Theology, in the nature of the case, must use analogies to express the relation between man and God. In the past religious analogies have been those of politics, of paternity, or of law. The rise of the biological sciences has affected all types of thinking and has given a new group of analogies as well as technical terms to other sciences than this. It is in the hope of assisting theology to appropriate this dominant type of thinking that the Biblical World will occasionally print articles dealing with biological matters. The present article by a distinguished botanist contains a description of the life process, which abounds in suggestive parallels to that of spiritual life. Indeed, one cannot help inquiring whether they may not be something more than analogies.
