In every thing there naturally grows
A balsamum to keep it fresh and new,
If 'twere not injur'd by extrinsique blows;
Your youth and beauty are this balm in you.
But you, of learning and religion,
And virtue and such ingredients, have made
A mithridate, whose operation
Keeps off, or cures what can be done or said.

Though the following lines of Donne, on the last night of the year, have something in them too scholastick, they are not inelegant:

This twilight of two years, not past nor next,
Some emblem is of me, or I of this,
Who, meteor-like, of stuff and form perplext,
Whose what and where in disputation is,
If I should call me any thing, should miss.
I sum the years and me, and find me not
Debtor to th' old, nor creditor to th' new.
That cannot say, my thanks I have forgot;
Nor trust I this with hopes; and yet scarce true
This bravery is, since these times shew'd me you.

Yet more abstruse and profound is Donne's reflection upon man as a microcosm:

If men be worlds, there is in every one
Something to answer in some proportion
All the world's riches: and in good men, this
Virtue, our form's form, and our soul's soul, is.

Of thoughts so far-fetched, as to be not only unexpected, but unnatural, all their books are full.

To a lady, who wrote poesies for rings:

They, who above do various circles find,
Say, like a ring, th' equator heaven does bind.
When heaven shall be adorn'd by thee,
(Which then more heaven than 'tis will be,)
'Tis thou must write the poesy there,
For it wanteth one as yet,
Then the sun pass through 't twice a year,
The sun, which is esteem'd the god of wit. COWLEY.

The difficulties which have been raised about identity in philosophy, are, by Cowley, with still more perplexity applied to love:

Five years ago (says story) I lov'd you,
For which you call me most inconstant now;
Pardon me, madam, you mistake the man;
For I am not the same that I was then:
No flesh is now the same 'twas then in me;
And that my mind is chang'd yourself may see.
The same thoughts to retain still, and intents,
Were more inconstant far; for accidents
Must of all things most strangely inconstant prove,
If from one subject they t' another move;
My members, then, the father members were,
From whence these take their birth which now are here.
If then this body love what th' other did,
'Twere incest, which by nature is forbid.
