| words. The more words he remembers, the |
| cleverer do his fellows esteem him. He  |
| looks upon the great transformations of |
| the world, but he does not see them as  |
| they were seen when man looked upon     |
| reality for the first time. Their names |
| come to his lips and he smiles as he    |
| tastes them, thinking he knows them in  |
| the naming."                            |
