Curiosity consists of trying to know everything without order, without aim, without distinguishing whether it is needful or not. It is only necessary that one should preserve a measure and order in exercising the senses, and direct them only to what is needful and to awareness of what is needful—then there will be no food for curiosity.
—St. Theophan the Recluse, The Path to Salvation: A Manual of Spiritual Transformation
