  We analyze data on deep inelastic scattering of electrons from the proton
using ideas from standard many-body theory involving {\em bound} constituents
subject to {\em interactions}. This leads us to expect, at large three-momentum
transfer ${\bf{q}}$, scaling in terms of the variable $\tilde{y}=\nu-{\bf
|q|}$. The response at constant ${\bf |q|}$ scales well in this variable.
Interaction effects are manifestly displayed in this approach. They are
illustrated in two examples.
