ACT IV, Sc. 4, Lines 34-58: Sum up what Hamlet thinks of Fortinbras in lines 48-58

Hamlet. Examples gross as earth exhort me,

Witness this army of such mass and charge,

Led by a delicate and tender prince,

Whose spirit, with divine ambition puffed,

Makes mouths at the invisible event,

Exposing what is mortal and unsure

To all that fortune, death, and danger dare,

Even for an eggshell. Rightly to be great

Is not to stir without great argument,

But greatly to find quarrel in a straw

When honour's at the stake.
