Shakespeare on Hot States and Cold States (I)

I do believe you think what now you speak;

But what we do determine oft we break.

Purpose is but the slave to memory,

Of violent birth, but poor validity;

Which now, like fruit unripe, sticks on the tree,

But fall unshaken when they mellow be.

Most necessary 'tis that we forget

To pay ourselves what to ourselves is debt.

What to ourselves in passion we propose,

The passion ending, doth the purpose lose.

The violence of either grief or joy

Their own enactures with themselves destroy.

Where joy most revels, grief doth most lament;

Grief joys, joy grieves, on slender accident.

(Hamlet, Act 3, Scene 2, Lines 2078-2091)

Not that I think you did not love your father;

But that I know love is begun by time,

And that I see, in passages of proof,

Time qualifies the spark and fire of it.

There lives within the very flame of love

A kind of wick or snuff that will abate it;

And nothing is at a like goodness still;

For goodness, growing to a plurisy,

Dies in his own too-much. That we would do,

We should do when we would; for this 'would' changes,

And hath abatements and delays as many

As there are tongues, are hands, are accidents;

And then this 'should' is like a spendthrift sigh,

That hurts by easing.

(Hamlet Act 4, Scene 7, Lines 3254-3267)
