Some Comments on the Method of Kyhl (Correspondence and Author´s Reply)

The purpose of this letter is not to criticize the philosophy of Kyhl´s method nor even to engage in a debate as to whether his method is, or is not, more useful than ours. We find his proposals both interesting and meaningful. First, we would like to call attention to two errors in his letter and then to show the close relation of his method to ours.
