Love can make us fiends as well as angels.

Do today's duty, fight to-day's temptation; and do not weaken and distract yourself by looking forward to things which you cannot see, and could not understand if you saw them.

Do what thou dost as if the earth were heaven, and thy last day the day of judgment.

You must not say that this cannot be, or that that is contrary to nature. You do not know what Nature is, or what she can do; and nobody knows; not even Sir Roderick Murchison, or Professor Huxley, or Mr. Darwin, or Professor Faraday, or Mr. Grove, or any other of the great men whom good boys are taught to respect. They are very wise men; and you must listen respectfully to all they say: but even if they should say, which I am sure they never would, 'That cannot exist. That is contrary to nature,' you must wait a little, and see; for perhaps even they may be wrong.

Madame Nature allows no dangerous classes, in the modern sense. She has, doubtless for some wise reason, no mercy for the weak. She rewards each organism according to its works; and if anything grows too weak or stupid to take care of itself, she gives it its due deserts by letting it die and disappear.

We ought to reverence books; to look on them as useful and mighty things. If they are good and true, whether they are about religion, politics, farming, trade, law, or medicine, they are the message of Christ, the maker of all things - the teacher of all truth.

Except a living man there is nothing more wonderful than a book! A message from the dead - from human souls we never saw, who lived, perhaps, thousands of miles away. And yet these, in those little sheets of paper, speak to us, arouse us, terrify us, comfort us, open their hearts to us as brothers.
