 However, Pyrrho's own philosophy may have differed significantly in details from later Pyrrhonism.Most interpretations of the information on Pyrrho's philosophy suggest that he claimed that reality is inherently indeterminate, which, in the view of Pyrrhonism described by Sextus Empiricus, would be considered a negative dogmatic belief.A summary of Pyrrho's philosophy was preserved by Eusebius, quoting Aristocles, quoting Timon, in what is known as the "Aristocles passage."
