Or ought we to invokeu la loi des grands nombres," and say that the roots areas often sensible as insensible? It would be absurd.There is obviously a reason why they are sensible, areason why they are not, and it is these reasons we are todiscover.A great surgeon performs an operation many timeshe then gives a tabular statement of the cases whichhave been fatal and the cases which have been successful,and statistically concludes that themortality of this operationis two in five. What will this tell us respectingthe certainty of the next case? "We can not knowwhether it will be one of the two or one of the three.We ought to know what are the conditions which willrange it infallibly under one or the other head.Insteadof an idle enumeration, we should make a fruitful studyof each special case, and discover, if possible, the causewhich renders the operation fatal. The same reasoningapplies to curative remedies. A certain remedy has intwenty instances been followed by a cure ; in seven instancesno cure has been effected. You will say, perhaps,that there is twenty to seven in favor of success.the least.~Not inYou do not know how many of those twentypatients would have recovered had there been anotherremedy tried, or no remedy at all; you do not knowwhat was the precise action of the remedy, what changesiteffected in the organism, what its effects will be on theorganism now about to be submitted to it.
