Beginning with the certainties of everyday experience, it reaches theism at last by means of an analogical argument.
But fuller conceptions of evolution raise further difficulties for intuitionalism in its wonted forms. Knowledge cannot be divided into the two components - immediate certainties, precarious inferences.
Negatively, " unchallenged historical certainties " are becoming few in number, or are disappearing altogether, through the industry of modern minds.
Even the Roman Catholic Church produced the Abbe Loisy (though he undertakes to play off church certainties against historical uncertainties).
Again, the assertion that the church is infallible upon some questions, not belonging to the area of revelation (properly so-called in Roman Catholic theology), destroys the identification of " dogmas " with " infallible certainties " which we noted both in the Protestant schoolmen and in Chrismann.
