Bear with me here, as I'm just a dumb cop and not a scholar of philosophy, but by "Foucaultian" you are referencing power relationships? That the politicians campaigning on "family values" are doing so in order to command obedience and respect from voters, or rather to order and classify their tribe, or both? Sorry if I sound dense but this definitely isn't my area of expertise and some clarification would be appreciated just for my own education.
It's pointless jargon which displays only what a pretentious twat I am. Nothing dense about what you're saying, and I actually have a tremendous amount of respect for being willing to
appear dense. A lot less for term droppers... My bad here.
That being said, part of Foucaultian discourse is what I'm talking about - and while it's not about power relations per say, it's definitely part of a larger discussion about power relations.
The element of Foucaultian discourse I'm talking about is related to the formation of concepts underlying statements. Let's take a statement like "I have strong family values" as uttered by a nameless American politician. What does that mean? Well, it references a set of concepts and ideas which, in the terms of the discussion, it is the expectation that the audience he is speaking to will hold. Let's call these "American family values" from here on out.
Now, I think we can agree that American family values aren't universal family values. So, where did this concept of American family values come from?
Did they come from the American people? Yes they did - it's a shared set of beliefs that the (hypothetical) American people have adopted and hold and we can sum up and say "American family values" - a statement - and have people have a general idea of what we're talking about. How did they originate as distinct from, say, Confucian family values? Well, some Americans started identifying them as their family values creating a distinct subset of family values. At this point, consider how this concept was produced - it didn't come from on high or some such. It came from a bunch of people acting in a certain way and entering into a discourse with others, describing what American family values were. After people discussed the idea there was give and take, negotiation, clarification, etc etc, and a corpus of American family values was established. The process of discourse created this recognizable concept of "American family values" that we all just sort of get when an American politician says "I'm a family man" - and we know he's not talking about child marriage, he's talking about white picket fences and Apple pie.
Consider, then, being an individual in American society. You adopt American family values because you're an American - you enter the discourse, negotiating it, partaking in it, constituting it, creating it. When you describe American family values in this discourse, you say "American family values are thus" - and, in describing it, you also create it. Consider above, the process by which the statement of values were created - the discourse that both describes the thing in question, while creating it. The description is the creation.
This is Foucaultian discourse - that American family values is a discursive process, people in a discussion about American family values are. What we often miss as we talk about a discursive subject - say, American family values - is that when we describe American family values, we also create - or take part in the process of creation - American family values. The discussion of the thing isn't solely describing some existing part of the world around us - it is the action by which that element is created. The whole point is - in describing something like "American family values" we essentially create it, as it functions in society. We enforce the value by declaring it thus - and we change the nature of American family values by renegotiating them through discourse and then describing them with discourse. We aren't simply the conduits of the idea - we are its constant creators.
Edit: In the case of the "defining the tribe", the Tribe just doesn't exist on its own. Why I described it as Foucaultian is that in describing American family values as part of the "American tribe" I am not just describing the tribe - I am creating the tribe. It's not like the tribe is just some monolithic idea floating there in space, whatever people say. The tribe is created (active, continuing process) every time an American politician say "I'm a good family man" and a bunch of Americans say "Yep, that's what he is, that's what a family man is" - thus describing their communal identity, the tribe, and in doing so, creating it. To point out the creative power of the discourse though, consider when someone says "Wait - he says he's a good family man, but he doesn't want to let his child have a relationship with a person of the same sex - a good family man wouldn't do that!" - and the discursive process has now described "American family man" as having a different quality than the politician said, and the definition changes, along with the tribe. The discourse, in describing the "American family man" and his qualities, also creates the concept, and the unifying axis of the tribe.
