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.

Turned against reason, this understanding behaves in the manner of ordinary common sense, giving credence to the latter’s view that truth rests on sensuous reality, that thoughts are only thoughts, that is, that only sense perception gives filling and reality to them; that reason, in so far as it abides in and for itself, generates only mental figments.

In this self-renunciation
of reason,
the concept of truth is lost,
is restricted
to the knowledge of mere
subjective truth,
of mere appearances,
of only something to which the nature of the fact
does not correspond;
knowledge has lapsed into opinion.

GWH Hegel, The Science of Logic.

Hegel was extremely successful in his project to rediscover truth and put on a solid foundation of new logic. I wonder whether something like that would be even possible in today's world. What would it take to overcome the post-truth attitude in our society?
