Prayer is intended to increase the devotion of the individual, but if the individual himself prays he requires no formula; he pours himself forth much more naturally in self-chosen and connected thoughts before God, and scarcely requires words at all. Real inward devotion knows no prayer but that arising from the depths of its own feelings.
Wilhelm von HumboldtWherever the citizen becomes indifferent to his fellows, so will the husband be to his wife, and the father of a family toward the members of his household.
Wilhelm von HumboldtThe sensual and spiritual are linked together by a mysterious bond, sensed by our emotions, though hidden from our eyes. To this double nature of the visible and invisible world - to the profound longing for the latter, coupled with the feeling of the sweet necessity for the former, we owe all sound and logical systems of philosophy, truly based on the immutable principles of our nature, just as from the same source arise the most senseless enthusiasms.
