There are four seasons in the mind of man: He has his lusty Spring,when fancy clear Takes in all beauty with an easy span: he has his Summer,when luxuriously Spring's honeyed cud of youthful thought he loves to ruminate,and by such dreaming high Is nearest unto heaven:quite coves His soul has in its Autumn,when his wings He furls close;contented so to look On mists in idleness-to let fair things Pas by unheeded as a threshold brook.

春夏秋冬把一年的时间填满，人的心灵也包含着四个季节。在他朝气蓬勃的春天，那清晰的幻想在一瞬间就把所有的美轻易囊括。在他的夏天，他喜欢用年轻思想把春天里采的花蜜反复品位，细细欣赏那蜜汁的甘甜芳香，乘着这高远的梦想冲天而飞。他心灵的秋天有如小湾安谧，这时他心满意足地收拢翅膀，悠闲地凝视着雾色--而美好的事物犹如门前的小溪悄然而逝。
