Now, in answer to this objection, I have only to say that no one can have a more lively appreciation than myself of the supreme importance of experimental or historical veri fication, in all cases where the possibility of such verification is attainable. But in cases where such verification is not attainable, what are we to do ? We may clearly do either of two things. We may either neglect to investigate the sub ject at all, or we may Jo our best to investigate it by employ ing the only means of .investigation which are at our disposal. Of these two courses there can be no doubt which is the one that the scientific spirit prompts. The true scientific spirit desires to examine everything, and if in any case it is refused the best class of instruments wherewith to conduct the examination, it will adopt the next best that are available. In such cases science clearly cannot be forwarded by neglect ing to use these instruments, while her cause may be greatly advanced by using them with care. This is proved by the fict that, in the science of psychology, nearly all the con siderable advances which have been made, have been made, not by experiment, but by observing mental phenomena and reasoning from these phenomena deductively. In such cases, therefore, the true scientific spirit prompts us, not to throw away deductive reasoning where it is so frequently the onlyinstrument available, but rather to cany it with us, and to use it as not abusing it.
