This is the first in a planned series of posts discussing different ways of pursuing philosophical understanding.
I am the sort of person who can be very good at finding my way around a place, while having almost no ability to translate that capacity into a realistic map of the place that I am able to find my way around.
This place could be a building, a neighborhood, a city, or a more distant set of locations that are connected by major roads. In each case what allows me to get around is the knowledge of what I can do at various landmarks that will take me from one location to another: for example, turn left at the Exxon station to get to the supermarket; walk past the bathrooms and then up the stairs to the right to reach the department office; take the interstate south to exit 53A, then follow the highway over the bridge and take the first left to get to the beach.
My mastery of these landmark-based strategies means that sometimes I am able to give good directions concerning how to get from here to there in places that I know my way around, though doing this requires me to simulate in my imagination what the next relevant landmark will be after taking a given step—and this sort of remembering is something else that I am not always good at doing. Still, when I do manage to remember, or am reminded of, a given landmark along my memorized route, then what I remember is something I already knew: for example, that the road out of the neighborhood goes past an Exxon station, at which one needs to turn left to get to the supermarket.
With maps, things are different. Even if I am extremely adept at getting around a place, often I will have had no idea that the place I am able to get around has the layout that a map displays it as having: no idea, that is, that the locations I know how to get between are located with respect to one another in the ways that the map displays. In knowing how to find my way around, all I knew was what to do, upon seeing a certain landmark, in order to continue on the way to a given place. And I knew all of this very well without knowing much of anything about the spatial structure of the place I was able to navigate, or the spatial relationships between the landmarks I could find my way between.
Based on conversations with other people about these matters, my sense is that I may be a sort of person who is peculiarly bad at aligning my knowledge of how to get around a place with a representation of that place in the form of a map—though there is some experimental evidence suggesting that landmark-based navigation is the default human strategy for getting around an environment. My present interest, however, is not in these questions, but in a wider phenomenon that this is only a single example of, and which I believe provides a common impetus for philosophical inquiry.
