Read this passage:

ah, love, let us be true
to one another! for the world, which seems
to lie before us like a land of dreams,
so various, so beautiful, so new,
hath really neither joy, nor love, nor light,
nor certitude, nor peace, nor for pain;
and we are here as on a darkling plain
swept with confused alarms of struggle and flight,
where ignorant armies clash by night
