Polanyi, Michael. The Tacit Dimension. University of Chicago, 1966 [2009].
If you want to begin reading Michael Polanyi, and you should want that, I have good news and bad news about this book. First the good news: it is short and many of his arguments are to the point. In some ways, he clarifies arguments from Personal Knowledge. Now the bad news: it is difficult. Be prepared for that.
Before we begin, we have to define and emphasize two key terms: proximal and distal.
Proximal: the particulars
Distal: the meaning of a term or entity
His argument is straightforward: knowledge has a from-to character. In other words, we know the primary term only by relying on our awareness of it for attending to the second (Polanyi 10). The first term is proximal, or tacit. The second term is distal. The proximal term represents the particulars in knowledge. As Polanyi notes, “Our body is the ultimate instance of all our knowing” (15). Polanyi does not use the metaphor, but our body is the interface between our mind and the outside world.
Thus, we “interiorize” the knowing process. This is “to identify ourselves with the teachings in question” (17). The proximal term of tacit knowledge establishes the framework, integrating the particulars. In Polanyi’s fine phrase, we are “not looking at particulars but dwelling in them” (18).
Dealing with the problem raised by Plato’s Meno, Polanyi explores the paradoxical nature of research. How does one find a good topic to research? On one hand, it has to be original, yet on the other hand there is no guarantee it will be good. At best, we are merely guessing at a coherence before we have the particulars. Plato, by contrast, did not see that we can know things we cannot tell, at least on the tacit level.
Our body is invested in our perceptions. That is how it participates in the knowing process. The body’s (tacit) knowing expands into the world, gaining new sets of particulars (29).
There is a correspondence (in tacit knowledge) between the structure of comprehension and the structure of the comprehended entity which is its object (33-34).
Levels of Tacit Knowing
The proximal level is the foundation. The distal builds upon it, yet the proximal can never account for the range of knowledge. For instance, one’s vocabulary builds upon phonetics, yet phonetics can never limit the range of knowledge (36). The distal relies on the provincial but its operations are not explained by it. This leads to the problem of emergence. Higher levels control the boundary conditions left open by the operation of the next lower level (45). In other words, “a level can only come into existence through a process not manifest in the lower level.”
Kataphysical Knowledge
Knowledge is personal but also subject to and shaped by impersonal requirements. This might be what Thomas Torrance called “Kataphysical knowledge.” Far from an impersonal knower, the scientist is engaged in “imagination seeking discovery” (79).
Conclusion
This is necessary reading for the student of Polanyi, but most people would be better served by reading Esther Lightcap Meeks.
