Functionalism is a theory of the mind in contemporary philosophy, developed largely as an alternative to both the identity theory of mind and behaviorism. Its core idea is that mental states (beliefs, desires, being in pain, etc.) are constituted solely by their functional role – that is, they are causal relations to other mental states, sensory inputs, and behavioral outputs. (Source same as above)
FIML differs from philosophical functionalism once we get beyond the generalities. FIML treats semiotics (a most basic element of communication) as good data (if agreed upon by both partners). It then uses this data to show partners how their communicative awareness is actually functioning. Since data points are necessarily small, their function can be determined with reasonable certainty, a degree of certainty much better than that obtained through the application of an overarching theory to the same data point.
For example, if you (my partner) believe I said something based on anger or a political leaning, you have a theory about why I said what I said. If you do a FIML query and find out from me (a truthful informant) why I said what I said, you will have a small fact to replace your big theory. Very often it turns out that I (or your partner) said what they said not due to your theory but due to something else entirely.
Seeing the difference between your acquired “theoretical” theory of mind and the actual factual state of your partner’s mind—and seeing this many times—will relieve you of many mistakes in how you perceive and interact with your partner.
In time, this relief will extend to others to some extent, though in a world where only a small number of couples are doing FIML we cannot expect others to function interpersonally with the same degree of honest agility as our FIML partner.
I believe the day will come when many people do FIML or something very much like it. That will be a time when humans have even more leisure than today, when robots do most work and through their impressive skills and intelligence have unburdened us from the need for status displays or exercising mindless power over others.
Compare FIML practice to traditional forms of psycho-analysis. Instead of subjecting your inchoate mind’s vague problem(s) to a paid theorist or dispenser of pills, you will in the security of your own domicile be able to observe and analyze how and why your mind reacts and communicates as it does. You and your partner will be free to draw on what you know and understand to observe and investigate your minds as they actually function in real time.
FIML cannot do everything, but it provides great detail in an area of activity—communication—that is crucial to being human, whether you are with others or alone.
The entry on functionalism linked above is interesting and worth reading, but after the first few sentences it veers off into something that FIML is not. FIML is not a complete theory about how minds work. Rather it is a theory about how semiotics function in real time and how understanding that much better (through FIML practice) leads to better communication and a better sense of well-being overall.
An interesting benefit of FIML is you don’t have to wonder if your partner is thinking something weird about you because they will ask long before it gets weird.
FIML might also be called Dynamic Semiotic Analysis or Functional Semiotic Analysis, but I decided on FIML some time ago and believe it is a good enough name. FIML is not exactly doing meta-linguistics, but it is close enough and most people are more familiar with that term than semiotics.
A note to psychologists: You guys do great work. I am not against you. FIML is a practice designed to optimize communication and self-understanding. If you have clients that are doing more or less alright but still feel they are missing something, teach them FIML. Depending on their and your skills, you should be able to teach couples how to do it in approximately four to eight sessions.
