To enjoy life, we must touch much of it lightly. ~ French writer Voltaire
Touch is the longest single entry in unabridged dictionaries of many languages. The associations are incredibly rich, if a bit touchy. Feeling comes from being touched emotionally. Stay in touch.
Of all the senses, touch produces the most intense memories. Touch makes the world seem real like no other sense.
Humans can compensate, at least somewhat, for loss of vision, hearing, or smell/taste. But blocking tactile sensation produces a profound, unshakable disorientation that quickly leads to psychosis. Touch defines our sense of reality.
Learning through touch is instinctual; as important as vision for retaining information. Even newborns can recognize objects by touch alone. ~ American cognitive scientists Derek Cabrera & Laura Colosi
