The development of exact natural knowledge in all its vast range, from
physics to history and criticism, is the consequence of the working out,
in this province, of the resolution to "take nothing for truth without
clear knowledge that it is such"; to consider all beliefs open to
criticism; to regard the value of authority as neither greater nor less
than as much as it can prove itself to be worth. The modern spirit is
not the spirit "which always denies," delighting only in destruction;
still less is it that which builds castles in the air rather than not
construct; it is that spirit which works and will work "without haste
and without rest," gathering harvest after harvest of truth into its
barns and devouring error with unquenchable fire.
