Since grief but aggravates thy loss,
Grieve not for what is past. [ Percy ]

Of that which once was great is passed away. [ Wordsworth ]

Is it not well to pass away ere life has lost its brightness? [ Lady Flora Hastings ]

I may grieve with the smart of an evil as soon as I feel it, but I will not smart with the grief of an evil as soon as I hear of it. My evil, when it Cometh, may make my grief too great; why, then, should my grief, before it comes, make my evil greater? [ Arthur Warwick ]

When I look upon the tombs of the great, every motion of envy dies; when I read the epitaphs of the beautiful, every inordinate desire forsake me: when I meet with the grief of parents upon a tombstone, my heart melts with compassion; when I see the tombs of the parents themselves, I reflect how vain it is to grieve for those whom we must quickly follow; when I see kings lying beside those who deposed them, when I behold rival wits placed side by side, or the holy men who divided the world with their contests and disputes, I reflect with sorrow and astonishment on the frivolous competitions, factions, and debates of mankind. [ Addison ]
