[The aorist] ai)sqe/sqai differs from [the present] ai)sqa/nesqai. For ai)sqe/sqai [is used] in reference to knowing something accurately, but ai)sqa/nesqai [is used] in reference to conjecturing something. And as regards ai)sqa/nesqai, Antiphon in Proems [says]: "I wrote this indictment because great injustice was done to me by this man, by Zeus, but I perceived that you and the other citizens have suffered even greater injustice."[1] But ai)sqa/nesqai [is used] in reference to suspicion and not in reference to sure knowledge. Lysias in the [speech] In Reply to Alcibiades says: "I suppose indeed that you perceive this also, that Archibiades was not seeking to gain anything else but was laying claim to my possessions."[2] But they have used this [verb] also in reference to knowledge. Isaeus [says]: "Of this testimony you who are judging know some parts for yourselves (that the child recovered), perceiving from the witnesses who saw; other parts you have learned from hearing."[3]
