we now perceive, knew anything. It might be well if a greater number of effectual demonstrations existed among mankind; but while no such demonstrations exist, and while the evidence which completely convinces one man seems to another trifling and insufficient, let us recognise the plain position of inevitable doubt. Let us not be bigots with a doubt, and persecutors without a creed. We are beginning to bee this, and we are railed at for so beginning. But it is a great benefit, and it is to the incessant prevalence of detective discussion that our doubts are due; and much of that discussion is due to the long existence of a government requiring constant debates, written and oral. This is one of the unrecognised benefits of free government, one of the modes in which it counteracts the excessive inherited impulses of humanity. There is another also for which it does the same, but which I can only touch delicately, and which at first sight will seem ridiculous. The most successful races, other things being equal, are those which multiply the fastest. In the conflicts of mankind numbers have ever been a great power. The most numerous group has always had an advantage over the less numerous, and the fastest breeding group has always tended to be the most numerous. In consequence, human nature has descended into a comparatively uncontentious civilisation, with a desire far in excess of what is needed; with a 'felt want,' as political economists would say, altogether greater than the 'real want.' A walk in London is all which is necessary to establish this. 'The great sin of great cities' is one vast evil consequent upon it. And who is to reckon up how much these words mean? How many spoiled lives, how many broken hearts, how many wasted bodies, how many ruined minds, how much misery pretending to be gay, how much gaiety feeling itself to be miserable, how much after mental pain, how much eating and transmitted disease. And in the moral part of the world, how many minds are racked by incessant anxiety, how many thoughtful imaginations which might have left something to mankind are debased to mean cares, how much every successive generation sacrifices to the next, how little does any of them make of itself in comparison with what might be. And how many Irelands have there been in the world where men would have been contented and happy if they had only been fewer; how many more Irelands would there have been if the intrusive numbers had not been kept down by infanticide and vice and misery. How painful is the conclusion that it is dubious whether all the machines and inventions of mankind 'have yet lightened the day's labour of a human being.' They have enabled more people to exist, but these people work just as hard and are just as mean and miserable as the elder and the fewer.
