Nothing can come of nothing: speak again.

I am a man more sinned against than sinning.

When we are born, we cry that we are come to this great stage of fools.

Is man no more than this? Consider him well. Thou owest the worm no silk, the beast no hide, the sheep no wool, the cat no perfume.

I will do such things, what they are, yet I know not: but they shall be the terrors of the earth.

Speak what we feel, not what we ought to say.

The worst is not so long as we can say 'This is the worst.'

Men must endure their going hence, even as their coming hither.

O, let me not be mad, not mad, sweet heaven; I would not be mad. Keep me in temper; I would not be mad.

Thou art a soul in bliss, but I am bound upon a wheel of fire, that mine own tears do scald like molten lead.

'Tis the times' plague, when madmen lead the blind.

How sharper than a serpent's tooth it is to have a thankless child!

King Lear
