“Okay, you were probably taught there are five senses," he said. "We see, hear, touch, smell and taste. But how do we know those are the only five? What are the senses that we don't have? What are we failing to perceive?”

The Living Reminder: Service and Prayer in Memory of Jesus Christ (1977)
Context: When we walk in the Lord's presence, everything we see, hear, touch, or taste reminds us of Him. This is what is meant by a prayerful life. It is not a life in which we say many prayers but a life in which nothing, absolutely nothing, is done, said, or understood independently of Him who is the origin and purpose of our existence.

The Tragic Sense of Life (1913), II : The Starting-Point
Context: Knowledge is employed in the service of the necessity of life and primarily in the service of the instinct of personal preservation. The necessity and this instinct have created in man the organs of knowledge and given them such capacity as they possess. Man sees, hears, touches, tastes and smells that which it is necessary for him to see, hear, touch, taste and smell in order to preserve his life. The decay or loss of any of these senses increases the risks with which his life is environed, and if it increases them less in the state of society in which we are actually living, the reason is that some see, hear, touch, taste and smell for others. A blind man, by himself and without a guide, could not live long. Society is an additional sense; it is the true common sense.

Thoughts in Solitude (1956)
Context: We must suffer. Our five sense are dulled by inordinate pleasure. Penance makes them keen, gives them back their natural vitality, and more. Penance clears the eye of conscience and of reason. It helps think clearly, judge sanely. It strengthens the action of our will.
