All censorships exist to prevent anyone from challenging current conceptions and existing institutions. All progress is initiated by challenging current conceptions, and executed by supplanting existing institutions. Consequently, the first condition of progress is the removal of censorship.
The population of the world is a conditional population; these are not the best, but the best that could live in the existing state of soils, gases, animals, and morals: the best that could yet live; there shall be a better, please God.
Our words must be judged by our deeds; and in striving for a lofty ideal we must use practical methods; and if we cannot attain all at one leap, we must advance towards it step by step, reasonably content so long as we do actually make some progress in the right direction.
One atom in this universe cannot move without dragging the whole world along with it. There cannot be any progress without the whole world following in the wake, and it is becoming every day dearer that the solution of any problem can never be attained on racial, or national, or narrow grounds.
