What is truth?

1. The Truth is... a riddle

What is something that humans seek, and don't know it when they see it?

The answer is the truth!

(C.f. Jacobellis v Ohio 1964 in which the judge declined to define hard-core pornography, but famously said "I know it when I see it".)

2. The Truth is... not known
 
The conundrum of seeking truth but not knowing it when we see it is embedded in the idea of knowledge as justified true belief

It is said that we know something to be true if 
    (a) we believe it to be true, 
    (b) we have justification for our belief, and 
    (c) it is true.

We can build towards knowledge 
with beliefs and justifications, 
but we fail unless it's true.

And how do we "know" if it's true? 
 
Whether something is true is... unknown. 

Frustrating!
