although Plato (in the Parmenides), the Megarics, Pyrrho, and the New-Academy, showed by examples (in the manner which was afterwards adopted by Sextus Empiricus) how syllogisms and concepts were also sometimes misleading, and indeed produced paralogisms and sophisms which arise much more easily and are far harder to explain than the illusion of sense-perception.
nahiz eta Platonek ('Parmenides'en), megarikoek, Pirronek eta neoakademikoek adibideen bitartez (gerora Sexto Enpirikok egingo zuen eran) erakutsi zuten silogismoek eta kontzeptuek ere errorera gidatzen dutela, are paralogismoak eta sofismak sortu ere egiten dituztela, sentsuzkotasun-begiespenean begitazioa baino askozaz errezago sortzen direnak, eta desegiten askozaz zailagoak direnak.
