QCD correlation functions and instantons

QCD point-to-point correlation functions at distances .2-1 fm are very different for different channels, and they tell us a lot about inter-quark interactions. Recent studies based on experimental data, 'instanton liquid' approach and lattice measurements are reviewed. Agreement between all of them show that instanton-induced forces dominate the light quark physics, and new findings by Negele et al, that {\it hadrons survive 'cooling'}, make this statement obvious. We also argue that {\it chiral symmetery restoration} is due to breaking of the 'instanton liquid' into {\it polarized} 'instanton molecules'. % For Lattice-93 proceedings, figures and % hard copies available at request, sorry.
