When we say two bodies 'touch', what we mean (without knowing it) is that both electromagnetic fields are interacting to avoid physical interpenetration and ... that happens well before subatomic particles touch!

Summary

This quote suggests that the concept of two bodies "touching" is a result of their electromagnetic fields interacting to prevent physical overlap or interpenetration. It implies that the notion of physical contact actually occurs at a subatomic level, before the particles making up the bodies come into direct contact with each other. In essence, the quote highlights the idea that what we perceive as touch is ultimately the result of energetic interactions between electromagnetically charged particles, rather than a direct contact between solid objects.
