It may be said that a mind of this kind, the main character of which is a habit of diligent observation of Nature, presents nothing unusual, that all men have it more or less, and that we cannot make this habit or power a means of classification, or partition out an order of minds by what is a common possession of all minds. My contention is, however, that some minds possess this power and intentness of observation in quite an extraordinary degree, so that it really does separate them from other men. A parallel case may be found in music.
