The Dread of Something After Death

Maybe Shakespeare understood it the best when he wrote:

[.....]To dye to sleepe,

To sleepe, perchance to Dreame; I, there's the rub,

For in that sleepe of death, what dreames may come,

When we haue shuffel'd off this mortall coile,

Must giue vs pawse. There's the respect

That makes Calamity of so long life [....]

To grunt and sweat vnder a weary life,

But that the dread of something after death,

The vndiscouered Countrey, from whose Borne

No Traueller returnes, Puzels the will,

And makes vs rather beare those illes we haue,

Then flye to others that we know not of.

Thus Conscience does make Cowards of vs all [....]

(Hamlet, Act III, Scene I)

After all, don't we mummify people, stick them in cement-lined holes, and/or believe in some mystical afterlife?
