29. The Mystery of Human Temperaments
These are insights that can affect every fiber of the individual human being, that can govern every single action in life. In this way — and this was particularly evident in this consideration of the intimate peculiarities of human beings, of temperaments — spiritual science becomes a guide to the true art of living. This is how the most beautiful thing is kindled between human beings, when we look into the face of another human being and not only seek to fathom the mystery, but also understand how to live: to allow love to flow from individuality to individuality. Spiritual science does not need theoretical proof; life itself provides the proof. The spiritual scientist knows that one can raise arguments “for” and “against” everything. The true evidence is that which life provides, and life can show us at every turn the truth of what we think when we look at human beings through spiritual scientific insight, for this insight consists of a harmonious, life-filled recognition that penetrates into the deepest mysteries of life.
