We must know. We will know.

The after-dinner talk has by now become a tradition of this Conference series on Quark Confinement and the Hadron Spectrum. On this occasion, I have tried to combine a free-style and (hopefully) amusing presentation with deep questions of physics especially connected with the dynamics of strong interaction. To this end some masterpieces of classical music (by Beethoven, Mozart, Dvorak, Stravinsky ...) and pop music (by Bob Dylan, Eric Clapton) were employed to illustrate certain aspects of physics. By no means was this presentation (neither this paper) intended as a comprehensive review of the different topics examined during the Conference, but rather as a call for further thinking on the sinergy of different branches of physics and the excitement of foreseen discoveries in a not too distant future.
