This having learnt, thou hast attained the sum Of wisdom; hope no higher, though all the stars Thou knew'st by name, and all th'ethereal powers, All secrets of the deep, all nature's works, Or works of God in heav'n, air, earth, or sea, And all the riches of this world enjoy'dst, And all the rule, one empire; onlyadd Deeds to thy knowledge answerable, add faith, Add virtue, patience, temperance, add love, By name to come called charity, the soul Of all the rest: then wilt thou not be loath To leave this Paradise, but shalt possess A paradise within thee, happier far.
'Paradise Lost' (1667) bk. 12, l. 581
