When we say "right" or "true" we can sometimes mean something factual (it rained yesterday), or something moral (it's wrong to murder), but other times we are talking about the right strategy, or the right mental model.

I like the humility (is that the right word?) in your description of this. But when people say "my truth" and "your truth" I think sometimes they are allowing themselves to be content with a local minima (philosophically) because it feels good to them rather than seeking the truth in a more universal sense. Like your example of gravity, there are layers or contexts to truth where a mental model works within boundaries, but needs to expand when more contexts are considered.

Are we, as humans, seeking a good-enough mental model and retreating to a context where that model bears fruit, or are we reaching for greater understanding of the universe, and staying "on the road" toward the truth as much as we are able to?
