The poem  If  by Rudyard Kipling it is also one of my favorite poems!  

well, i find Keats a very interesting poet, very philosophical and spritiual in a way.
I always liked his Odes!
I recommend him highly, that is if you are into philosophical quiestions of beauty, love, death and many other essential questions!

Thomas Hardy because he wrote effective and striking poetry in a very interesting period of British history.
