All that man has to do is to live and die; the sum of humanity is comprehended by Donne in the following lines:

Think in how poor a prison thou didst lie
After enabled but to suck and cry.
Think, when ’twas grown to most, ’twas a poor inn,
A province pack’d up in two yards of skin,
And that usurp’d, or threaten’d with a rage
Of sicknesses or their true mother, age.
But think that death hath now enfranchised thee;
Thou hast thy expansion now, and liberty;
Think, that a rusty piece discharged is flown
In pieces, and the bullet is his own,
And freely flies: this to thy soul allow,
Think thy shell broke, think thy soul hatch’d but now.

They were sometimes indelicate and disgusting. Cowley thus apostrophises beauty:

Thou tyrant which leav’st no man free!
Thou subtle thief, from whom nought safe can be!
Thou murtherer, which has kill’d, and devil, which would’st damn me!

Thus he addresses his mistress:

Thou who, in many a propriety,
So truly art the sun to me,
Add one more likeness, which I’m sure you can,
And let me and my sun beget a man.

Thus he represents the meditations of a lover:

Though in thy thoughts scarce any tracts have been
So much as of original sin,
Such charms thy beauty wears, as might
Desires in dying confest saints excite.
Thou with strange adultery
Dost in each breast a brothel keep;
Awake all men do lust for thee,
And some enjoy thee when they sleep.

The true taste of tears:

Hither with crystal vials, lovers, come,
And take my tears, which are love’s wine,
And try your mistress’ tears at home;
For all are false, that taste not just like mine.—Donne.
