So acquire the habit of being present at this activity of the material and moral universe. Learn to look; compare what is before you with your familiar or secret ideas. Do not see in a town merely houses, but human life and history. Let a gallery or a museum show you something more than a collection of objects, let it show you schools of art and of life, conceptions of destiny and of nature, successive or varied tendencies of technique, of inspiration, of feeling. Let a workshop speak to you not only of iron and wood, but of man’s estate, of work, of ancient and modern social economy, of class relationships. Let travel tell you of mankind; let scenery remind you of the great laws of the world; let the stars speak to you of measureless duration; let the pebbles on your path be to you the residue of the formation of the earth; let the sigh of a family make you think of past generations; and let the least contact with your fellows throw light on the highest conception of man. If you cannot look thus, you will become, or be, a man of only commonplace mind. A thinker is like a filter, in which truths as they pass through leave their best substance behind.
A.G. Sertillanges, The Intellectual Life, (74)
I cannot think of a better summation of what my work as a teacher and scholar aims toward, nor can I recommend Sertillanges’s book highly enough. It is truly excellent and one of the books that most deeply shapes me.
