Am not thyself in converse with thyself,
For nothing worthy proving can be proven
Nor yet disproven. Wherefore be thou wise,
Cleave ever to the sunnier side of doubt,
And cling to Faith beyond the forms of Faith!
She reels not in the storm of warring words,
She brightens at the clash of 'Yes' and 'No,'
She sees the best that glimmers through the worst,
She feels the sun is hid but for a night,
She spies the summer through the winter bud,
She tastes the fruit before the blossom falls,
She hears the lark within the songless egg,
She finds the fountain where they wailed 'Mirage!'"
