What animals and man have in common is, first of all, sensorial and instinctual intelligence, then the faculties of the senses, and finally basic feelings. What is proper to man alone is the intellect open to the Absolute; and also, owing to that very fact, reason, which extends the Intellect in the direction of relativity; and consequently it is the capacity for integral knowledge, for sacralization, and for ascension. Man shares with animals the wonder of subjectivity − but strangely a wonder that is not understood by the evolutionists; however, the subjectivity of animals is only partial, whereas that of man is total; the sense of the Absolute coincides with totality of intelligence.
