All these works are rich in materials for forming intelligent Opinions, even where
we are unable to agree with those put forth by the author. Much may be learned from
.Ihem in departments in which our common Educational system is very deficient. The
lctivc citizen may derive from them accurate systematized information concerning his
highest duties to society, and the principles on which they are based. He may gain
clearer notions of the value and bearing of evidence, and be better able to distinguish
between facts and inferences. He may find common things suggestive of wiser thought
-nay, we will venture to say of truer emotion—than before. By giving us fuller reali-
utions of liberty and justice his writings will tend to increase our self-reliance in the
treat emergency of ci vilization to which we have been summoned.— Atlantic .Honthl-u
