Cleave ever to the sunnier side of doubt, And cling to faith beyond the forms of faith; She reels not at 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 for the 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!"
Alfred Lord Tennyson
