A good poem from Bemerton's second greatest poet (the first, of course, being George Herbert), the philosopher and British Malebranchean, John Norris.
A Collection of Miscellanies Consisting of Poems, Essays, Discourses and Letters, Occasionally Written By John Norris
UPDATE: Michael Gilleland gives the Latin (from Seneca) on which Norris's poem is based. You can also compare it with Andrew Marvell's riff on the same.
