I recently discovered some interesting observations concerning the interpretation of the aorist and perfect tenses. Among linguists these observations are well-known. But I don’t recall any discussion of them within our forums.
Yet now and then arises here the question, “What is the semantic difference between the aorist and the perfect?” We all (should) know the (more or less) textbook answer: the aorist discloses the action of the verb simply as occurring, “an action pure and simple” (Chantraine); the perfect describes a persistent state which follows from some prior action.
How then do these two sentences, one aorist (simple past), one perfect, differ in meaning:
I lost my keys.
I have lost my keys.
?
When I put this question to students (young and old) in my NT Greek class, no one can answer it to his satisfaction. But the fault isn’t theirs. It is, in fact, very difficult to detect any differences when comparing such sentences in isolation, that is, detached from a real-world situation. I mean that in the mundane course of things sentences are accompanied by other sentences, knowledge of the world, the present situation (including the act of uttering the sentence), background assumptions, and other interpretive constraints. All these data provide context by which we interpret the meaning of a sentence.
I would answer my question as follows: the aorist “I lost my keys.” implies what may well be a temporary condition. In fact, at the time of utterance, the keys may no longer be lost. This cannot be said for the perfect “I have lost my keys.” Its use implies a persistent, if not permanent, state. More subtly, proper interpretation of the aorist seems to require context, whereas the perfect, giving only stative information, does not.
But this claim is better illustrated by a more realistic example:
Socrates felt cold. He lay down, gestured weakly to his friends, and closed his eyes. He moaned. It would soon be dawn.
This utterance is readily interpreted as follows: before dawn and all the while feeling cold, Socrates first lay down, then gestured, then closed his eyes; finally, he moaned. The context tells us that the last thing he did, still before dawn, was to moan. We don’t know exactly when he moaned or how many times. But we do know that he moaned after lying down, gesturing, and closing his eyes.
If we now replace the aorist “moaned” with a perfect construction, e.g.,
Socrates felt cold. He lay down, gestured weakly to his friends, and closed his eyes. He had moaned. It would soon be dawn.
we could infer that Socrates’ moaning occurred before, during, or after his lying down.
Thus the perfect permits inferences that do not, unlike the aorist, depend on the context.
Cordially,
