to read a different work on the same subject while the first is still
fresh in your mind. The sameness of the facts gives the additional force
of a double impression; and the variation in the mode of stating them,
always more striking when the books are the respective works of a man
and of a woman, adds the force of a trebled impression, stronger than
the two others, because there is in it more of the exercise of the
intellect, that is, on the supposition that, in accordance with the
foregoing rules, you should think over each respective statement until
you have reconciled them together by ascertaining the cause of the
variation.

I shall now proceed to those lighter branches of literature which are
equally necessary with the preceding, and which will supply you with the
current coin of the day,--very necessary for ordinary intercourse,
though, in point of real value, far inferior to the bank-stock of
philosophic and scientific knowledge which it is to be your chief object
to acquire. History is the branch of lighter literature to which your
attention should be specially directed; it provides you with
illustrations for all philosophy, with excitements to heroism and
elevation of character, stronger perhaps than any mere theory can ever
afford. The simplest story, the most objective style of narrative, will

unnecessary word throughout the whole. If you do not find getting by
heart an insuperable difficulty, you will do well to commit every line
to memory. Half a page a day of the small edition would soon lay up for
