Texture
Touch is perhaps the most intimate sense. Hearing, sight, and smell can all detect distant sources, but touch requires actual contact. However, we can, in a way, touch things at a distance.  When light strikes an object, its actual texture gives rise to complex patterns of value and color. Our eyes can detect these patterns that are then interpreted by the brain to predict what a surface might feel like. Whether they are actual or simulated, textures can have powerful associative qualities often adding a strong sense of presence, weight, and history to artworks.
