There is a deep similarity between the union of the soul and body and the mystery of the family. In both cases we are in the presence of the same fact, or rather something which is far more than a fact since it is the very condition of all facts whatever they may be: I mean incarnation. I am not, of course, using this term in its theological sense. It is not a question of our Lord’s coming into the world, but of the infinitely mysterious act by which an essence assumes a body, an act around which the meditation of a Plato crystallised, and to which modern philosophies only cease to give their attention in so far as they have lost the intelligence’s essential gift, that is to say the faculty of wonder.
