It is the characteristic distinction of some men's work that they are resolute to take into just account all the elements and conditions of the matter with which they deal. They will not purchase simplicity at the expense of facts; they will not, by any act of arbitrary exclusion or unreal abstraction, give up even the most distant hope of some real attainment for the sake of securing a present appearance of completeness. They recognise and insist upon all the complexity of that at which they look; they may see many traits in it to which they can assign no definite place or meaning, but they will not ignore or disparage these; they will not forget them, even though for a while they may have to defer the closer study of them; they will dutifully bear them in mind, and carry them along through all their work; they will let them tell with full weight in qualifying, deferring, or precluding the formation of any theory about that of which these traits, trivial or important, explained or unexplained, are a genuine part. It is difficult to find a name for this rare and distinctive excellence. But it is that which more than any other quality gives permanence and fruitfulness to work: for even the fragmentary and loosely ordered outcome of such thought is wont to prove germinant and quickening as time goes on.
