Of all the errors which can possibly be committed to the education of youth, that of sending them to Europe is the most fatal. I see [clearly] that no American should come to Europe under 30 years of age.

Both of our political parties, at least the honest portion of them, agree conscientiously in the same object: the public good; but they differ essentially in what they deem the means of promoting that good. One side believes it best done by one composition of the governing powers, the other by a different one. One fears most the ignorance of the people; the other the selfishness of rulers independent of them. Which is right, time and experience will prove.

How to check these unconstitutional invasions of rights by the Federal judiciary? Not by impeachment in the first instance, but by a strong protestation of both houses of Congress that such and such doctrines advanced by the Supreme Court are contrary to the Constitution; and if afterwards they relapse into the same heresies, impeach and set the whole adrift.
