Science ... has no consideration for ultimate purposes, any more than Nature has, but just as the latter occasionally achieves things of the greatest suitableness without intending to do so, so also true science, as the imitator of nature in ideas, will occasionally and in many ways further the usefulness and welfare of man,-but also without intending to do so.

It is, indeed, a fact that, in the midst of society and sociability every evil inclination has to place itself under such great restraint, don so many masks, lay itself so often on the procrustean bed of virtue, that one could well speak of a martyrdom of the evil man.
