Yes, yes, the negative accord is sufficient.

The feeling that the Church of Christ is suffering is sufficient to unite us in the love of our Mother, and to move us at least to pray for her, we and our brothers who, like us, feel her sufferings! What is your answer, Abbe ?" The Abbe murmured with a faint smile: "_C'est beau, mais ce n'est pas la logique_." Don Paolo started up: "Logic has nothing to do with it." "Ah!" Marinier replied, assuming a contrite expression, "if you intend to forego logic----!" Don Paolo, all on fire, wished to protest, but Professor Dane signed to him to be calm.
"We do not intend to forego logic," said he, "but it is not as easy to measure the logical value of a conclusion in questions of sentiment, of love of faith, as it is to measure the logical value of a conclusion in geometrical problems.

In the questions which interest us the logical process is hidden.

Surely my dear friend Marinier, one of the most acute-minded men I know, when he answered my dear friend Selva, did not intend to imply that when a person very dear to us falls ill, it is necessary for us to decide what method of treatment to adopt before hastening to his bedside together." "These are very fine figures," said the Abbe Marinier with vehemence; "but you are all aware that similes are not arguments!" Don Clemente, standing in the corner between the door leading into the corridor and the window, and Professor Minucci, seated near him, began to speak at the same moment, but both stopped short; each wishing to allow the other to speak first.

Selva proposed that the monk be heard first.
