EXTRACT FROM PREFACE. 



"I shall try to show that life is response to the order of nature; in fact, tliis 

 thesis is the text of most of the lectures : but if it be admitted, it follows that 

 biology is the study of response, and that the study of that order of nature to 

 which response is made is as well within its province as the study of the living or- 

 g.inism which responds, for all the knowledge we can get of both these aspects of 

 nature is needed as a preparation for the study of that relation between them which 

 constitutes life. Our interest in all branches of science is vital interest. It is only 

 as living things that we care to know. Life is that which, when joined to mind, is 

 knowledge, — knowledge in use; and we may be sure that all living things with 

 minds like ours are conscious of some part of the order of nature, for the response 

 in which life consists is response to this order. The statement that physical 

 phenomena are natural seems to mean little, but the phenomena of life are so 

 wonderful that many hesitate, even at the present day, to believe that nature can be 

 such a wonderful thing as it must be if the actions of all living things are natural; 

 and, as I shall try to find out in this course of lectures what we mean by the asser- 

 tion that living nature is natural, I shall now attempt, by a few illustrations, to give 

 a broad outline of some of the most notable features of the nature of living things ''
