These appeals were in vain, although they were made in language most attractive, and although the sympathies of the people were sincere and active in behalf of Hungary. His mission was a failure, inasmuch as neither by argument, by eloquence, nor by sympathy was he able to secure an official declaration or promise of a purpose in the national authorities to interfere in the affairs of Continental Europe. Kossuth's personal wants and the necessities of his family and friends were met by the sale of Hungarian bonds and by voluntary contributions; but no substantial aid was given to Hungary in its contest with Austria and Russia. In his many speeches Kossuth set forth his views upon national and international topics with freedom, and often with great wisdom. Said he on one occasion: "I take political economy for a science not exactly like mathematics. It is quite a practical thing, depending upon circumstances; but in certain proceedings a negative principle exists. In political economy it is not good for the people that a prohibitory system be adopted. Protection may sometimes be of service to a nation, but prohibition never." Thus did he qualify the claim of authors and students, who assert that political economy deserves rank among the sciences, whether exact or speculative, and thus did he recognize the protective theory as adapted to the condition of states while in the transition period in the development of the higher industries. It was a favorite thought with Kossuth that England would become republican, and that the United States and republican England could lead the world in civilization and in the work and duty of elevating the masses. His influence in Hungary had been due, in a large measure, to his active agency in the work of establishing associations for the advancement of agriculture, public education, commerce, and the mechanic arts. He deprecated the opposition of the Irish in America to any and every form of alliance with England, and he did not hesitate to condemn the demand of O'Connell for the repeal of the union between England and Ireland. Said he: "If I could contribute one line more to the future unity in action of the United States and England, I should more aid the Irish than by all exclamations against one or the other. With the United States and England in union, the Continent of Europe would be republican. Then, though England remained monarchist, Ireland would be more free than it is now."
