“If technical progress is not matched by corresponding progress in man's ethical formation, in man's inner growth, then it is not progress at all, but a threat for man and for the world.”

Context: The progressive development of man is vitally dependent on invention. It is the most important product of his creative brain. Its ultimate purpose is the complete mastery of mind over the material world, the harnessing of the forces of nature to human needs. This is the difficult task of the inventor who is often misunderstood and unrewarded. But he finds ample compensation in the pleasing exercises of his powers and in the knowledge of being one of that exceptionally privileged class without whom the race would have long ago perished in the bitter struggle against pitiless elements. Speaking for myself, I have already had more than my full measure of this exquisite enjoyment; so much, that for many years my life was little short of continuous rapture.

More Worlds Than One: The Creed of the Philosopher and the Hope of the Christian (1856), "Religious Difficulties", p. 157-158
Context: The history of the human species is the history of a variety of races in every stage of civilization and barbarism, and the great majority of which have neither an intellectual, nor a moral, nor a religious progressive history. Progression has not been the character of the history of man. Without alluding to his primeval fall from his high estate, we have only to cast our eyes over the globe, and look at the intellectual, moral, and religious catastrophes which it presents to us, — at ages of light and darkness, — at alternations of progress and decline, — at the highest civilization sinking into the lowest barbarism. Mark those eastern lands, now involved in darkness, from which the beams of knowledge first radiated on mankind. Study the extinction of morality in many regions of the earth where its great lessons were first taught by our Saviour and His apostles; and above all, mark the total suppression of the Christian faith in European communities, where it has been displaced by a religion whose doctrines were preached by conquest, and whose decalogue was dictated by the sword.
