Identify four features of metaphysical poetry in "The Definition of Love" by Andrew Marvell.

"The Definition of Love" is a seventeenth-century British metaphysical poem by Andrew Marvell. It exemplifies a number of characteristics associated with metaphysical poetry, as it is 1) witty, 2) highly cerebral, 3) of mixed tone, being comic yet serious, 4) prone to the use of paradox and abstraction, and finally, 5) daring in its prosody, especially its use of rhyme.
The definition of the speaker's love as being of rare birth because it is "begotten by Despair / Upon Impossibility" sets a comic tone from the outset. Much human love is grounded in impossibility and evocative of despair—hence, such love is not rare at all. It is, in fact, quite common. The comedy of the poem lies in the speaker's attempt to dignify his unrequited love and pretend to himself that it is rare (and thus, special) because it is doomed to failure. That is the only thing that is special about "my love," and it is not very special at all. No wonder that the speaker must intellectualize his love and attempt to arrive at a highly abstract "definition" of it. His love eludes his emotional grasp, and so he must strive to capture it through definition.
