Flying. Whatever any other organism has been able to do man should surely be able to do also, though he may go a different way about it.
Samuel ButlerNature. As the word is now commonly used it excludes nature's most interesting productions-the works of man. Nature is usually taken to mean mountains, rivers, clouds and undomesticated animals and plants. I am not indifferent to this half of nature, but it interests me much less than the other half.
Samuel Butler
