 at all, and thus a sense of needs and of the gratification 

 of those needs, and thus hope and fear, and a sense of 

 content and discontent — given also the lowest power of 

 gratifying those needs — given also that some individuals L 

 have these powers in a higher degree than others — given

 extent of time — and the whole phenomena of species 

 and genera resolve themselves into an illustration of the 

 old proverb, that what is one man's meat is another 

 man's poison. Life in its lowest form under the above 

 conditions — and we cannot conceive of life at all without 

 them — would be bound to vary, and to result after 

 not so very many millions of years in the infinite forms 

 and instincts which we see around us.
