It is not that the French are not profound, but they all express themselves so well that we are led to take their geese for swans.

-Brooks,VanWyck
  From  A Writer's Notebook.

Clear writers, like clear fountains, do not seem so deep as they are; the turbid look the most profound.

-Landor,Walter Savage
  Imaginary Conversations of Literary Men and Statesmen, 'Southey and Porson'.

Alles, was tief ist, liebt die Maske. Everything profound loves the mask.

-Nietzsche, FriedrichWilhelm
  Jenseits von Gut und Bo«  se (Beyond Good and Evil), section 40 (translated by R  J Hollingdale).

In the final analysis, all architecture reveals the application of human ingenuity to the satisfaction of human needs. And among these needs are not only shelter, warmth and accommodation, but also the needs, felt at every moment in every part of the world in endlessly different ways, for something more profound, evocative and universal, for beauty, for permanence, for immortality.

-Nuttgens, Patrick
  'The Nature of  Architecture', in Ben Farmer and Hentie Louw (eds) Companion to Contemporary  Architectural Thought (1993).
