Dynamical chiral symmetry breaking and its connection with the generation of
hadron masses has historically been viewed as a vacuum phenomenon. We argue
that confinement makes such a position untenable. If quark-hadron duality is a
reality in QCD, then condensates, those quantities that were commonly viewed as
constant empirical mass-scales that fill all spacetime, are instead wholly
contained within hadrons; viz., they are a property of hadrons themselves and
expressed, e.g., in their Bethe-Salpeter or light-front wave functions. We
explain that this paradigm is consistent with empirical evidence, and
incidentally expose misconceptions in a recent Comment.
