Revisability of convictions
Beliefs about the divine should remain open to revision.
What it is: Agnosticism tends to treat metaphysical convictions as revisable in light of new arguments, experiences, or critiques.
How the position understands it: Openness to revision is seen as an intellectual virtue, avoiding premature closure in positive or negative dogmas.
Basis and context: This attitude dialogues with philosophical fallibilism and the scientific practice of public correction.
Debates and variations: Some agnostics consider it only method; others transform it into a permanent existential posture.
