National changes, the movements and progress of the human race, as a

whole and in its parts, are obedient, likewise, to law; and are,
therefore, logical in their character, though generally lacking in
precision of connection and order of succession
National changes, the movements and progress of the human race, as a
whole and in its parts, are obedient, likewise, to law; and are,
therefore, logical in their character, though generally lacking in
precision of connection and order of succession. Or it may be, rather,
that we lack power to trace the connection between events that depend in
part, at least, upon the prejudices, passions, vices, and weaknesses, of
men. The development of the logic of human affairs waits for a
philosopher who shall study and comprehend the living millions of our
race, as the philosophers now study and comprehend the subjects of
physical science. We have no guaranty that this can ever be done. As
mind is above matter, the mental philosopher enters upon the most varied
and difficult field of labor.
