There is thus a scientific conception of the aim of science; on the other hand, there is an ethical conception of it. The former points in the direction of the indefinite extension of knowledge which never embraces a totality of the knowable, never reaches a limit, even in idea. The latter points to the _infinite_, not to the _indefinite_, sets up an ideal of the infinite as the goal, takes the man out of the flux, centralizes his individuality into a personality by relating him to the infinite, not as the mere spectator and scribe of nature, but through his action or other potential spiritual beings like himself. The scientist, in brief, like every one else, becomes a personality by eliciting the potential spiritual nature in other human beings. But be it noted that he is to perform this task _as a scientist_. His particular occupation is to be the means of producing a particular spiritual result in others as well as in himself, and by this means his occupation is to be converted into a vocation. How? Through partial success and frustration. Partial success in the case of a scientist means for one thing, increased mental grasp, the power to hold before the mind ever more and more complex relations,—a faculty supremely serviceable in mastering complexities of relation in the economic, in the political spheres, in the sphere of international intercourse, in the sphere of the social relations in general, and wherever the ethical principle has to be applied. The scientific occupation trains powers which are to be exercised so as to illuminate obscurities in the ethical field.
