At one time the benevolent affections embrace merely the family, soon the circle expanding includes first a class, then a nation, then a coalition of nations, then all humanity and finally, its influence is felt in the dealings of man with the animal world.

When men have appreciated the countless differences which the exercise of that judgment must necessarily produce, when they have estimated the intrinsic fallibility of their reason, and the degree in which it is distorted by the will, when, above all, they have acquired that love of truth which a constant appeal to private judgment at last produces, they will never dream that guilt can be associated with an honest conclusion, or that one class of arguments should be stifled by authority.
