Solzhenitsyn from his Templeton Address:
Our life consists not in the pursuit of material success but in the quest of worthy spiritual growth. Our entire earthly existence is but a transitional stage in the movement toward something higher, and we must not stumble and fall, nor must we linger fruitlessly on one rung of the ladder. Material laws alone do not explain our life or give it direction. The laws of physics and physiology will never reveal the indisputable manner in which The Creator constantly, day in and day out, participates in the life of each of us, unfailingly granting us the energy of existence; when this assistance leaves us, we die. In the life of our entire planet, the Divine Spirit moves with no less force: this we must grasp in our dark and terrible hour.
Instead of the ill-advised hopes of the last two centuries, which have reduced us to insignificance and brought us to the brink of nuclear and non-nuclear death, we can only reach with determination for the warm hand of God, which we have so rashly and self-confidently pushed away. If we did this our eyes could be opened to the errors of this unfortunate 20th century and our hands could be directed to set them right. There is nothing else to cling to, in the landslide: all the thinkers of the Enlightenment can give us nothing.
Our five continents are caught in a whirlwind. But it is during such trials that the highest gifts of the human spirit are manifested. If we perish and lose this world, the fault will be ours alone.
