Where the principle of difference [between political parties] is as substantial and as strongly pronounced as between the republicans and the monocrats of our country, I hold it as honorable to take a firm and decided part and as immoral to pursue a middle line, as between the parties of honest men and rogues, into which every country is divided.

Reason and free inquiry are the only effective agents against error. Give a loose to them, they will support the true religion by bringing every false one to their tribunal, to the test of their investigation. They are the natural enemies of error and error only. Had not the Roman government permitted free inquiry, Christianity could never have been introduced. Had not free inquiry been indulged at the era of the Reformation, the corruption of Christianity could not have been purged away.

Nothing can now be believed that is seen in a newspaper.

The executive, in our government is not the sole, it is scarcely the principle, object of my jealousy. The tyranny of the legislature is the most formidable dread at present and will be for many years. That of the executive will come in its turn, but it will be at a remote period.

In a government bottomed on the will of all, the... liberty of every individual citizen becomes interesting to all.

If science produces no better fruits than tyranny... I would rather wish our country to be ignorant, honest and estimable as our neighbouring savages are.
