Quote by Michael Servetus: “Error is not a crime; the crime is to persist in error after it has been shown.”

Being wrong is a normal part of thinking. What matters morally is whether you are willing to update your beliefs when evidence contradicts them. Stubbornly defending a known mistake — out of pride, fear, or self-interest — is the real failure of intellectual honesty.

Servetus published his first theological work On the Errors of the Trinity in 1531, during the height of the Reformation, when every major theological position was contested at the cost of life. His willingness to say the dominant tradition was simply wrong made him enemies on every side.

Spanish theologian and physician who made important early contributions to the description of pulmonary circulation and wrote controversial theological works rejecting the doctrine of the Trinity. He was burned at the stake in Calvinist Geneva in 1553, making him a symbol of religious intolerance.
