Exigência de evidência proporcional
Afirmações metafísicas exigem justificação proporcional à sua pretensão.
O que é: Muitas formulações agnósticas defendem que afirmações sobre Deus precisam de razões suficientemente fortes antes de serem aceitas como conhecimento.
Como a posição entende: A convicção deve acompanhar a qualidade da evidência, e não apenas tradição, autoridade ou desejo subjetivo.
Base e contexto: Esse princípio dialoga com evidencialismo, crítica da credulidade e cultura científica moderna.
Debates e variações: Correntes religiosas e pragmatistas contestam que toda crença relevante dependa do mesmo tipo de prova.
