Whether we are beside ourselves (eite ecesthmen). Second aorist active indicative of ecisthmi, old verb, here to stand out of oneself (intransitive) from ekstasiv, ecstasy, comes as in Mark 5:42. It is literary plural, for Paul is referring only to himself. See on II Corinthians 1:6 for eite—eite. It is a condition of the first class and Paul assumes as true the charge that he was crazy (if I was crazy) for the sake of argument. Festus made it later (Acts 26:24). He spoke with tongues (I Corinthians 14:18) and had visions (II Corinthians 12:1-6) which probably the Judaizers used against him. A like charge was made against Jesus (Mark 3:21). People often accuse those whom they dislike with being a bit off.
