Aestheticism And Radicalism Must Lead Us To Jettison Reason, And To Replace It By A Desperate Hope For Political Miracles. This Irrational Attitude Which Springs From Intoxication With Dreams Of A Beautiful World Is What I Call Romanticism. It May Seek Its Heavenly City In The Past Or In The Future; It May Preach 'back To Nature' Or 'forward To A World Of Love And Beauty'; But Its Appeal Is Always To Our Emotions Rather Than To Reason. Even With The Best Intentions Of Making Heaven On Earth It Only Succeeds In Making It A Hell - That Hell Which Man Alone Prepares For His Fellow-men.
