I never considered a difference of opinion in politics, in religion, in philosophy, as cause for withdrawing from a friend.

Indeed, we need not look back half a century to times which many now living remember well, and see the wonderful advances in the sciences and arts which have been made within that period. Some of these have rendered the elements themselves subservient to the purposes of man, have harnessed them to the yoke of his labors and effected the great blessings of moderating his own, of accomplishing what was beyond his feeble force, and extending the comforts of life to a much enlarged circle, to those who had before known its necessaries only.

The way to silence religious disputes is to take no notice of them.

Difference of opinion leads to enquiry, and enquiry to truth; and I am sure...we both value too much the freedom of opinion sanctioned by our Constitution, not to cherish its exercise even where in opposition to ourselves.

No experiment can be more interesting than that we are now trying, and which we trust will end in establishing the fact, that man may be governed by reason and truth. Our first object should therefore be, to leave open to him all the avenues to truth. The most effectual hitherto found, is the freedom of the press. It is, therefore, the first shut up by those who fear the investigation of their actions.

We have no right to prejudice another in his civil enjoyments because he is of another church.

It is part of the American character to consider nothing as desperate.
