“A barrage of words does not make the soul happy, but a good life gladdens the mind and a pure conscience generates a bountiful confidence in God.”

“Conscience is thus explained only as the voice of God in the soul.”

“Humanity cannot lift itself by its own bootstraps; there is no such thing as spontaneous generation; life does not come from crystals; poetry does not come from donkeys; international peace does not come from wars; social justice does not come from selfishness. With all our knowledge of chemistry we cannot make a human life in our laboratories because we lack the unifying, vivifying principal of a soul which comes only from God. Life is not a push from below; it is a gift from above. It is not the result of the necessary ascent of man but the loving descent of God.”

“A man who has no conscience, no goodness, does not suffer.”

“Oh! To live alone, always alone, in the midst of the crowd that surrounds me, without a word of love ever coming to gladden my soul, without a friendly hand reaching out to me!”

“The ultimate test of man's conscience may be his willingness to sacrifice something today for future generations whose words of thanks will not be heard.”
