A sensuist is someone who delights in sensory experience. It is not the same as a sensualist, one who is gratified by satisfying his or her sexual appetites.
Diane Ackerman, in her best-selling book, A Natural History of the Senses,
writes of Hellen Keller as one of the greatest sensuists of all time.
Deaf, blind and mute, "her remaining senses were so finely attuned that
when she put her hands on the radio to enjoy music, she could tell the
difference between the cornets and the strings. She listened to
colorful, downhome stories of life surging down the Mississippi from her
friend Mark Twain. She wrote at length about the whelm of life's
aromas, tastes, touches, feelings, which she explored with the
voluptuousness of a courtesan. Despite her handicaps, she was more
robustly alive than many people of her generation."
