 based not only the higher manifestations of the mind, but 

 the very permanence of the specific differences which 

 characterize every organism. Most of the arguments of 

 philosophy in favour of the immortality of man apply 

 equally to the permanency of this principle in other living 

 beings. May I not add, that a future life, in which man 

 would be deprived of that great source of enjoyment and 

 intellectual and moral improvement which result from 

 the contemplation of the harmonies of an organic world, 

 would involve a lamentable loss. And may we not look 

 to a spiritual concert of the combined worlds and all their 

 inhabitants in presence of their Creator, as the highest 

 conception of paradise ?
