WHAT EVOLUTION IS NOT. / 



birth to a cow or a cow to a horse. Seasons change, 

 but midsummer never changes to midwinter, or the re- 

 verse, except by gradual stages. Life is conservative 

 and changes slowly, but must constantly change. 



IV. Not "an innate tendency toward progression." 

 Degeneration in Evolution as well as progress. Di- 

 vergence and adaptation not necessarily progress. 

 Gradation not necessarily progression. 



V. Not spontaneous generation. Ancient belief in 

 spontaneous generation. Modern belief in it. Tyn- 

 dall's experiments. No evidence that generation ever 

 occurs without parentage. Theoretical argument for 

 it. How else could life begin ? We do not know 

 how, or where, or when life began. Theoretical evi- 

 dence against spontaneous generation. If occurring 

 once would occur again under like conditions. All 

 life seems bound in unity, as if arising from one com- 

 mon stock. Spontaneous generation implies many 

 stocks. If spontaneous generation exists we would 

 have no means of recognizing it. Spontaneous forma- 

 tion of protoplasm an organism fresh from mint of 

 creation would be too small too simple for recog- 

 nition by any human instrumentality. Size of a 

 molecule of protoplasm. 



VI. Not identical with the Hindoo theories of re- 

 incarnation. Science not advanced by speculative 

 philosophy or by philosophic meditation. 



VII. Not a creed or body of doctrine to be believed 

 without being understood. 



VJ1I. Not a new religion, " the religion of the future." 



IX. Not to be controverted by authority in the name 



of philosophy, theology, or religion. " Roma locuta est :
