"You insist," wrote Perthes to a friend, "on respect for learned men. I say, Amen! But, at the same time don't forget that largeness of mind, depth of thought, appreciation of the lofty, experience of the world, delicacy of manner, tact and energy in action, love of truth, honesty, and amiability ---

that all these may be wanting in a man who may yet be very learned." Samuel Smiles
