If one ventures to publish a book on the Cat, it is an obvious prerequisite for him to publish another on the Dog. Needless to say, there is a great difference between the Cat and the Dog. If the one is *catty~, the other is *dogged~. If the one is solitary, the other is *man*s best friend~. If the one is a philosopher, the other is a theologian, at least one who goes in for *dog-matic~ theology.
