Doubtless many will reply that they can more easily conceive ten millions of special creations to have taken place, than they can conceive that ten millions of varieties have arisen by successive modifications. All such, however, will find, on inquiry, that they are under an illusion. This is one of the many cases in which men do not really believe, but rather _believe they believe_. It is not that they can truly conceive ten millions of special creations to have taken place, but that they _think they can do so_. Careful introspection will show them that they have never yet realized to themselves the creation of even _one_ species. If they have formed a definite conception of the process, let them tell us how a new species is constructed, and how it makes its appearance. Is it thrown down from the clouds? or must we hold to the notion that it struggles up out of the ground? Do its limbs and viscera rush together from all the points of the compass? or must we receive the old Hebrew idea, that God takes clay and moulds a new creature? If they say that a new creature is produced in none of these modes, which are too absurd to be believed, then they are required to describe the mode in which a new creature _may_ be produced--a mode which does _not_ seem absurd; and such a mode they will find that they neither have conceived nor can conceive. Should the believers in special creations consider it unfair thus to call upon them to describe how special creations take place, I reply that this is far less than they demand from the supporters of the Development Hypothesis. They are merely asked to point out a _conceivable_ mode. On the other hand, they ask, not simply for a _conceivable_ mode, but for the _actual_ mode. They do not say--Show us how this _may_ take place; but they say--Show us how this _does_ take place. So far from its being unreasonable to put the above question, it would be reasonable to ask not only for a _possible_ mode of special creation, but for an _ascertained_ mode; seeing that this is no greater a demand than they make upon their opponents.
