Ultimate reality is, as the name suggests, ultimate.

Supreme.

Transcedent.

Unsurpassable.

In a world full of relativism, truth claims are altogether rejected. Philosopically, it makes no sense. Altogether rejecting something ultimate to replace it with something relative is itself ultimate.

There’s no way around it in the end. We can go around in circles forever, but ultimately, the universe has to have an ultimate truth, an ultimate reality.
