Truth

what is "Truth"? how do we know if something is true? what criteria do we take to define what something is true? that we can experience it, see it, touch it? but we know how our senses often mislead us. then how?

how do we know? we do we know that we know? what makes for meaningful life? how does one lead a meaningful life?

how do we go about finding answers to these questions? is there even a point to finding the answers to these questions?
