Why is truth true? (Note that I didn’t say the truth, about a particular thing: I said truth itself.) There are some reflexive properties, you see, the premise of which involves a sort of causal absurdity, are there not? In order for the question, “Why does existence exist?” to make any sort of sense, you have to predicate existence upon...well, upon itself. It’s like asking, “Why is the color green…green?” It isn’t. That sounds redundant; in actual fact it’s nonsensical. “Green” is a trait or predicate which other things possess, not the color green itself. How could anything describe itself? How can anything be its own basis? That’s basically tantamount to self-causation. Just as the mother doesn’t give birth to her own self, so does motherhood not describe itself. In the same way existence doesn’t apply to itself either. And so “why does existence exist?” is an invalid question, for the same reason that, “Why is truth true?” is.
