Not less weak than Montaigne's trust in human reason is that of Hamlet
when he fears 'the pales and forts of reason' may be broken down--

by the o'ergrowth of some complexion.

With such a mode of thought it is not to be wondered at that he should
welcome the first occasion when the task of his life may be revealed
to him by a heavenly messenger. Hoping that 'the questionable shape'
would not let him 'burst in ignorance,' but tell him why 'we fools of
Nature so horridly shake our disposition with thoughts beyond the
reaches of our souls,' he follows the spectral apparition. Good Horatio
does his best to restrain his friend, who has waxed 'desperate with
imagination,' from approaching the 'removed ground,' that might deprive
him of the 'sovereignity of reason,' and whither the Ghost beckons him.

Without more motive, into every brain

And hears it roar beneath.
