Sophia, yesterday we found five jobs for “to be”, and the voice at the bush used only one of them: existence. But I still don’t understand that one. When God said “I am”, what kind of “is” was it?

Philo and Sophia · Prequel · The verb to be
Am, is, are, was, were, be, being and been: the most irregular verb in the language, taken apart at the foot of a burning bush, and then put under the ten lenses of Aristotle’s Categories, by Sophia, with Philo defending the one answer that fits none of them.

Sophia, yesterday we found five jobs for “to be”, and the voice at the bush used only one of them: existence. But I still don’t understand that one. When God said “I am”, what kind of “is” was it?

Then let us read the passage again, slowly, as a text to take apart. First the forms of the verb itself, then the philosophy. I have brought a friend for the second part. His name is Aristotle.
After Exodus 3, in the Greek of the Septuagint
Moses was looking after the sheep of his father-in-law Jethro, and he led them to the far side of the desert, to Horeb, the mountain of God. And the angel of the Lord appeared to him in a flame of fire out of the middle of a bush. He looked, and saw that the bush was burning with fire, and yet the bush was not burned up.
Moses said, “I will turn aside and see this great sight: why the bush is not burned up.” And God called to him out of the bush: “Moses, Moses.” And he said, “Here I am.” “Do not come near. Take off your sandals from your feet, for the place where you are standing is holy ground.”
Moses asked, “If the children of Israel say to me, ‘What is his name?’, what shall I tell them?” And God said to Moses: “I am the One who is.” And he said: “Thus you shall say to the children of Israel: The One who is has sent me to you.”
Exodus 3, from the Greek of the Septuagint, where God’s answer is “Egō eimi ho ōn”. In the Hebrew, it is “ehyeh asher ehyeh”, often translated “I am who I am”.
Aristotle (384–322 BCE) was the teacher of Alexander the Great, who founded our city. His short book the Categories sorts everything that can be said about a thing into ten kinds. In his Metaphysics he wrote the famous sentence: “Being is said in many ways.” His works were being carefully edited in the generation before our gang, and scholars in Alexandria studied them closely.
A Jewish scholar of Alexandria called Philo, who lived at exactly this time, wrote that God’s answer at the bush means that God is Being itself. Readers may wonder whether our Philo is the same young man.
The forms: eight words for one verb

I counted. be, am, is, are, was, were, being, been. Eight different words. Every other verb has four or five.

It is the most irregular verb in English, and in Greek too: eimi, esti, ēn, esomai. English built it from three different old verbs, like a house made from three ruins: is, was and be.

Present: I am, you are, he / she / it is, we / they are. Past: I / he / she / it was, you / we / they were. And been for the perfect: I have been. being for the continuous and after prepositions: without being seen.
No need for do

So I ask “Does the bush be burning?”

Never. be makes its own questions and negatives, with no do: Is it burning? It isn’t burning. Were you there? I wasn’t. The only exception is the imperative: Don’t be afraid. Do be careful.

And the short forms: I’m, you’re, he’s, it’s, we’re, they’re; isn’t, aren’t, wasn’t, weren’t. And, strangely, aren’t I? in a question, because English has no good short form of “am not”.
There is, there are: pure existence

“There is a bush on the mountain.” The bush doesn’t do anything. It is just there.

Exactly: there is / there are announce that something exists, in the singular or the plural, before we say anything else about it: There was a flame. There were sheep.
Aristotle: ten ways of saying “is”

Now, Aristotle. He noticed that when we say that something is, we can mean ten different kinds of thing. He called them categories, and each answers a different question. Let us test them on the burning bush.

Ten? I thought we had five uses already.

The five uses are grammar: what the verb does in the sentence. The ten categories are philosophy: what kind of thing we are saying about the world. The grammar and the philosophy fit together surprisingly well. Watch.
Substance, quantity, quality, relation

Substance, the answer to “what is it?”: Moses is a man. It is a bush. A noun after is.

Quantity, “how much, how big?”: The bush is three cubits tall. Quality, “what kind?”: The flame is bright. An adjective.

Relation: Aaron is Moses’s brother. The mountain is higher than the hill. So that’s where comparatives live.

Very good, Marcos. Relation is every “than”, every “brother of”, every “double”.
Place, time, position, having

Place, “where?”: Moses is on the mountain. Time, “when?”: The vision was at midday. Prepositional phrases.

Position, how a thing is placed: Moses is kneeling. The sheep are lying down. And having, or state: Moses is barefoot, because God told him to take off his sandals.
Action and affection: the bush itself

And the last two are the most beautiful, because the bush is made of them. Action, “what is it doing?”: The bush is burning. That is be + -ing, the continuous. Affection, “what is being done to it?”: The bush is not consumed. That is be + past participle, the passive.

Burning, but not burned up. It’s doing the action, but not suffering it. That’s the whole miracle, in two categories.
The answer that fits no category

And now try God’s answer. “I am the One who is.” What category? Not substance, a kind of thing. Not quality, not quantity, not place, not time. He doesn’t say what he is like, or where, or what he is doing. He just is.

Aristotle would agree that there is a puzzle here. He said that being itself is not a category, because it runs through all of them. Philo, you are saying that your scriptures put God there: not inside any category, but above them all.

Yes.

Then you’ve understood the verb better than most philosophers. Next, we meet some other verbs that behave just like “be”: they don’t do anything at all, they only link a subject to what we say about it.
