The Tragedy of King Lear - V:4.6.75

LEAR I am a very foolish, fond old man.
Fourscore and upward,
Not an hour more nor less; and to deal plainly,
I fear I am not in my perfect mind.
Methinks I should know you and know this man;
Yet I am doubtful: for I am mainly ignorant
What place this is, and all the skill I have
Remembers not these garments, nor I know not
For, as I am a man, I think this lady
To be my child Cordelia.
