In "To His Coy Mistress," the poem can be reduced into if, then, but, and therefore. Can someone help me figure it out? If- Then- But- Therefore-

Marvell's invitational lyric, To His Coy
Mistress, uses the syllogistic structure of if
(then)-but-therefore to work out the ancient Classical theme of
carpe diem to metaphysical transcendence. The speaker addresses his
beloved, who is not prepared to surrender in love, in the form of a syllogistic
argument. The argument is in three parts.

IF
the lovers had enough space and time, they could have gone for all the
paraphernalia of traditional romantic love-making, for they would have been in no
hurry.

BUT in reality,Time
runs fast, and chases every human being as the hunter pursues the hunted. As and when
the beloved dies and lies in the grave, all her love is gone unfulfilled, just as all
the passions of the lover get burnt
up.

THEREFORE, the lovers
should utilize the moment without bothering for eternity. They should make love with all
the strength and energy of 'amorous birds of prey', not as victims but as victors,
running with the sun, united in love.
