Abstract

The reductio ad absurdum has been elected by Zeno as the only method permitting to descry the true reality, invisible both to the senses and to the common way of thinking. Showing some continuity with the previous philosophers, not only in the search for a procedure in order to speculation to advance, but also on the same route departing from what is nearer, more acquainted and particular (visible) toward what is less acquainted, more distant and universal (invisible), to say it with aristotelic words, Zeno made use of aporetic arguments as the only possible way to catch a glimpse of the ‘domain of Being’. This, in fact, is invisible not only to our senses, but also to our ordinary reasoning. Therefore, just the ‘way of not-being’, the only one that could be walked after Parmenides, as Wolff says, allows us to have an insight of what is ‘really invisible’. So invisible that it is unreachable also to thought.
