The overlapping region of the trefoil venn diagram of what-is/how-can/why-ought (from my chapbook) forms a reuleau — a confluence of intuitions where people are most likely to feel an urgent need to establish public, objective truth.
In this objective rouleau, we feel that a matter is important, that we can and should respond to it practically, and that, in order to do so, we will need to clearly understand it — to conceptualize, speak, reason and argue about what it is, how it functions, how we can respond to it, why it is important, and so on.
This intuiting, responding, articulating, valuing activity creates the kind of densely tangled, knotted and enmeshed reflextive activity that tends to solidify our ideas (like the knitting of bone cells) and makes them not only seem true but to become socially true through being performed as true, and act-ual.
(For all you reckless flakes, I woke up from a dream last night with this thought in my head. Woo-oo-oo!)
