Wrong Conclusions From Usefulness.—When we have demonstrated the highest utility of a thing, we have nevertheless made no progress towards an explanation of its origin; in other words, we can never explain, by mere utility, the necessity of existence. But precisely the contrary opinion has been maintained up to the present time, even in the domain of the most exact science. In astronomy, for example, have we not heard it stated that the (supposed) usefulness of the system of satellites—(replacing the light which is diminished in intensity by the greater distance of the sun, in order that the inhabitants of the various celestial bodies should not want for light)—was the final object of this system and explained its origin?
