"Like everyone else, I was familiar with Erhard's heavy bulk, and I knew his reputation for stubbornness. But when I met him, I found that he was subtle and highly intelligent – although we did not always agree. The prestige he enjoyed was well deserved: he had shown clear-sighted courage in successfully imposing and carrying out his ideas. He had no reason to doubt the superiority of the so-called ‘liberal’ economic policies that had worked so well in his own country. He was no nationalist, but the Schuman Plan had no place in his vision of an international economy based on pure free trade. Where we were proposing a code of good conduct, he scented the danger of dirigisme; where we were organizing European solidarity, he suspected protectionism."
