A stopped clock is not right twice a day - it is never right; because it never knows it is right.
It is knowing that is everything - and knowing is a matter of provenance: that is, a matter of where the knowledge comes from - its lineage.
A distorted version of this view is common - perhaps normal - among unreflective scientists, who regard provenance in terms of 'evidence'; begging the question of what counts as evidence.
But the corruption of science shows us that what counts as evidence, what counts as correct interpretation of evidence, is part of a circularity of definition which pre-decides all questions.
This is why we cannot, nowadays, avoid explicit metaphysics. We can no longer take metaphysics for granted (that genie is out of the bottle) - nor can we pretend that evidence supersedes metaphysics (unless we are happy to accept that hermetically-sealed bureaucratic careerism really-is science).
So we can only be right on the basis of true metaphysics, true basic-assumptions - and true basic assumptions can only be known (here and now) by the direct and intuitive knowing of our divine selves.
So it is that specific provenance - direct knowing of our divine selves - which is the sole guarantor of truth.
