This writing is intended to serve as answer to numerous communications which for lack of opportunity have not been properly acknowledged. It presents, briefly, and without any attempt at systematic development, a well-known point of view, one which, though often ignored, helps vastly in the search for truth. It is really an attempt to answer the questions, What is science? How does the Church view science? and is therefore a general introduction to the more picturesque and perhaps more interesting analyses of current scientific doctrine. The youth of our day, in their approach to knowledge, are thinking for themselves. For that let us be grateful. And may they think straight, so that truth may not pass them by unrecognized!
