So much one man can do,
That does both act and know.
Upon Cromwell’s Return from Ireland.  A. MARVELL.

DEFEAT.

   Yes, this is life; and everywhere we meet,
   Not victor crowns, but wailings of defeat.
The Unattained.  E.O.  SMITH.

At a frown they in their glory die. 
The painful warrior, famoused for fight,
After a thousand victories once foiled,
Is from the books of honor razed quite,
And all the rest forgot for which he toiled.
Sonnet XXV.  SHAKESPEARE.

What though the field be lost? 
All is not lost; the unconquerable will,
And study of revenge, immortal hate,
And courage never to submit or yield. 
And what is else not to be overcome.
Paradise Lost, Bk.  I.  MILTON.

Unkindness may do much;
And his unkindness may defeat my life,
But never taint my love.
Othello, Act iv.  Sc. 2.  SHAKESPEARE.

They never fail who die
In a great cause.
Marino Faliero, Act ii.  Sc. 2.  LORD BYRON.

DESPAIR.

So farewell hope, and, with hope, farewell fear,
Farewell remorse:  all good to me is lost;
Evil, be thou my good.
Paradise Lost, Bk.  IV.  MILTON.

No change, no pause, no hope!  Yet I endure. Prometheus Unbound, Act i.  P.B.  SHELLEY.

         The strongest and the fiercest spirit
   That fought in heaven, now fiercer by despair.
Paradise Lost, Bk.  II.  MILTON.

I am one, my liege,
Whom the vile blows and buffets of the world
Have so incensed, that I am reckless what
I do to spite the world.
Macbeth, Act iii.  Sc. 2.  SHAKESPEARE.

Beware of desperate steps.  The darkest day,
Live till to-morrow, will have passed away.
Needless Alarm.  W. COWPER.

DEVIL.

  I called the devil, and he came,
  And with wonder his form did I closely scan;
  He is not ugly, and is not lame,
    But really a handsome and charming man. 
  A man in the prime of life is the devil,
  Obliging, a man of the world, and civil;
  A diplomatist too, well skilled in debate,
  He talks quite glibly of church and state.
Pictures of Travel:  Return Home.  H. HEINE.

The Devil was sick, the Devil a monk would be;
The Devil was well, the Devil a monk was he.

He must needs go that the devil drives. All’s Well that Ends Well, Act i.  Sc. 3.  SHAKESPEARE.

The prince of darkness is a gentleman. King Lear, Act iii.  Sc. 4.  SHAKESPEARE.

             The devil hath power
  To assume a pleasing shape.
Hamlet, Act ii.  Sc. 2.  SHAKESPEARE.

And oftentimes, to win us to our harm,
The instruments of darkness tell us truths;
Win us with honest trifles, to betray us
In deepest consequence.
Macbeth, Act i.  Sc. 3.  SHAKESPEARE.
