Plantinga argues that whereas a God would be expected to create beings with reliable reasoning faculties, evolution would be just as likely to lead to unreliable ones, meaning that if evolution is true, it is irrational to trust whatever reasoning one relies on to conclude that it is true.
Plantinga argumenta que mentres que se esperaría que un Deus crease cousas con facultades de razoamento fiables, sería igual de probable que a evolución conducise a facultades non fiables, o que significa que se a evolución é verdadeira, é irracional confiar en ningún razoamento no que un se basee para concluír que é certa.
