EVOLUTION. 



LECTURE I. 



THE UNROLLING OF THE UNIVERSE. ORGANIC EVO- 

 LUTION : THE DEVELOPMENT OF FORMS OF LIFE. 



/. Evolution Considered as a Science. The study 

 of changing beings as affected by unchanging laws. 



" Nothing endures save the flow of energy and the 

 rational order that pervades it." - - Huxley. No one 

 dipping his hand in the river can be twice wet with 

 the same water. Shortness of human life as compared 

 with duration of world processes. Objects seen by a 

 flash of lightning during a storm appear immov- 

 able. So the phases of nature seem unchanged to the 

 casual observer. His view so short. Parable of the 

 rose and lily who thought the gardener immortal. 

 ; ' Dauer im Wechsel ": persistence in change. 



Epochs in science study. " Die neue Weltan- 

 schauung." 



Seeing the objects in nature. (1) As they appear. 

 (2) As they really are. (3) As they were (4) As 

 they are, their present condition being an inevitable 

 result of what they were, the laws of their being lead- 

 ing on to what they are to be.
