I said I splendidly loved you; it's not true. 
Such long swift tides stir not a land-locked sea. 
On gods or fools the high risk falls -- on you -- 
The clean clear bitter-sweet that's not for me. 
Love soars from earth to ecstasies unwist. 
Love is flung Lucifer-like from Heaven to Hell. 
But -- there are wanderers in the middle mist, 
Who cry for shadows, clutch, and cannot tell 
Whether they love at all, or, loving, whom: 
An old song's lady, a fool in fancy dress, 
Or phantoms, or their own face on the gloom; 
For love of Love, or from heart's loneliness. 
Pleasure's not theirs, nor pain.  They doubt, and sigh, 
And do not love at all.  Of these am I.
Rupert Brooke
