SCIENCE AND FAITH. 335 
at the same time, on the other hand, once more to set forth 
the convincing arguments which bear testimony to the 
truth of the theory of development. 
The objections which are raised to the doctrine of descent 
may be divided into two large groups: objections of faith 
and objections of reason. The objections of the first group 
originate in the infinitely varied forms of faith held by 
human individuals, and need not here be taken into con- 
sideration at all. For, as I have already remarked at the 
beginning of this book, science, as an objective result of 
sensuous experience, and of the striving of human reason 
after knowledge, has nothing whatever to do with the sub-

as the direct inspirations or revelations of the Creator, and 
then believed in by the dependent multitude. This belief, 
very different in different nations, only begins, as is well 
known, where science ends. Natural Science believes, 
according to the maxim of Frederick the Great, “that 
every one may go to heaven in his own fashion,” and only 
necessarily enters into conflict with particular forms of 
faith where they appear to set a limit to free inquiry 
and a goal to human knowledge, beyond which we are 
not to venture. Now this is certainly the case here in 
the highest degree, for the Theory of Development applies 
itself to the solution of the greatest of scientific problems— 
that of the creation, the coming into existence of things ; 
more especially the origin of organic forms, and of man at 
their head. It is here certainly the right as well as the 
sacred duty of free inquiry, to fear no human authority, 
and courageously to raise the veil from the image of the 
Creator, unconcerned as to what natural truth may lie con-
