Birmingham riots - a history of the town and its people
‘The present silent propogation of truth may even be compared to those causes in nature which lie dormant for a time, but which in proper circumstances act with the greatest violence. We are, as it were, laying gunpowder, grain by grain, under the old building of error and superstition, which a single spark may hereafter inflame, so as to produce an instantaneous explosion; in consequence of which, that edifice, the erection of which has been the work of ages, may be overturned in a moment, and so effectually, as that the same foundation can never be built upon again.’
