Thus to him, to this school-boy under the bending dome of day, is
suggested that he and it proceed from one Root; one is leaf and one is
flower; relation, sympathy, stirring in every vein. And what is that
root? Is not that the soul of his soul?--A thought too bold?--A dream

more earthly natures,--when he has learned to worship the soul, and to
see that the natural philosophy that now is, is only the first
gropings of its gigantic hand,--he shall look forward to an
ever-expanding knowledge as to a becoming creator.[13] He shall see
that nature is the opposite of the soul, answering to it part for

own mind. Its laws are the laws of his own mind. Nature then becomes
to him the measure of his attainments. So much of nature as he is
ignorant of, so much of his own mind does he not yet possess. And, in

influence of the past, and perhaps we shall get at the truth,--learn
the amount of this influence more conveniently,--by considering their
value alone.

The theory of books is noble. The scholar of the first age received
into him the world around; brooded thereon; gave it the new
