As far as people are considered, the only knowable truth is the stuff which is established by the context of our existence.
For example, I know it's true that gravity makes stuff fall. In this context, truth is defined by a body of memories, and of the ability to currently validate it by picking up a rock. Is the rock "really" there? Yes, as an experience. No, as I experience it. Maybe not, as an object with an existence independent of my experience of it.
Take a hammer. In the context of everyday life, a hammer is (sometimes dangerously) real. In the context of spacetime and quantum mechanics, the hammer as I experience it-- solid, flat, shiny-- doesn't really exist-- I'm really looking at 99.9999999% empty space, and the surface uniformity is an illusion.
In the context of ultimate truth, then the only answer is-- who knows? We don't have access to that.
So I'd say, yes there's truth, but no truth that can be independent of some context. Relativity ftw.
