Korihor is an infamous account found in the Book of Mormon, of a man who’s teachings were counter to God’s truth, although subtle and very appealing. Because of this, he had much success in his day. The scriptures provide us with this account to enable us to recognize similar teachings in our day to avoid the deception. Korihor’s teaching that “ye cannot know of things which ye do not see” is the philosophy that all ideas and knowledge are derived from and can be tested by experience, that we only know things that we experience through our senses: sight, smell, touch, hearing, or taste. Since spiritual experiences involving revelation from God rarely pass through the senses of sight, smell, touch, hearing, or taste, those who hold to Korihor’s philosophy count them as meaningless.
