The Missouri decision made thus both for good and for evil--for good, surely, in that it produced clearer ideas upon the character of federal government, and preserved the East from an illiberal political policy toward the West; and in that it secured the great Northwest for free labor;--for evil, possibly, in that it estranged the two sections of the Union, and put a stop to any movement in the South for the gradual and {107} peaceable emancipation of the slaves, or for the substantial amelioration of their condition. It is not very likely, however, that any such movement would have proved successful, and it is, therefore, probable that what appears on the outside to have been an evil was in reality a good, in that it drove the disease in the body politic of the South onward toward the crisis, which must be passed in order that the permanent cure might be effected. {108} CHAPTER V.
