So, when our mortal forms shall be disjoin’d. The lifeless lump uncoupled from the mind, From sense of grief and pain we shall be free, We shall not feel, because we shall not be.
Though earth in seas, and seas in heaven were lost We should not move, we should only be toss’d. Nay, e’en suppose when we have suffer’d fate The soul should feel in her divided state, What’s that to us? For we are only we While souls and bodies in one frame agree.
Nay, though our atoms should revolve by chance, And matter leap into the former dance, Though time our life and motion should restore, And make our bodies what they were before, What gain to us would all this bustle bring? The new-made man would be another thing.
