The Human Seasons

Four Seasons fill the measure of the year;
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: quiet coves His soul has in its Autumn, when his wings He furleth close; contented so to look On mists in idleness—to let fair things Pass by unheeded as a threshold brook:— He has his Winter too of pale misfeature, Or else he would forego his mortal nature.

John Keats
