Presumed Degrees of Truth.—One of the most usual errors of deduction is: because someone truly and openly is against us, therefore he speaks the truth. Hence the child has faith in the judgments of its elders, the Christian in the assertions of the founder of the church. So, too, it will not be admitted that all for which men sacrificed life and happiness in former centuries was nothing but delusion: perhaps it is alleged these things were degrees of truth. But what is really meant is that, if a person sincerely believes a thing and has fought and died for his faith, it would be too unjust if only delusion had inspired him. Such a state of affairs seems to contradict eternal justice. For that reason the heart of a sensitive man pronounces against his head the judgment: between moral conduct and intellectual insight there must always exist an inherent connection. It is, unfortunately, otherwise: for there is no eternal justice.
