Yes, but our friend's apt analogy shows the danger of absorbing Plato's cave as the one thing you learned in Uni. If everything is a shadow on the wall then, of course, every type of study you just mentioned is merely another set of shadows. Nothing can be proven, and the coin of the realm is not to disprove anything but merely to signal your disbelief. Arguing with data for the power of reason against such a philosophy is pointless, as sincere as your response was (and I did appreciate it).
