Capítulo 3. Chapter III.—Of The Nomenclature of Scepticism
[1.3.7] The Sceptic School, then, is also called ‟Zetetic” from its activity in investigation and inquiry, and ‟Ephectic” or Suspensive from the state of mind produced in the inquirer after his search, and ‟Aporetic” or Dubitative either from its habit of doubting and seeking, as some say, or from its indecision as regards assent and denial, and ‟Pyrrhonian” from the fact that Pyrrho[5] appears to us to have applied himself to Scepticism more thoroughly and more conspicuously than his predecessors.
