Obtuseness

"Only connect the prose and the passion, and both will be exalted and human love will be seen at its hihghest. Live in fragments no longer. (...) Nor was the message difficult to give. (...) But she failed. For there was one quality in Henry for which she was never prepared: his obtuseness. He simply did not notice things and ther was no more to be said."

(E.M.Forster, Howards End, p.188)
