract concepts are largely metaphorical.
There is adequate empirical evidence to support the following:
- We have neural networks that control our movement and perception in space.
- These networks contain neural groupings that are capable of accomplishing inference and conception.
- All of these motor-sensory networks are fixed in brain spaces and are part of our legacy at birth.
- We unconsciously create and fill spaces in the brain when we conceive beliefs (the social sciences seem to use belief to represent ideas, thoughts, beliefs, etc. when we do not wish to argue over the word used).
- Space A can unconsciously connect with space B and ‘map’ neural ‘logic’ between spaces.
All creatures categorize; friend/enemy, eat/not eat, etc. The categories we form are part of our experience. Formation and use of categories is the essence of being for all creatures. Concepts are neural structures that occupy brain spaces and allow us to do things with categories. Often we envision categories using a space metaphor. The space metaphor is a container. A great deal of the functioning of any creature uses the container prototype. We experience the world unconsciously using the container prototype and thus have a great deal of accumulated ‘wisdom’ about such matters and it is this ‘wisdom’ that becomes our “primary metaphorsâ€
“An embodied concept is a neural structure that is actually part of, or makes use of, the sensorimotor system of our brains. Much of conceptual inference is, therefore, sensorimotor inference.â€
All creatures have, by way of their sensorimotor neural network, some capacity to conceive and to infer.
When metaphor theory speaks of “metaphor†it is generally speaking of a brain phenomena wherein the “reasoning†and “logic†content of space A is unconsciously mapped onto space B such that the concept in B has attached to it the inference and logic patterns of the space A. When space A happens to be a primary experience then A is called a primary metaphor. Space A can pass to B and B to C etc. You can see that all concepts are thus ‘grounded’ in experience.
A good essay of the theory is contained at ac.wwu.edu/~market/semiotic/lkof_met.html
I would be interested in reading the impression that this theory has had in philosophy circles. If those who are acquainted would give me an idea of your judgement regarding this theory I would appreciate it. I know enough about this theory to understand it but I am not capable enough to defend the theory.
