26. [...] there is nothing more difficult to take in hand,

    more perilous to conduct, or more uncertain in its success, than to take the lead in the introduction of a new order of things.

    done well under the old conditions, and lukewarm defenders in those who may do well under the new.

28. This coolness arises [...] partly from the incredulity of men,

    who do not readily believe in new things until they have had a long experience of them.
