"But if you take ready mixing as your test of power," said Pash, "some of the least practical ideas beat everything. They spread without being understood, and enter into the language without being thought of."
"They may act by changing the distribution of gases," said Marrables; "instruments are getting so fine now, men may come to register the spread of a theory by observed changes in the atmosphere and corresponding changes in the nerves."
"Yes," said Pash, his dark face lighting up rather impishly, "there is the idea of nationalities; I dare say the wild asses are snuffing it, and getting more gregarious."
"You don't share that idea?" said Deronda, finding a piquant incongruity between Pash's sarcasm and the strong stamp of race on his features.
"Say, rather, he does not share that spirit," said Mordecai, who had turned a melancholy glance on Pash. "Unless nationality is a feeling, what force can it have as an idea?"
"Granted, Mordecai," said Pash, quite good-humoredly. "And as the feeling of nationality is dying, I take the idea to be no better than a ghost, already walking to announce the death."
"A sentiment may seem to be dying and yet revive into strong life," said Deronda. "Nations have revived. We may live to see a great outburst of force in the Arabs, who are being inspired with a new zeal."
"Amen, amen," said Mordecai, looking at Deronda with a delight which was the beginning of recovered energy: his attitude was more upright, his face was less worn.
"That may hold with backward nations," said Pash, "but with us in Europe the sentiment of nationality is destined to die out. It will last a little longer in the quarters where oppression lasts, but nowhere else. The whole current of progress is setting against it."
"Ay," said Buchan, in a rapid thin Scotch tone which was like the letting in of a little cool air on the conversation, "ye've done well to bring us round to the point. Ye're all agreed that societies change--not always and everywhere--but on the whole and in the long run. Now, with all deference, I would beg t' observe that we have got to examine the nature of changes before we have a warrant to call them progress, which word is supposed to include a bettering, though I apprehend it to be ill-chosen for that purpose, since mere motion onward may carry us to a bog or a precipice. And the questions I would put are three: Is all change in the direction of progress? if not, how shall we discern which change is progress and which not? and thirdly, how far and in what way can we act upon the course of change so as to promote it where it is beneficial, and divert it where it is injurious?"
