Temporary delusions, prejudices, excitements, and objects have irresistible influence in mere questions of policy. And the policy of one age may ill suit the wishes or the policy of another.

It should be, so far at least as human infirmity will allow, not dependent upon the passions or parties of particular times, but the same yesterday, to-day, and for ever.
