A. Εἰ with the Indicative 647 Εἰ with the present indicative, also with the perfect, imperfect, and aorist, presents the supposition simply, without implying anything as to its reality or probability; the tenses have the same force as in simple sentences (Simple or Logical Condition, present or past):

Εἴπερ γε Δᾱρείου ἐστὶ παῖς, οὐκ ἀμαχεῖ ταῦτʼ ἐγὼ λήψομαι if he is indeed a son of Dareios, I shall not take this without a battle. AN. I. 7, 9. θαυμάζοιμʼ ἂν εἰ οἶσθα I shοuld be surprised if you knοw. PR. 312 c. φήσουσι δή με σοφὸν εἶναι, εἰ καὶ μή εἰμι they will say of course that I am wise, althοugh (if in fact) I am not. The καί hints, without quite asserting, that the case is not merely assumed, but real. AP. 38 c.

Oὐ θαυμαστὸν δʼ εἰ τότε τς μορίᾱς ἐξέκοπτον it is not surprising if at that time they cut out the sacred olive-trees. L. 7, 7. εἰ κερδαίνειν ἐβούλου, τότʼ ἂν πλεῖστον ἔλαβες if you wished to make money, you would in that case have got most. The εἰ clause here is a simple condition; τότε is a conditional expression that resumes an earlier clause and stands for an unreal condition (649). L. 7, 20. εἰ ταῦτʼ αἰσθόμενος ἐγὼ διεκώλῡσα, ταῦτʼ ἐστὶ προδότην εἶναι τῶν φίλων; if I, perceiving this, prevented it, is that being a betrayer of ones friends? H. II. 3, 46.
