生存还是毁灭（To be, or not to be）是莎士比亚出戏哈姆雷特第三幕第一场，哈姆雷特王子一段句白的第一句；很多人也会用这句来指整段句白。它是世界文学中常见被引用的一句。而整段句白是：

"To be, or not to be: that is the question:

Whether 'tis nobler in the mind to suffer

The slings and arrows of outrageous fortune,

Or to take arms against a sea of troubles,

And by opposing end them? To die: to sleep;

No more; and by a sleep to say we end

The heart-ache and the thousand natural shocks

That flesh is heir to, 'tis a consummation

Devoutly to be wish'd. To die, to sleep;

To sleep: perchance to dream: ay, there's the rub;

For in that sleep of death what dreams may come

When we have shuffled off this mortal coil,

Must give us pause: there's the respect

That makes calamity of so long life;

For who would bear the whips and scorns of time,

The oppressor's wrong, the proud man's contumely,

The pangs of despised love, the law's delay,

The insolence of office and the spurns

That patient merit of the unworthy takes,

When he himself might his quietus make

With a bare bodkin? who would fardels bear,

To grunt and sweat under a weary life,

But that the dread of something after death,

The undiscover'd country from whose bourn

No traveller returns, puzzles the will

And makes us rather bear those ills we have

Than fly to others that we know not of?

Thus conscience does make cowards of us all;

And thus the native hue of resolution

Is sicklied o'er with the pale cast of thought,

And enterprises of great pitch and moment

With this regard their currents turn awry,

And lose the name of action.--Soft you now!

The fair Ophelia! Nymph, in thy orisons

Be all my sins remember'd".
