The baroque refers to the era situated somewhere between the 17th and 18th centuries. Since the baroque experienced radical social, cultural, political and economical transformations, it can be defined as ``periods of crisis`` or ``moments of transition,`` and ``the space for inaugurating new beginnings.`` Both John Donne (1572-1631) and Gottfried Wilhelm Leibniz (1646-1716) lived in this transhistorical, transcultural era called the baroque. Although it is not sure whether they both knew each other`s existence then, John Donne`s poems can be said to be closely related to Leibniz`s ``Monad`` philosophy. That is because they share the baroque mentality and sensibility, such as ``monad individuals``, ``a perfect correspondence between the microcosm and the macrocosm``, ``reconciliation between body and soul``, ``preference for variety, diversity, change`` and ``emphasis on solidarity and harmony.`` In fact, the contemporary society consists of monad individuals, which reminds us of the baroque individuals. Considering this aspect, this paper aims to associate John Donne`s poems with the baroque philosopher Leibniz`s Monadology and also the neo-baroque philosopher Gilles Deleuze`s ``Monad`` and ``The Fold`` in order to enhance our understanding of the (neo-) baroque era. That is, the baroque should be considered not only as a phenomenon of the 17th but also, more broadly, as a transhistorical that has had wider historical repercussions. That might be why we need to still read John Donne`s poems and look into our lives through his poems. As Deleuze writes of the "new baroque," appreciating John Donne`s poems, we can discover new way of our own folding, akin to new environment.
