The Queen describes Hamlet's rage in these words:--

And thus awhile the fit will work on him;
Anon, as patient as the female dove,
When that her golden couplets are disclosed,
His silence will sit drooping. [49]

In the meantime, the fire with which Hamlet's soul had been seized,
is gone, like a flash of lightning. He changes to another point of
view--probably that one according to which everything goes its way
in compliance with a heavenly decree. The little verse he recites in
parting:--

Let Hercules himself do what he may,
The cat will mew and dog will have his day,

quite corresponds to such a passive philosophy which has gained the
mastery over him, and to which he soon falls a victim.

We are approaching the conclusion of the great drama. Here, again, in
order to explain Hamlet's action, or rather his yielding to influences
around him, we have to direct the attention of the reader to Essay
(III. 10), in which Montaigne tells how easily he protects himself
against the dangers of inward agitation by dropping the subject which
threatens to become troublesome to him before he is drawn on and carried
along by it. The doughty nobleman says that he has escaped from
many difficulties by not staking frivolously, like others, happiness
and honour, life and everything, on his 'rapier and his dagger.' [50]
