First, would it be a reasonable summary to say that a subjectivity is a role (say being a pedestrian) that a person can engage in? I mean, would it be a mistake to speak of subjectivities if we are not dealing with persons? — Dfpolis
I don't think this would be the right way to put it: in a strong sense, the subjectivities we inhabit are
constitutive of who we are as people: your ability to walk, as distinct from another who cannot, contributes to making you the person you are. To speak of 'roles' is a little too 'distant', as though people could swap and change roles as if costumes. Or, if we want to play etymological games, it's worth remembering that the word
persona means mask: the person
is the mask, and not some already-constituted agent standing behind it. Or, differently again, we could say that subjectivities are not roles that people engage in; rather they are roles that engage people in them.
Could you give a few examples of the implications being discussed so that we could see how this projection of human activity illuminates political philosophy and ethics? — Dfpolis
Well, a basic question might be something like: what kind of subjectivity does this particular social and political arrangement foster? Which would translate to something like: what kind of capacities - opportunities, risks, limitations, powers - does this particular socio-political arrangement enable or disable? If we take the street-walker as a hopefully uncontentious example, one can track the history of how roads, which were initially made for people, gradually became car-orientated; this is actually a super interesting history, one not often told: of how, when cars started to occupy streets, it was considered something of a travesty -
(Except from a Smithsonian article on this: "Things changed dramatically in 1908 when Henry Ford released the first Model T. Suddenly a car was affordable, and a fast one, too: The Model T could zoom up to 45 miles an hour. Middle-class families scooped them up, mostly in cities, and as they began to race through the streets, they ran headlong into pedestrians—with lethal results. By 1925, auto accidents accounted for two-thirds of the entire death toll in cities with populations over 25,000. An outcry arose, aimed squarely at drivers. The public regarded them as murderers. Walking in the streets? That was normal. Driving? Now that was aberrant—a crazy new form of selfish behavior.
“Nation Roused Against Motor Killings” read the headline of a typical New York Times story, decrying “the homicidal orgy of the motor car.”
'When Pedestrians Rules the Streets)
This change ramifies on the subjectivity of the street-walker: the road, no longer made for the walker, becomes engaged with in a very different way: one's walking is regulated like never before: traffic lights, pedestrian crossings, the shrinking of thoroughfares available for mingling. This has massive impacts on the ways cities are structured, which have effects that themselves ramify on the flows of capital, on distributions of class, power, educational opportunities, and so on (see, for example, the recent efforts of multiple cities around the world to keep cars out of the city centre in order to have more public space:
eg1,
eg2). These efforts can have effects on, as is well known, the quality of a democracy (
eg1,
eg2), or else the quality of a city's environment, and so on.
These efforts and debates can all be seen as - although they are not simply reducible to - revolving around the question of what kind of subjectivity ought to be offered to the street-walker. What kind of opportunities should people have to claim the streets as their own, without cars everywhere? And what kind of ramifications do these considerations have on environments? Democracies? Urban planning? Populational well-being? These are all questions bound up in political and ethical considerations. What kind of society do we want? Who or what do we valorize on the streets? What scarifies and compromises do we make to ensure safety, efficient transport, and happiness? I'm not saying that all these questions are themselves reducible to questions of subjectivity: only that taking into account subjectivities offers another perceptive on things, something else to take into account: by making a certain change in how we approach our streets, do we diminish or enhance the subjectivity of the street-walker? Would this change be a good one? Balanced against what other considerations?
Anyway, that's just one example, hardly exhaustive, but hopefully illustrative.
