How does a local sign function for touch, according to Lotze?

Lotze's concept of local signs involves the idea that sensation arises from specific areas of the body and corresponds to distinct touch locations. Specifically, local signs serve as cues that capture the intensity and pattern of touch sensations at various points on the skin. This means that when we touch something, we perceive not just a general sensation, but rather a specific experience that correlates with the exact location of that touch. Thus, the perception of touch is framed by the unique intensity patterns generated at different spots on the skin, allowing for the differentiation of sensations as informed by where they occur. This concept lays the groundwork for understanding sensory localization in the context of touch.
