The paper examines the doctrine of "Rechtsgefühl" as developed by the famous Pandectist and legal empiricist Rudolf von Jhering. The iridescent concept of Rechtsgefühl is discussed extensively and impressively in the literature, but Jhering's key contribution usually receives only cursory mention. This paper is intended to show the great significance of Jhering's Rechtsgefühl, particularly its role in his lecture The Struggle for Law. Rechtsgefühl, as Jhering conceives it, combines a practical consideration of individual cases, a reflection of the purposes of law and the experience of the observer. It is the essence of what Jhering understands by living legal doctrine and the progress of law.
