(no subject)

Truth is not "relative" and certainly not "subjective" in the popular sense of the word. It is always, or almost always, completely determined within a thought style.
...
Truth is not a convention, but rather (1) in historical perspective, an event in the history of thought, (2) in its contemporary context, stylized thought constraint.

--- Ludwik Fleck, Genesis and development of a scientific fact.

The relationship to thought constraint sounds interesting. Also, we can probably model it as a topos of dynamical systems.
