Santa comes down the chimney bearing gifts and emerging into the room places them under the tree. Anyone who doesn’t get the catenary of symbolism there from the gross Freudian and the breathy chanteuse “ hurry down the chimney tonight” to the gift and the gift bearer under the evergreen never dying tree needs to turn over a new leaf. Our daughter placed in my wife’s arms for the first time drew from her the words of wonder - “She’s so beautiful”. Unto us a child is given and we emulate that great truth with a myth evoking wonder in the form it can be experienced by the child. It is a balance of gifts which is the source of the need to sacrifice expressed in both the ancient and modern forms of religion.
We philosophers, we worry you know.
