For the said plea involves the unwarrantable assumption that social agencies will continue to work only as they are now working; and will produce no results but those they seem likely to produce. It is the habit of this school of thinkers to make a limited human intelligence the measure of phenomena which it requires omniscience to grasp. {261} That which it does not see the way to, it does not believe will take place. Though society has, generation after generation, been growing to developments which none foresaw, yet there is no practical belief in unforeseen developments in the future. The parliamentary debates constitute an elaborate balancing of probabilities, having for data things as they are. Meanwhile every day adds new elements to things as they are, and seemingly improbable results constantly occur. Who, a few years ago, expected that a Leicester-square refugee would shortly become Emperor of the French? Who looked for free trade from a landlords’ ministry? Who dreamed that Irish over-population would spontaneously cure itself, as it is now doing? So far from social changes arising in likely ways, they usually arise in ways which, to common sense, appear unlikely. A barber’s shop was not a probable-looking place for the germination of the cotton manufacture. No one supposed that important agricultural improvements would come from a Leadenhall-street tradesman. A farmer would have been the last man thought of to bring to bear the screw propulsion of steam-ships. The invention of a new species of architecture we should have hoped from any one rather than a gardener. Yet while the most unexpected changes are daily wrought out in the strangest ways, legislation daily assumes that things will go just as human foresight thinks they will go. Though by the trite exclamation—“What would our forefathers have said!” there is a frequent acknowledgment of the fact that wonderful results have been achieved in modes wholly unforeseen, yet there seems no belief that this will be again. Would it not be wise to admit such a probability into our politics? May we not rationally infer that, as in the past so in the future?
