INTRODUCTION

Those very remarkable technical inventions which are the boast of the men of our generation, though they spring from human intelligence and industry, are nevertheless the gifts of God, Our Creator, from Whom all good gifts proceed: "for He has not only brought forth creatures, but sustains and fosters them once created"¹

Of these inventions, some increase and multiply the strength and power of men; others improve their conditions of life; while others - and these particularly concern the mind - reach the mass of the people themselves, either directly or through the pictures and sounds they produce, and convey to them in a form easy to understand, the news, thoughts and usages of every nation, and by these means provide, as it were, food for the mind especially during the hours of rest and recreation.

With regard to this last type of invention, in our own age the greatest impetus has been received by the arts connected with Motion Pictures, Radio and Television.
