This capacity for objectivity and absoluteness amounts to an existential — and “preventive” — refutation of the ideologies of doubt: if a man is able to doubt, it is because there is certainty; likewise the very notion of illusion proves that man has access to reality. It follows that there are necessarily some men who know reality and who therefore have certainty; and the great spokesmen of this knowledge and certainty are necessarily the best of men. For if truth were on the side of doubt, the individual who doubted would be superior not only to these spokesmen, who have not doubted, but also to the majority of normal men across the millennia of human existence. If doubt conformed to the real, human intelligence would be deprived of its sufficient reason, and man would be less than an animal, for the intelligence of animals does not doubt the reality to which it is proportioned.
