The only intelligble definition of truth is that found in our brain biology. The brain generates feelings of certitude when it observes stable regularities in the world. This is how the brain marks knowledge: it pairs facts with a positive feeling, and such facts seep into our subconscious. So, the brain's threshold of truth is reliability. The brain is practical. If something appears reliable, the brain takes it as truth.
Now, to go beyond this definition and look for some higher definition of truth is pure folly, and pure imagination. How would we ever know if we arrived at such mythical higher truth without using the brain's existing threshold of truth, which would make the process circular and contradictory.
It's true that we can never be sure that our brain is accurately perceiving the world e.g. we may be a brain in a vat, or in an experience machine, or everyone else may be a zombie, etc. But there is no way to solve these hypothetical realities. They may actually be true. We can never know. So, without any arbitrating criteria, we simply have to choose one reality to live with. And it's no surprise that everyone will choose the apparent reality in front of their eyes.
