As an observer, when free from exaggeration, he has as good an eye as Balzac, but he is far more rarely thus free, for, in temperament, he is unequal and sometimes muddy. But then he has the heart and faith that Balzac wants, yet is less enslaved by emotion than Sand; therefore he has made more impression on his time and place than either. We refer now to his later works; though his earlier show much talent, yet his progress, both as a writer and thinker, has been so considerable that those of the last few years entirely eclipse his earlier essays. These latter works are the "Mysteries of Paris," "Matilda," and the "Wandering Jew," which is now in course of publication. In these, he has begun, and is continuing, a crusade against the evils of a corrupt civilization which are inflicting such woes and wrongs upon his contemporaries. Sue, however, does not merely assail, but would build up. His anatomy is not intended to injure the corpse, or, like that of Balzac, to entertain the intellectual merely. Earnestly he hopes to learn from it the remedies for disease and the conditions of health. Sue is a Socialist. He believes he sees the means by which the heart of mankind may be made to beat with one great hope, one love; and instinct with this thought, his tales of horror are not tragedies. This is the secret of the deep interest he has awakened in this country, that he shares a hope which is, half unconsciously to herself, stirring all her veins. It is not so warmly outspoken as in other lands, both because no such pervasive ills as yet call loudly for redress, and because private conservatism is here great, in proportion to the absence of authorized despotism. We are not disposed to quarrel with this; it is well for the value of new thoughts to be tested by a good deal of resistance. Opposition, if it does not preclude free discussion, is of use in educating men to know what they want. Only by intelligent men, exercised by thought and tried in virtue, can such measures as Sue proposes be carried out; and when such associates present themselves in sufficient numbers, we have no fear but the cause of association, in its grander forms, will have fair play in America.
