9/8j In the slip box is a slip containing the argument that refutes the claims on all the other slips.

But this slip disappears as soon as you open the slip box.

Ie he assumes a different number, disguises himself and then cannot be found.

A joker.

"Eclecticism may be defined as the practice of choosing apparently irreconcilable doctrines from antagonistic schools and constructing therefrom a composite philosophic system in harmony with the convictions of the eclectic himself. Eclecticism can scarcely be considered philosophically or logically sound, for as individual schools arrive at their conclusions by different methods of reasoning, so the philosophic product of fragments from these schools must necessarily be built upon the foundation of conflicting premises. Eclecticism, accordingly, has been designated the layman's cult. In the Roman Empire little thought was devoted to philosophic theory; consequently most of its thinkers were of the eclectic type. Cicero is the outstanding example of early Eclecticism, for his writings are a veritable potpourri of invaluable fragments from earlier schools of thought. Eclecticism appears to have had its inception at the moment when men first doubted the possibility of discovering ultimate truth. Observing all so-called knowledge to be mere opinion at best, the less studious furthermore concluded that the wiser course to pursue was to accept that which appeared to be the most reasonable of the teachings of any school or individual. From this practice, however, arose a pseudo-broadmindedness devoid of the element of preciseness found in true logic and philosophy."
