"Conscience is the most sacred
of all property; other property depending in part on positive law, the
exercise of that being a natural and unalienable right. To guard a man's
house as his castle, to pay public and enforce private debts with the
most exact faith, can give no title to invade a man's conscience, which
is more sacred than his castle, or to withhold from it that debt of
protection for which the public faith is pledged by the very nature
and original conditions of the social pact."
