 and honourable to our beloved science to correct oner's own 

 mistakes, admitting that one has altered his opinions for (at 

 least what one believes to be) the better, or that one has 

 gained new knowledge in the course of time, than to adhere 

 with obstinate consistency to what one has written before.

 one of the revelations brought home to zoologists by Darwin 

 and his school, and unless we close our eyes and ears
