Most men are followers, and implicitly rely upon the judgment of others. They mistake solemnity for wisdom, and regard a grave countenance as the title page and Preface to a most learned volume. So they are easily imposed upon by forms, strange garments, and solemn ceremonies. And when the teaching of parents, the customs of neighbors, and the general tongue approve and justify a belief or creed, no matter how absurd, it is hard even for the strongest to hold the citadel of his soul. In each country, in defence of each religion, the same arguments would be urged.
